* soft-fp: Refactor exception handling for comparisons.Joseph Myers2014-10-0917-55/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.

* soft-fp: Remove FP_CLEAR_EXCEPTIONS.Joseph Myers2014-10-094-12/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in <https://sourceware.org/ml/libc-alpha/2013-10/msg00516.html>, the soft-fp macro FP_CLEAR_EXCEPTIONS should not be necessary, as soft-fp code should never set an exception and later clear it. In fact, all four uses in glibc (for SPARC) are indeed unnecessary: they appear in files that convert 32-bit or 64-bit integers to IEEE binary128, an operation that can never raise any exceptions. If this was intended to enable the compiler to optimize away any FP_FROM_INT code testing for exceptional cases, we now have a better way of doing this: defining FP_NO_EXCEPTIONS before including soft-fp.h causes all code handling exceptions to be stubbed out, and the rounding mode to be hardwired for round-to-zero, to allow such optimizations for source files where (a) the operation in question, for the particular types in question, can never raise exceptions, but (b) some instances of the operation for other types can, so the macros used in the file do contain references to rounding or exceptions, albeit dead in that particular file. The uses in the Linux kernel are also unnecessary (clearing exceptions at a point where they are already cleared). This patch duly removes FP_CLEAR_EXCEPTIONS, making the SPARC code in question use FP_NO_EXCEPTIONS and stop using exception-related macros. * soft-fp/soft-fp.h (FP_CLEAR_EXCEPTIONS): Remove macro. * sysdeps/sparc/sparc32/soft-fp/q_itoq.c: Define FP_NO_EXCEPTIONS.

* Don't use INTUSE with __adjtimex (bug 14132).Joseph Myers2014-10-086-12/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 14132 is removal of the old INTDEF/INTUSE system of *_internal aliases as obsoleted by the hidden_proto / hidden_def system. Various cases were cleaned up in 2012, but some remain. This patch removes the use of this mechanism for __adjtimex. Tested for x86_64 that stripped installed shared libraries are unchanged by the patch.

* Support and use mixed compat/non-compat aliases in syscalls.list.Joseph Myers2014-10-066-47/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables syscalls.list entries to specify both compat and non-compat symbol versions for the same syscall definition, making use of this for setrlimit / chown / lchown where the inability to specify such aliases showed up in the course of work on bug 14138. The change to make-syscalls.sh is minimal: adding a SHARED conditional on the compat_symbol calls. It remains the case that if a compat symbol version is specified, the syscall is only built for the shared library at all if an explicit symbol version is given for a non-compat symbol (so it's necessary to specify "lchown@@GLIBC_2.0 chown@GLIBC_2.0" rather than just "lchown chown@GLIBC_2.0"). It also remains the case, as already commented in make-syscalls.sh, that no SHLIB_COMPAT conditionals are generated, so there would be problems if the same syscalls.list file, with compat symbols, were used for both configurations that should have those symbols and configurations for which they should be conditioned out with SHLIB_COMPAT. Tested for x86. * sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Condition compat_symbol calls on [SHARED]. * sysdeps/unix/sysv/linux/powerpc/lchown.S: Remove file. * sysdeps/unix/sysv/linux/i386/syscalls.list (oldsetrlimit): Remove.

* Move some chown / lchown / fchown definitions to syscalls.list (bug 14138).Joseph Myers2014-10-068-47/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves various definitions of chown, lchown and fchown. In most cases the need for special syscalls.list entries (rather than existing generic ones) is because these architectures use chown32, lchown32 and fchown32 as syscall names. Some architectures also have symbol versioning compatibility for older versions of chown having been equivalent to lchown. In the case of powerpc, chown.c (providing the chown@@GLIBC_2.1 default version) is replaced by a syscalls.list entry (for powerpc32; powerpc64 has no need for this because of its more recent minimum symbol version, so can just use the entry in sysdeps/unix/syscalls.list), but lchown.S is left as-is because it provides the compat version of chown as an actual alias for __lchown, which is not yet supported by syscalls.list. This file can be removed once such aliases are supported in syscalls.list. [BZ #14138] * sysdeps/unix/sysv/linux/arm/fchown.c: Remove file. * sysdeps/unix/sysv/linux/arm/lchown.c: Likewise. * sysdeps/unix/sysv/linux/m68k/fchown.c: Likewise. * sysdeps/unix/sysv/linux/m68k/lchown.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/chown.c: Likewise. * sysdeps/unix/sysv/linux/arm/syscalls.list (lchown): Add syscall.

* tile: optimize memcmpChris Metcalf2014-10-061-0/+367
| | | | | | | | | | | | | | Customize memcmp.c for tile, using similar tricks from memcpy: - replace MERGE macro with dblalign. - replace memcmp_bytes function with revbytes. - use __glibc_likely. - use post-increment addressing. The schedule is still not perfect: the compiler is not hoisting code above the comparison branch, which could save a bundle or two. memcmp speeds up by 30-40% on shorter aligned tests in benchtest, with some tests with unaligned lengths taking a small performance hit.

* tilegx: provide optimized strnlen, strstr, and strcasestrChris Metcalf2014-10-064-5/+401
| | | | | | | | | | | | | | | | | | | | | | strnlen() is based on the existing tile strlen() with length checking added. It speeds up by up to 5x, but on average across the benchtest corpus by around 35%. No regressions are seen. strstr() does 8-byte aligned loads and compares using a 2-byte filter on the first two bytes of the needle and then testing the remaining bytes in needle using memcmp(). It speeds up about 5x in the best case (for "found" needles), about 2x looking at benchtest as a whole, with some slowdowns as much as 45%. on a few cases (including the "fail" case for 128KB search). strcasestr() is based on strstr() but uses a SIMD tolower routine to convert 8-bytes to lower case in 5 instructions. It also uses a 2-byte filter and then strncasecmp() for the remaining bytes. strncasecmp() is not optimized for SIMD, so there is futher room for improvement. However, it is still up to 16x faster for "found" needles, averaging 2x faster on the whole corpus of benchtests. It does slow down by up to 35% on a few cases, similarly to strstr().

* Move execve to syscalls.list (bug 14138).Joseph Myers2014-10-012-35/+1
| | | | | | | | | | | | | | Continuing the move of syscall definitions to syscalls.list, where previous cleanups have made this possible, this patch moves the definition of execve. (In this case, it was the removal of bounded pointers support, rather than old kernel support, which made the move possible.) Tested for x86_64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves definitions of various *at functions in sysdeps/unix/sysv/linux/. These particular moves are straightforward: there are no #includes of these source files, no special architecture-specific versions, no special symbol version handling and no aliases. Each source file can be replaced by a single line in sysdeps/unix/sysv/linux/syscalls.list. Tested for x86_64. [BZ #14138] * sysdeps/unix/sysv/linux/syscalls.list (fchownat): New syscall.

* Remove shlib-versions entries redundant with DEFAULT entries.Joseph Myers2014-09-264-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a shlib-versions file has a DEFAULT line, it's not necessary to specify the same default minimum symbol version on the lines for individual libraries. If those lines otherwise duplicate the default SONAME for the library in question, they can be removed completely. This patch makes such cleanups: version entries for ld.so are removed (leaving just the definition of the architecture-specific dynamic linker name) and entries for libpthread are removed completely (since the default is libpthread.so.0). Tested for x86_64 that the installed shared libraries are unchanged by this patch. There are various architectures (hppa, ia64, mips, sh, sparc64) that define minimum symbol versions (or in the case of mips, omission of symbol versions) only for particular libraries without a DEFAULT line. None of these are equivalent to something simpler with a DEFAULT line because all have some other libraries, not explicitly mentioned, with symbol versions that would be omitted were such a line used. In the mips case I'm pretty sure it was a mistake not to omit the 2.1 symbols for libthread_db; for the others I don't know if it was a mistake or deliberate that some symbols in various libraries have 2.0 or 2.1 versions despite other libraries having a 2.2 minimum. This concludes the shlib-versions cleanups I'm aware of. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Do not specify symbol version for ld.so.

* Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers2014-09-2611-22/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64.

* Move some setrlimit definitions to syscalls.list (bug 14138).Joseph Myers2014-09-2310-43/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 14138 is followup cleanup after removal of support for old Linux kernel versions: moving syscalls to syscalls.list where the only reason for using C definitions was kernel version conditionals that are no longer present. This patch deals with the case of setrlimit (sysdeps/unix/sysv/linux/i386/setrlimit.c, included by various other architectures). Where needed (where there is also a compat symbol for setrlimit@GLIBC_2.0), new syscalls.list entries are added. Where not needed (where there is no such compat symbol and the minimum symbol version for libc is 2.2 or later), no such entries are added as that in sysdeps/unix/syscalls.list will suffice. Thus arm and sh need no such entries, while m68k and powerpc need entries only in a subdirectory syscalls.list file rather than for all configurations that previously used setrlimit.c. (setrlimit@@GLIBC_2.2 and setrlimit@GLIBC_2.0 are now semantically identical - the new symbol version was about a change of types from signed to unsigned and the former compatibility code for dealing with large unsigned arguments on old kernels is no longer needed or present, having been removed with support for pre-2.4 kernels. However, making the two versions into aliases doesn't work at present: the case of having both default and non-default symbol versions on the same syscalls.list line results in a compat_symbol call in code built for static libc, which doesn't compile. I don't suppose it would be hard to generate SHARED conditionals from make-syscalls.sh to fix this, but in any case this patch doesn't make things any worse, as the functions weren't aliases before the patch either.) Tested for x86, and ran ABI tests for ARM as an example of an architecture where the setrlimit.c file was just removed without adding syscalls.list entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the first column (patterns matching configuration names) from shlib-versions, leaving shlib-versions entry selection based purely on sysdeps directories. An implication of this removal is that the default for any non-Linux ports using NPTL will be the same SONAMEs for NPTL libraries as for Linux (as those defaults, previously limited to .*-.*-linux.*, are left in nptl/shlib-versions and nptl_db/shlib-versions). Special host_os handling in configure.ac that was purely for shlib-versions is removed. (The host_os setting is still used for libc-abis - see <https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding that - but no entries there are affected by this change.)

* Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.Joseph Myers2014-09-123-2/+10
| | | | | | | | | | | | | | | | | | | | | | | This patch makes sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions use %ifdef conditionals around the different symbol version definitions for big and little endian. (It doesn't actually change the host patterns used for those definitions; the point is to make it possible to remove the first column from shlib-versions by eliminating the last case where it would be harmful for it to be treated as .*-.*-.*.) The conditional is based on the ELFv1/ELFv2 distinction rather than BE/LE, since that's what's already tested in configure and used for the ld.so soname in the Makefiles. (Of course if BE ELFv2 were supported in future, it would get new symbol versions and so need new conditionals.) * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac (HAVE_ELFV2_ABI): AC_DEFINE in ELFv2 case. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * config.h.in (HAVE_ELFV2_ABI): New macro undefine. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Condition symbol version definitions on [HAVE_ELFV2_ABI].
* Move OS-specific shlib-versions entries to sysdeps files.Joseph Myers2014-09-122-0/+14
| | | | | | | | | | | | | | | | | | | | | | | This patch moves OS-specific entries in the top-level shlib-versions file to appropriate sysdeps directories. I left the entries in nptl/shlib-versions and nptl_db/shlib-versions unchanged; I think it can be for those doing non-Linux NPTL-using ports to figure out whether those entries should actually be OS-independent or should move to sysdeps. Given these two patches, I think the only further change needed before the first column of shlib-versions can be eliminated will be changing sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions to use %ifdef to distinguish BE and LE configurations, instead of relying on the powerpc64-.*-linux.* and powerpc.*le-.*-linux.* patterns. Tested on x86_64 that the installed shared libraries are unchanged by this patch. * shlib-versions: Remove OS-specific entries.

* Move architecture-specific shlib-versions entries to sysdeps files.Joseph Myers2014-09-125-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch eliminates another way in which ex-ports and non-ex-ports architectures differ, by moving architecture-specific entries from the top-level shlib-versions file and that in nptl/ to appropriate sysdeps directories. As with my previous patch <https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>, I do not change the regular expressions used; even where the present expressions seem more general, I believe they are in fact specific to the chosen sysdeps directory, because any port that matches the expression but not the sysdeps directory does not currently exist, and so would use different symbol versions if added in future (and an intended goal of these changes is to eliminate the first column in shlib-versions completely rather than having two different mechanisms in use for system-specific configuration). Tested on x86_64 that this does not change the installed shared libraries. (x86_64 of course does not provide much test coverage for this patch - what should be architecture-specific contents in shlib-versions for x86_64 is currently abi-*-ld-soname Makefile settings, until gnu/lib-names.h is generated more like gnu/stubs.h so those can move back to shlib-versions.) * nptl/shlib-versions: Remove architecture-specific entries.

* PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella2014-09-106-9/+513
| | | | | | | | | | | | | | | | | | | This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes.

* [BZ #17354] tile: Fix up corner cases with signed relocationsChris Metcalf2014-09-061-18/+23
| | | | | | | | | | | | | | | | | | Some types of relocations technically need to be signed rather than unsigned: in particular ones that are used with moveli or movei, or for jump and branch. This is almost never a problem. Jump and branch opcodes are pretty much uniformly resolved by the static linker (unless you omit -fpic for a shared library, which is not recommended). The moveli and movei opcodes that need to be sign-extended generally are for positive displacements, like the construction of the address of main() from _start(). However, tst-pie1 ends up with main below _start (in a different module) and the test failed due to signedness issues in relocation handling. This commit treats the value as signed when shifting (to preserve the high bit) and also sign-extends the value generated from the updated bundle when comparing with the desired bundle, which we do to make sure no overflow occurred. As a result, the tst-pie1 test now passes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLS_INIT_TP in sysdeps/i386/nptl/tls.h uses some hand written asm to generate a set_thread_area that might result in exchanging ebx and esp around the syscall causing introspection tools like valgrind to loose track of the user stack. Just use INTERNAL_SYSCALL which makes sure esp isn't changed arbitrarily. Before the patch the code would generate: mov $0xf3,%eax movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %esp,%ebx int $0x80 xchg %esp,%ebx Using INTERNAL_SYSCALL instead will generate: movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %ecx,%ebx mov $0xf3,%eax int $0x80 xchg %ecx,%ebx Thanks to Florian Weimer for analysing why the original code generated the bogus esp usage: _segdescr.desc happens to be at the top of the stack, so its address is in %esp. The asm statement says that %3 is an input, so its value will not change, and GCC can use %esp as the input register for the expression &_segdescr.desc. But the constraints do not fully describe the asm statement because the %3 register is actually modified, albeit only temporarily.

* Fix powerpc32 __get_clockfreq for non-power4 (bug 17263).Joseph Myers2014-08-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In my powerpc32 testing I've observed misc/test-gettimebasefreq failing. This is a glibc build (soft-float, though that's not relevant here) without any --with-cpu and without any special configuration of the default CPU for GCC either. In particular, it's one not using sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the processor I'm using for testing is POWER4-based), so hp_timing_t is 32-bit not 64-bit. But the VDSO call being used by INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result (high part in r3, low part in r4). The code extracting that result, however, expects a result of the type hp_timing_t as passed to INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is used and the value in r4 is ignored. This patch fixes this by always using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK - reflecting the actual ABI (unconditional in the kernel) of that VDSO call. This is the minimal change for this issue - no check for overflow, no change of the type of the timebase_freq variable or the return type of __get_clockfreq to something other than hp_timing_t (such a change would simply move the implicit conversions to the over callers of that function), no change to hp_timing_t itself. Tested for powerpc32 soft float. [BZ #17263] * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Include <stdint.h>. (__get_clockfreq): Use uint64_t instead of hp_timing_t in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK call.
