* Fix sNaN handling in nearbyint on 32-bit sparc.David S. Miller2016-08-025-10/+20
| | | | | | | | | | | | * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Don't check for sNaN before float register is loaded with the incoming argument. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_nearbyint.S (__nearbyint): Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_nearbyintf.S (__nearbyintf): Likewise.

* powerpc: fix ifunc-sel.h fix asm constraints and clobber listAurelien Jarno2016-08-032-2/+8
| | | | | | | | | | | | | | | As pointer out on the mailing list, the inline assembly code in sysdeps/powerpc/ifunc-sel.h doesn't have a list of clobbered registers and used wrong constraints. This patch fixes that. I verified it doesn't introduce any change in the generated code. Changelog: * sysdeps/powerpc/ifunc-sel.h (ifunc_sel): Add "11", "12", "cr0" to the clobber list. Use "i" constraint instead of "X". (ifunc_one): Add "12" to the clobber list. Use "i" constraint instead of "X".
* powerpc: fix ifunc-sel.h with GCC 6Aurelien Jarno2016-08-032-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit PowerPC GCC 6 always saves the PIC register on the stack in the prologue and adjust the stack in the epilogue. It is therefore not possible anymore to just exit the function in the inline asm code, otherwise it corrupts the stack pointer. This causes the following tests to fail when using GCC 6: FAIL: elf/ifuncmain1 FAIL: elf/ifuncmain1pic FAIL: elf/ifuncmain1picstatic FAIL: elf/ifuncmain1pie FAIL: elf/ifuncmain1staticpic FAIL: elf/ifuncmain1staticpie FAIL: elf/ifuncmain1vis FAIL: elf/ifuncmain1vispic FAIL: elf/ifuncmain1vispie FAIL: elf/ifuncmain2pic FAIL: elf/ifuncmain2picstatic FAIL: elf/ifuncmain3 FAIL: elf/ifuncmain4picstatic FAIL: elf/ifuncmain5 FAIL: elf/ifuncmain5picstatic FAIL: elf/ifuncmain5staticpic The solution is to replace the beqlr instructions by a beq to the end of the inline asm code. This fixes all the above failures. ChangeLog: * sysdeps/powerpc/ifunc-sel.h (ifunc_sel): Replace beqlr instructions by beq instructions jumping to the end of the function.
* Support __STDC_WANT_LIB_EXT2__ feature test macro.Joseph Myers2016-08-029-11/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements support for the __STDC_WANT_LIB_EXT2__ feature test macro from ISO/IEC TR 24731-2:2010, thereby implementing one possible approach for supporting ISO C feature test macros. Recall that, as described in <https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these macros work based on the definition when affected headers are included, so cannot be handled once when the first system header is included because that might not be one of the headers the particular macro in question affects. <https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses views on possible approaches for implementation and <https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows up on that. This patch arranges things so that the relevant condition is __GLIBC_USE (LIB_EXT2), following one of the suggestions given. Headers using these macros include <bits/libc-header-start.h>, which in turn includes <features.h>. Headers must define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including <bits/libc-header-start.h>, to discourage inclusion outside glibc as requested. __USE_GNU conditions on affected functions are changed to __GLIBC_USE (LIB_EXT2), while it's added as an additional alternative on the conditions for functions already enabled for some POSIX versions. It would be possible to convert existing __USE_* conditionals to __GLIBC_USE (with the relevant __GLIBC_USE_* being defined in <features.h> where __USE_* are presently defined), and so make them typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE is used with #if not #ifdef / #if defined. No attempt is made to enforce the rule about diagnosing different definitions of __STDC_WANT_LIB_EXT2__ when affected headers are included; such a diagnostic is incompatible with multiple-include guards on the affected headers, unless compiler extensions are added to support it. As previously noted, glibc does not implement all features from TR 24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline are not in glibc, although they would be appropriate to add if someone wished to do so. But I think it makes sense to support the feature test macro if *any* of the controlled features are present in glibc. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h: New file. * Makefile (headers): Add bits/libc-header-start.h. * include/features.h (__STDC_WANT_LIB_EXT2__): Document.

* x86_64: Call finite scalar versions in vectorized log, pow, exp (bz #20033).Andrew Senkevich2016-08-0226-58/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vector math functions require -ffast-math which sets -ffinite-math-only, so it is needed to call finite scalar versions (which are called from vector functions in some cases). Since finite version of pow() returns qNaN instead of 1.0 for several inputs, those inputs are excluded for tests of vector math functions.

* malloc: Preserve arena free list/thread count invariant [BZ #20370]Florian Weimer2016-08-022-5/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | It is necessary to preserve the invariant that if an arena is on the free list, it has thread attach count zero. Otherwise, when arena_thread_freeres sees the zero attach count, it will add it, and without the invariant, an arena could get pushed to the list twice, resulting in a cycle. One possible execution trace looks like this: Thread 1 examines free list and observes it as empty. Thread 2 exits and adds its arena to the free list, with attached_threads == 0). Thread 1 selects this arena in reused_arena (not from the free list). Thread 1 increments attached_threads and attaches itself. (The arena remains on the free list.) Thread 1 exits, decrements attached_threads, and adds the arena to the free list. The final step creates a cycle in the usual way (by overwriting the next_free member with the former list head, while there is another list item pointing to the arena structure). tst-malloc-thread-exit exhibits this issue, but it was only visible with a debugger because the incorrect fix in bug 19243 removed the assert from get_free_list.
* alpha: fix trunc for big input valuesAurelien Jarno2016-08-023-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alpha specific version of trunc and truncf always add and subtract 0x1.0p23 or 0x1.0p52 even for big values. This causes this kind of errors in the testsuite: Failure: Test: trunc_towardzero (0x1p107) Result: is: 1.6225927682921334e+32 0x1.fffffffffffffp+106 should be: 1.6225927682921336e+32 0x1.0000000000000p+107 difference: 1.8014398509481984e+16 0x1.0000000000000p+54 ulp : 0.5000 max.ulp : 0.0000 Change this by returning the input value when its absolute value is greater than 0x1.0p23 or 0x1.0p52. NaN have to go through the add and subtract operations to get possibly silenced. Finally remove the code to handle inexact exception, trunc should never generate such an exception.

* sparc: remove ceil, floor, trunc sparc specific implementationsAurelien Jarno2016-08-0247-2245/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ceil, floor and trunc functions on sparc do not fully follow the standard and trigger an inexact exception when presented a value which is not an integer. Since glibc 2.24 this causes a few tests to fail, for instance: testing double (without inline functions) Failure: ceil (lit_pi): Exception "Inexact" set Failure: ceil (-lit_pi): Exception "Inexact" set Failure: ceil (min_subnorm_value): Exception "Inexact" set Failure: ceil (min_value): Exception "Inexact" set Failure: ceil (0.1): Exception "Inexact" set Failure: ceil (0.25): Exception "Inexact" set Failure: ceil (0.625): Exception "Inexact" set Failure: ceil (-min_subnorm_value): Exception "Inexact" set Failure: ceil (-min_value): Exception "Inexact" set Failure: ceil (-0.1): Exception "Inexact" set Failure: ceil (-0.25): Exception "Inexact" set Failure: ceil (-0.625): Exception "Inexact" set I tried to fix that by using the same strategy than used on other architectures, that is by saving the FSR register at the beginning and restoring it at the end of the function. When doing so I noticed a comment that this operation might be very costly, so I decided to do some benchmarks. The benchmarks below represent the time required to run each of the function 60 millions of times with different input value. I have done that in the basic V9 code, the VIS2 code, and using the default C implementation of the libc, for both sparc32 and sparc64, on a Niagara T1 based machine and an UltraSparc IIIi. Given I don't have access to a more recent machine), I haven't been able to test the VIS3 version. Also it should be noted that it doesn't make sense to do this benchmark for V8 or earlier as in that case we use the default C implementation. The results are available in the table below, the "+ fix" version correspond to the one saving and restoring the FSR.

On the UltraSparc IIIi the float version on sparc32 is also faster. Coming back about the fix saving and restoring the FSR, it appears it has a big impact as expected. In that case the C implementation is always faster than the fixed implementations. This patch therefore removes the sparc specific implementations in favor of the generic ones.

* S390: Do not clobber r13 with memcpy on 31bit with copies >1MB.Stefan Liebler2016-07-202-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | If the default memcpy variant is called with a length of >1MB on 31bit, r13 is clobbered as the algorithm is switching to mvcle. The mvcle code returns without restoring r13. All other cases are restoring r13. If memcpy is called from outside libc the ifunc resolver will only select this variant if running on machines older than z10. Otherwise or if memcpy is called from inside libc, this default memcpy variant is called. The testcase timezone/tst-tzset is triggering this issue in some combinations of gcc versions and optimization levels. This bug was introduced in commit 04bb21ac93e90d7696bcaf8febe2b2dd2d83585a and thus is a regression compared to former glibc 2.23 release. This patch removes the usage of r13 at all. Thus it is not saved and restored. The base address for execute-instruction is now stored in r5 which is obtained after r5 is not needed anymore as 256byte block counter. ChangeLog: * sysdeps/s390/s390-32/memcpy.S (memcpy): Eliminate the usage of r13 as it is not restored in mvcle case.

| | | | | | | | | | | | | | | | | | | | During the sincos consolidation I made two mistakes, one was a logical error due to which cos(0x1.8475e5afd4481p+0) returned sin(0x1.8475e5afd4481p+0) instead. The second issue was an error in negating inputs for the correct quadrants for sine.

* Don't install the internal header grp-merge.hZack Weinberg2016-07-182-1/+5
| | | | | | | | | | | | | | | | | | grp-merge.h was introduced in Stephen Gallagher's patch adding the "group merging" feature to NSS. It declares two functions, __copy_grp and __merge_grp, both of which are tagged 'internal_function', which means that nobody can even compile the contents of the header without access to libc-symbols.h, which is not installed. (Also, these functions are GLIBC_PRIVATE exports from libc.so.) Hence I believe grp-merge.h should not be installed either. This really needs to be in 2.24, so that no released version of the library installs this header. I hope that what I did to the ChangeLog diff will allow it to be applied without hassle. * grp/Makefile: Don't install the internal header grp-merge.h.

Since the inline asm statement only passes long, which is 32-bit for x32, in registers, 64-bit off_t is truncated to 32-bit on x32. Since __ASSUME_PREADV and __ASSUME_PWRITEV are defined unconditionally, these syscalls can be implemented in syscalls.list to pass 64-bit off_t in one 64-bit register. Tested on x86-64 and x32 with off_t > 4GB on pread64/pwrite64 and preadv64/pwritev64. [BZ #20348] * sysdeps/unix/sysv/linux/x86_64/syscalls.list: Add pread64, preadv64, pwrite64 and pwritev64.

* [AArch64] Add bits/hwcap.h for aarch64 linuxSzabolcs Nagy2016-07-111-0/+34

* [AArch64] Fix libc internal asm profiling codeSzabolcs Nagy2016-07-113-2/+41
| | | | | | | | | | | | | | | | | | | | | When glibc is built with --enable-profile, the ENTRY of asm functions includes CALL_MCOUNT for profiling. (matters for binaries static linked against libc_p.a.) CALL_MCOUNT did not save/restore argument registers around the _mcount call so it clobbered them. (it is enough to only save/restore the arguments passed to a given asm function, but that would be too many asm changes so it is simpler to always save all argument registers in this macro.) float args are not saved: mcount does not clobber the float regs and currently no asm function takes float arguments anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The p{read,write}v{64} consolidation patch [1] added a wrong guard for LO_HI_LONG definition. It currently uses both '__WORDSIZE == 64' and 'defined __ASSUME_WORDSIZE64_ILP32' to set the value to be passed in one argument, otherwise it will be split in two. However it fails on MIPS64n32 where syscalls n32 uses the compat implementation in the kernel meaning the off_t arguments are passed in two separate registers. GLIBC already defines a macro for such cases (__OFF_T_MATCHES_OFF64_T), so this patch uses it instead. Checked on x86_64, i686, x32, aarch64, armhf, and s390. * sysdeps/unix/sysv/linux/sysdep.h [__WORDSIZE == 64 || __ASSUME_WORDSIZE64_ILP32] (LO_HI_LONG): Remove guards. * misc/tst-preadvwritev-common.c: New file. * misc/tst-preadvwritev.c: Use tst-preadvwritev-common.c. * misc/tst-preadvwritev64.c: Use tst-preadwritev-common.c and add a check for files larger than 2GB.

* Remove __ASSUME_OFF_DIFF_OFF64 definitionAdhemerval Zanella2016-07-0810-9/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the __ASSUME_OFF_DIFF_OFF64 define introduced in p{read,write} consolidation patch. This define was added based on the idea 32 bits ports would continue to follow previous off{64}_t definition where off_t size differs from off64_t one. However, with recent AArch64/ILP32 patch submission and also with discussion for RISCV kernel interface, 32 bits ports now may aim to use off_t and off64_t with the same size as 64 bits. So current assumption for both p{read,write} and p{read,write}v are not compatible with new type definition. This patch now makes the syscall wrappers to only depend on __OFF_T_MATCHES_OFF64_T to define the default and 64-suffix variant, as follow: <function>.c #ifndef __OFF_T_MATCHES_OFF64_T /* build <function> */ #endif and <function>64.c /* build <function>64 */ #ifdef __OFF_T_MATCHES_OFF64_T weak_alias (fallocate64, fallocate) #endif Tested on x86_64, i686, x32, and armhf. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_OFF_DIFF_OFF64): Remove define. * sysdeps/unix/sysv/linux/pread.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pread): Replace by __OFF_T_MATCHES_OFF64_T. * sysdeps/unix/sysv/linux/pread64.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pread64): Likewise. * sysdeps/unix/sysv/linux/preadv.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (preadv): Likewise. * sysdeps/unix/sysv/linux/preadv64.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (preadv64): Likewise. * sysdeps/unix/sysv/linux/pwrite.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwrite): Likewise. * sysdeps/unix/sysv/linux/pwrite64.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwrite64): Likewise. * sysdeps/unix/sysv/linux/pwritev.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwritev): Likewise. * sysdeps/unix/sysv/linux/pwritev64.c [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwritev64): Likewise.
* Add pretty printers for the NPTL lock typesMartin Galvan2016-07-0824-1/+2438
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds pretty printers for the following NPTL types: - pthread_mutex_t - pthread_mutexattr_t - pthread_cond_t - pthread_condattr_t - pthread_rwlock_t - pthread_rwlockattr_t To load the pretty printers into your gdb session, do the following: python import sys sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers') end source /path/to/glibc/source/pretty-printers/nptl-printers.py You can check which printers are registered and enabled by issuing the 'info pretty-printer' gdb command. Printers should trigger automatically when trying to print a variable of one of the types mentioned above. The printers are architecture-independent, and were manually tested on both the gdb CLI and Eclipse CDT. In order to work, the printers need to know the values of various flags that are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since replicating these constants in the printers file itself would create a maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses to extract the constants. This script is pretty much the same as gen-as-const.awk, except it doesn't cast the constant values to 'long' and is thorougly documented. The constants need only to be enumerated in a .pysym file, which is then referenced by a Make variable called gen-py-const-headers. As for the install directory, I discussed this with Mike Frysinger and Siddhesh Poyarekar, and we agreed that it can be handled in a separate patch, and it shouldn't block merging of this one. In addition, I've written a series of test cases for the pretty printers. Each lock type (mutex, condvar and rwlock) has two test programs, one for itself and other for its related 'attributes' object. Each test program in turn has a PExpect-based Python script that drives gdb and compares its output to the expected printer's. The tests run on the glibc host, which is assumed to have both gdb and PExpect; if either is absent the tests will fail with code 77 (UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper. I've tested the printers on both a native build and a cross build using a Beaglebone Black, with the build system's filesystem shared with the board through NFS. Finally, I've written a README that explains all this and more. Hopefully this should be good to go in now. Thanks.
