* Installed header hygiene (BZ#20366): Test of installed headers.Zack Weinberg2016-09-231-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a test to ensure that the problems fixed in the last several patches do not recur. Each directory checks the headers that it installs for two properties: first, each header must be compilable in isolation, as both C and C++, under a representative combination of language and library conformance levels; second, there is a blacklist of identifiers that may not appear in any installed header, currently consisting of the legacy BSD typedefs. (There is an exemption for the headers that define those typedefs, and for the RPC headers. It may be necessary to make this more sophisticated if we add more stuff to the blacklist in the future.) In order for this test to work correctly, every wrapper header that actually defines something must guard those definitions with #ifndef _ISOMAC. This is the existing mechanism used by the conform/ tests to tell wrapper headers not to define anything that the public header wouldn't, and not to use anything from libc-symbols.h. conform/ only cares for headers that we need to check for standards conformance, whereas this test applies to *every* header. (Headers in include/ that are either installed directly, or are internal-use-only and do *not* correspond to any installed header, are not affected.) * scripts/check-installed-headers.sh: New script. * Rules: In each directory that defines header files to be installed, run check-installed-headers.sh on them as a special test. * Makefile: Likewise for the headers installed at top level. * include/aliases.h, include/alloca.h, include/argz.h * include/arpa/nameser.h, include/arpa/nameser_compat.h * include/elf.h, include/envz.h, include/err.h * include/execinfo.h, include/fpu_control.h, include/getopt.h * include/gshadow.h, include/ifaddrs.h, include/libintl.h * include/link.h, include/malloc.h, include/mcheck.h * include/mntent.h, include/netinet/ether.h * include/nss.h, include/obstack.h, include/printf.h * include/pty.h, include/resolv.h, include/rpc/auth.h * include/rpc/auth_des.h, include/rpc/auth_unix.h * include/rpc/clnt.h, include/rpc/des_crypt.h * include/rpc/key_prot.h, include/rpc/netdb.h * include/rpc/pmap_clnt.h, include/rpc/pmap_prot.h * include/rpc/pmap_rmt.h, include/rpc/rpc.h * include/rpc/rpc_msg.h, include/rpc/svc.h * include/rpc/svc_auth.h, include/rpc/xdr.h * include/rpcsvc/nis_callback.h, include/rpcsvc/nislib.h * include/rpcsvc/yp.h, include/rpcsvc/ypclnt.h * include/rpcsvc/ypupd.h, include/shadow.h * include/stdio_ext.h, include/sys/epoll.h * include/sys/file.h, include/sys/gmon.h, include/sys/ioctl.h * include/sys/prctl.h, include/sys/profil.h * include/sys/statfs.h, include/sys/sysctl.h * include/sys/sysinfo.h, include/ttyent.h, include/utmp.h * sysdeps/arm/nacl/include/bits/setjmp.h * sysdeps/mips/include/sys/asm.h * sysdeps/unix/sysv/linux/include/sys/sysinfo.h * sysdeps/unix/sysv/linux/include/sys/timex.h * sysdeps/x86/fpu/include/bits/fenv.h: Add #ifndef _ISOMAC guard around internal declarations.

* Installed-header hygiene (BZ#20366): stack_t.Zack Weinberg2016-09-231-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.

* Add femode_t functions.Joseph Myers2016-09-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TS 18661-1 defines a type femode_t to represent the set of dynamic floating-point control modes (such as the rounding mode and trap enablement modes), and functions fegetmode and fesetmode to manipulate those modes (without affecting other state such as the raised exception flags) and a corresponding macro FE_DFL_MODE. This patch series implements those interfaces for glibc. This first patch adds the architecture-independent pieces, the x86 and x86_64 implementations, and the <bits/fenv.h> and ABI baseline updates for all architectures so glibc keeps building and passing the ABI tests on all architectures. Subsequent patches add the fegetmode and fesetmode implementations for other architectures. femode_t is generally an integer type - the same type as fenv_t, or as the single element of fenv_t where fenv_t is a structure containing a single integer (or the single relevant element, where it has elements for both status and control registers) - except where architecture properties or consistency with the fenv_t implementation indicate otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic pointer value (-1 cast to const femode_t *), a value that can be distinguished from valid pointers by its high bits but otherwise contains a representation of the desired register contents, or a pointer to a constant variable (the powerpc case; __fe_dfl_mode is added as an exported constant object, an alias to __fe_dfl_env). Note that where architectures (that share a register between control and status bits) gain definitions of new floating-point control or status bits in future, the implementations of fesetmode for those architectures may need updating (depending on whether the new bits are control or status bits and what the implementation does with previously unknown bits), just like existing implementations of <fenv.h> functions that take care not to touch reserved bits may need updating when the set of reserved bits changes. (As any new bits are outside the scope of ISO C, that's just a quality-of-implementation issue for supporting them, not a conformance issue.) As with fenv_t, femode_t should properly include any software DFP rounding mode (and for both fenv_t and femode_t I'd consider that fragment of DFP support appropriate for inclusion in glibc even in the absence of the rest of libdfp; hardware DFP rounding modes should already be included if the definitions of which bits are status / control bits are correct). Tested for x86_64, x86, mips64 (hard float, and soft float to test the fallback version), arm (hard float) and powerpc (hard float, soft float and e500).

* Fix MIPS64 memcpy regression.Steve Ellcey2016-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS memcpy optimizations at <https://sourceware.org/ml/libc-alpha/2015-10/msg00597.html> introduced a bug causing many string function tests to fail with segfaults for n32 and n64: FAIL: string/stratcliff FAIL: string/test-bcopy FAIL: string/test-memccpy FAIL: string/test-memcmp FAIL: string/test-memcpy FAIL: string/test-memmove FAIL: string/test-mempcpy FAIL: string/test-stpncpy FAIL: string/test-strncmp FAIL: string/test-strncpy (Some failures in other directories could also be caused by this bug.) The problem is that after the check for whether a word of input is left that can be copied as a word before moving to byte copies, a load can occur in the branch delay slot, resulting in a segfault if we are at the end of a page and the following page is unmapped. I don't see how this would have passed the tests as reported in the original patch posting (different kernel configurations affecting the code setting up unmapped pages, maybe?), since the tests in question don't appear to have changed recently. This patch moves a later instruction into the delay slot, as suggested at <https://sourceware.org/ml/libc-alpha/2016-01/msg00584.html>.

* Fix ulps regeneration for *-finite tests.Joseph Myers2016-01-192-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On running tests after from-scratch ulps regeneration, I found that some libm tests failed with ulps in excess of those recorded in the from-scratch regeneration, which should never happen unless those ulps exceed the limit on ulps that can go in libm-test-ulps files.

Those tests share ulps with the default function variants. make regen-ulps runs the default tests before the finite-math-only tests, concatenating the resulting ulps before feeding them to gen-libm-test.pl to generate a new libm-test-ulps file. But gen-libm-test.pl always takes the last ulps value given for any (function, type) pair. So, if the largest ulps for a function come from non-finite inputs, a from-scratch regeneration loses those ulps. This patch fixes gen-libm-test.pl, in the case where there are multiple ulps values for a (function, type) pair - which can only happen as part of a regeneration - to take the largest ulps value rather than the last one.

* S/390: Do not raise inexact exception in lrint/lround. [BZ #19486]Stefan Liebler2016-01-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I get some math test-failures on s390 for float/double/ldouble for various lrint/lround functions like: lrint (0x1p64): Exception "Inexact" set lrint (-0x1p64): Exception "Inexact" set lround (0x1p64): Exception "Inexact" set lround (-0x1p64): Exception "Inexact" set ... GCC emits "convert to fixed" instructions for casting floating point values to integer values. These instructions raise invalid and inexact exceptions if the floating point value exceeds the integer type ranges. This patch enables the various FIX_DBL_LONG_CONVERT_OVERFLOW macros in order to avoid a cast from floating point to integer type and raise the invalid exception with feraiseexcept.

It assumes that it is possible to use the -mfp64 option to build tst-abi-fp64amod and tst-abi-fp64mod, while this requires a CPU which supports the mfhc1 and mthc1 instructions, ie at least a R2 CPU: error: '-mgp32' and '-mfp64' can only be combined if the target supports the mfhc1 and mthc1 instructions The same way it assumes that it is possible to use the -modd-spreg option to build tst-abi-fpxxomod and tst-abi-fp64mod, while this requires at least a R1 CPU: warning: the 'mips2' architecture does not support odd single-precision registers This patches changes that by checking the usability of -mfp64 and -modd-spreg options in configure, and disable those tests when they can not be used.
* math: add LDBL_CLASSIFY_COMPAT supportChris Metcalf2015-12-031-0/+4
| | | | | | | | | | | | | | | | | If a platform does not define "long-double-fcts = yes" in its Makefiles and it does define __NO_LONG_DOUBLE_MATH in its installed headers, it will currently create exported symbols for __finitel, __isinfl, and __isnanl that can't be reached from userspace by correct use of the finite(), isinf(), or isnan() macros in <math.h>. To avoid this situation, by default for such platforms we now no longer export these symbols, thus causing appropriate link-time errors. However, for platforms that previously exported these symbols, we continue to do so as compat symbols; this is enabled by adding LDBL_CLASSIFY_COMPAT to math_private.h for the platform. For tile, remove the now-unnecessary exports of those functions from libc and libm.
* MIPS: Wire FCSR.ABS2008 to FCSR.NAN2008Maciej W. Rozycki2015-11-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revision 3.50 of the MIPS architecture defined FCSR ABS2008 and NAN2008 bits as optionally read/write [1][2]. No hardware implementation has ever made use of this feature though. For example the first processor to implement these bits, the MIPS32r3 proAptiv core, has both bits read-only, hardwired to 1 [3]. And as from revision 5.03 of the MIPS architecture the bits are required to be read-only, preset by hardware [4][5]. Additionally all hardware implementations in existence have the bits hardwired both to the same value, either of `0' and `1'. These bits may still be read/write or hardwired to opposite values in simulated hardware implementations such as QEMU or the FPU emulator included with the Linux kernel. However to match real hardware implementations the Linux kernel will set FCSR ABS2008 and NAN2008 bits both to the same value where possible, reflecting the setting of the EF_MIPS_NAN2008 ELF file header bit. Therefore update the bit patterns in macro definitions we use for the control word, in the 2008-NaN encoding mode, so that both bits have the same value in a given bit pattern. Additionally mark the FCSR ABS2008 bit as reserved, so that high-level calls to change the control word do not affect the bit. This covers the regular FPU configurations, only leaving exotic corner cases with the value of FCSR control word initially set by the kernel different to what our code thinks it is. To address the remaining cases the AT_FPUCW auxiliary vector entry would have to be implemented in the Linux kernel, which currently is not.

* Fix math_private.h multiple include guards.Joseph Myers2015-11-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various math_private.h headers are guarded by "#ifndef _MATH_PRIVATE_H", but never define the macro. Nothing else defines the macro either (the generic math_private.h that they include defines a different macro, _MATH_PRIVATE_H_), so those guards are ineffective. With the recent inclusion of s_sin.c in s_sincos.c, this breaks the build for MIPS, since the build of s_sincos.c ends up including <math_private.h> twice and the MIPS version defines inline functions such as libc_feholdexcept_mips, without a separate fenv_private.h header with its own guards such as some architectures have. This patch fixes all the problem headers to use architecture-specific guard macro names, and to define those macros in the headers they guard, just as some architectures already do. Tested for x86 (testsuite, and that installed shared libraries are unchanged by the patch), and for mips64 (that it fixes the build). * sysdeps/arm/math_private.h [!_MATH_PRIVATE_H]: Change guard to [!ARM_MATH_PRIVATE_H].

* Fix lrint, llrint, lround, llround missing exceptions for MIPS (bug 16399).Joseph Myers2015-10-091-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 32-bit MIPS and some other systems, various of the lrint, llrint, lround, llround functions can be missing exceptions on overflow because casts do not (in current GCC) result in the proper exceptions. In the MIPS case there are two problems here: MIPS I code generation uses an assembler macro that doesn't raise exceptions, while the libgcc conversions of floating-point values to long long also do not raise "invalid" on all overflow cases (and can raise spurious "inexact"). This patch adds support in the generic code (only the functions for which this problem has actually been seen) for forcing the "invalid" exception in the problem cases, and enables that support for the affected MIPS cases. Tested for MIPS; also tested for x86_64 and x86 that installed stripped shared libraries are unchanged by this patch.

| | | | | | | | | | | | | | | | | | | | | This patch adds more libm test inputs found through random test generation to increase previously known ulps.

* MIPS: Only use .set mips* assembler directives when necessaryAndrew Bennett2015-09-084-19/+36
| | | | | | | | | | | | | | | | | | | | | | There are a few .set mips* assembler directives used in the MIPS specific sysdep code that force an instruction to be assembled for a specific ISA. The reason for these is to allow an instruction to be encoded when it might not be supported in the current ISA (when the code is run the Linux kernel will trap and emulate any unsupported instructions). Unfortunately forcing a specific ISA means that when assembling for a newer ISA, where the instruction has a different encoding, the wrong encoding will be used. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIO32] (MIPS_PUSH_MIPS2): Only use .set mips2 if the current ISA is below mips2. * sysdeps/mips/sys/tas.h [_MIPS_SIM == _ABIO32] (_test_and_set): Likewise. * sysdeps/mips/nptl/tls.h (READ_THREAD_POINTER): Only use .set mips32r2 if the current ISA is below mips32r2. * sysdeps/mips/tls-macros.h (TLS_RDHWR): New define.

* Fix mips16 __fpu_control static linking (bug 18397).Joseph Myers2015-05-112-1/+4
| | | | | | | | | | | | | | | | | | | | | Programs are supposed to be able to define the __fpu_control variable, overriding the library's version to cause the floating-point control word to be set to the chosen value at startup. This is broken for mips16 for static linking because the library's __fpu_control variable is in the same object file as the helper functions used by fpu_control.h for mips16, so test-fpucw-ieee-static fails to link with multiple definitions of __fpu_control. This patch fixes this by putting the helpers in a separate file rather than overriding fpu_control.c. Tested for mips16 that this fixes the link failure and the ABI tests still pass. [BZ #18397] * sysdeps/mips/mips32/fpu/fpu_control.c: Move to .... * sysdeps/mips/mips32/fpu/fpucw-helpers.c: ... here.

| | | | | | | | | | | | | | | | | | This patch disables use of 64-bit atomics for MIPS n32 to fix the problems with unaligned semaphores. Before 64-bit atomics are used for anything for which such alignment issues do not arise, and before the addition of any new ILP32 ports with 64-bit semaphores for which the ABI can be set to have the greater alignment (AARCH64?), a better approach will need to be established that allows architectures to declare their 64-bit atomics availability accurately, without doing so causing inappropriate use of such atomics on unaligned semaphores.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of fesetenv by making it a weak alias of __fesetenv and making the affected code (including various copies of feupdateenv which also gets called from C90 functions) call __fesetenv. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that fesetenv failures disappear from the linknamespace test results (fsetround and feupdateenv remain to be addressed to complete fixing bug 17748).
