2018-12-31riscv: Use __has_include__ to include <asm/syscalls.h> [BZ #24022]H.J. Lu1-1/+5
<asm/syscalls.h> has been removed by commit 27f8899d6002e11a6e2d995e29b8deab5aa9cc25 Author: David Abdurachmanov <david.abdurachmanov@gmail.com> Date: Thu Nov 8 20:02:39 2018 +0100 riscv: add asm/unistd.h UAPI header Marcin Juszkiewicz reported issues while generating syscall table for riscv using 4.20-rc1. The patch refactors our unistd.h files to match some other architectures. - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h - Adjust kernel asm/unistd.h So now asm/unistd.h UAPI header should show all syscalls for riscv. <asm/syscalls.h> may be restored by Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header Date: Tue, 11 Dec 2018 09:09:35 +0100 UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header, which did resolve issue with missing syscalls macros resulting in glibc (2.28) build failure. It also broke glibc in a different way: asm/syscalls.h is being used by glibc. I noticed this while doing Fedora 30/Rawhide mass rebuild. The patch returns asm/syscalls.h header and incl. it into asm/unistd.h. I plan to send a patch to glibc to use asm/unistd.h instead of asm/syscalls.h In the meantime, we use __has_include__, which was added to GCC 5, to check if <asm/syscalls.h> exists before including it. Tested with build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7. [BZ #24022] * sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if <asm/syscalls.h> exists with __has_include__ before including it.

2018-12-21Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers2-0/+3
The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations.

2018-12-19Remove x86 mathinline.h.Joseph Myers2-295/+32
After previous cleanups, the only code in the x86 bits/mathinline.h that is relevant with current compilers is the inline of __ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES (i.e. for when libm itself is being built). This inline is something that does belong in glibc not GCC, since __ieee754_atan2l is a purely internal function name. This patch moves that inline to a new sysdeps/x86/fpu/math_private.h, removing the bits/mathinline.h header. Note that previously the inline was only for non-SSE 32-bit x86. That condition does not make sense, however, for a long double function; if it's not inlined, exactly the same x87 instruction will end up getting used by the out-of-line function, for both 32-bit and 64-bit. So that condition is not retained in the new version. Tested for x86_64 and x86. As expected, installed stripped shared libraries are unchanged for 32-bit x86, but installed stripped libm.so is changed for x86_64 because calls to __ieee754_atan2l start being inlined where previously they were out of line calls. (The same change to start inlining the function would presumably also apply for 32-bit built with -mfpmath=sse, but that's not a configuration I've tested.) * sysdeps/x86/fpu/math_private.h: New file. * sysdeps/x86/fpu/bits/mathinline.h: Remove.
2018-12-19Remove x86 mathinline.h sinh, cosh, tanh inlines.Joseph Myers1-16/+0
Continuing the removal of bits/mathinline.h inlines that would better be done by the compiler, this patch removes x86 inlines for sinh, cosh and tanh functions (inlines only previously present for fast-math, non-SSE 32-bit x86). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such inlines as an optimization in GCC. I believe the only remaining part of the x86 bits/mathinline.h that does anything useful with current compilers after this patch is the __LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to remove the whole header and move that inline to a sysdeps math_private.h header in a subsequent patch. Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline definition. (cosh): Likewise. (tanh): Likewise.
2018-12-19Print cache size and geometry auxv types on LD_SHOW_AUXV=1Tulio Magno Quites Machado Filho1-2/+53
Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when LD_SHOW_AUXV=1. AT_L*_CACHESIZE is printed as decimal and represent the number of bytes of the cache. AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size and its associativity. Example output from a POWER8: AT_L1I_CACHESIZE: 32768 AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L1D_CACHESIZE: 65536 AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L2_CACHESIZE: 524288 AT_L2_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L3_CACHESIZE: 8388608 AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative Some of the new types are longer than the previous ones, requiring to increase the indentation in order to keep the values aligned. * elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY. Fix indentation when printing the other fields. (_dl_show_auxv): Give a special treatment to AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY. * sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function. (_dl_procinfo): Fix indentation when printing AT_HWCAP and AT_HWCAP2. Add support for AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.

2018-12-18alpha: Use Linux generic sigaction implementationAdhemerval Zanella8-115/+22
Alpha rt_sigaction syscall uses a slight different kernel ABI than generic one: arch/alpha/kernel/signal.c 90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act, 91 struct sigaction __user *, oact, 92 size_t, sigsetsize, void __user *, restorer) Similar as sparc, the syscall expects a restorer function. However different than sparc, alpha defines the restorer as the 5th argument (sparc defines as the 4th). This patch removes the arch-specific alpha sigaction implementation, adapt the Linux generic one to different restore placements (through STUB macro), and make alpha use the Linux generic kernel_sigaction definition. Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity). * sysdeps/unix/sysv/linux/alpha/Makefile: Update comment about __syscall_rt_sigaction. * sysdeps/unix/sysv/linux/alpha/kernel_sigaction.h (kernel_sigaction): Use Linux generic defintion.

2018-12-18m68k: Fix sigaction kernel definition (BZ #23960)Adhemerval Zanella7-34/+23
Commit b4a5d26d883 (linux: Consolidate sigaction implementation) added a wrong kernel_sigaction definition for m68k, meant for __NR_sigaction instead of __NR_rt_sigaction as used on generic Linux sigaction implementation.

2018-12-18Remove __ASSUME_ST_INO_64_BIT.Joseph Myers7-43/+0
kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment "However, SH is lame, and still does not have a 64-bit inode field.". The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha case is, however, trivially useless: none of the files that test __ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel support for stat64 syscalls, with a 64-bit st_ino field, in Linux 2.6.4; the define to 0 for Alpha in glibc predates that). The SH kernel gained support for a 64-bit st_ino in struct stat64 in commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64() syscall."), which is in Linux 2.6.22 and later. So the redefinition of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of the files testing it do so immediately after a stat64-family syscall has been used, which will always have set the 64-bit st_ino correctly (in addition to the 32-bit __st_ino), while the relevant code __xstat32_conv executes only after such a syscall in the function calling __xstat32_conv. Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it. Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases around it identical, so that conditional is also removed. Tested compilation with build-many-glibcs.py for its Alpha and SH configurations; also ran the glibc testsuite for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT): Remove macro definition. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_ST_INO_64_BIT): Do not undefine and define. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_ST_INO_64_BIT): Likewise. * sysdeps/unix/sysv/linux/fxstat64.c: Do not include <kernel-features.h>.

2018-12-18S390: Refactor gconv_simple ifunc handling.Stefan Liebler1-11/+12
The ifunc handling for various __gconv_transform_* functions which are using IFUNC on s390x are adjusted in order to omit ifunc if the minimum architecture level already supports newer CPUs by default. Instead those functions are just an alias to the vector variants. Furthermore the ifunc-macro s390_libc_ifunc_expr is now used instead of s390_vx_libc_ifunc. ChangeLog: * sysdeps/s390/multiarch/gconv_simple.c (ICONV_VX_IFUNC): Define macro dependent on HAVE_S390_MIN_Z13_ZARCH_ASM_SUPPORT.

ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove rawmemchr variants. * sysdeps/s390/Makefile (sysdep_routines): Add rawmemchr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for rawmemchr. * sysdeps/s390/multiarch/rawmemchr-c.c: Move to ... * sysdeps/s390/rawmemchr-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/rawmemchr-vx.S: Move to ... * sysdeps/s390/rawmemchr-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/rawmemchr.c: Move to ... * sysdeps/s390/rawmemchr.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-rawmemchr.h: New file.
2018-12-18S390: Refactor memchr ifunc handling.Stefan Liebler10-105/+127
The ifunc handling for memchr is adjusted in order to omit ifunc variants if those will never be used as the minimum architecture level already supports newer CPUs by default. Glibc internal calls will then also use the "newer" ifunc variant. Note: The fallback s390-32/s390-64 ifunc variants with srst instruction are now moved to the unified memchr-z900.S file which can be used for 31/64bit. The s390-32/s390-64 files multiarch/memchr.c and memchr.S are deleted.
