* Y2038: make __difftime compatible with 64-bit timeAlbert ARIBAUD (3ADEV)2018-12-203-9/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a 64-bit-time version of __difftime (but do not assume __time64_t is a signed int so that Gnulib can reuse the code) and make the 32-bit version a wrapper of it. Current difftime expects two time_t arguments and returns a double. To preserve source-code compatibility, its 64-bit-time equivalent expects two __time64_t arguments but still returns a double. This patch was tested by running 'make check' on branch master then applying this patch and its two predecessors and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. This patch was also functionally tested with an ad hoc userland C program which checks the result of difftime for various pairs of 32-bit and, for 64-bit builds, of 64-bit time_t values too. The program was built and run against a glibc with and without the patch, and the results compared to ensure the patch does not change the behavior of difftime. * include/time.h (__difftime64): Add. * time/difftime.c (subtract): convert to 64-bit time. * time/difftime.c (__difftime64): Add. * time/difftime.c (__difftime): Wrap around __difftime64.

* Remove x86 mathinline.h.Joseph Myers2018-12-193-295/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Remove x86 mathinline.h sinh, cosh, tanh inlines.Joseph Myers2018-12-192-16/+7
| | | | | | | | | | | | | | | | | | | | | | 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.
* Print cache size and geometry auxv types on LD_SHOW_AUXV=1Tulio Magno Quites Machado Filho2018-12-193-31/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* Remove __ASSUME_ST_INO_64_BIT.Joseph Myers2018-12-188-43/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

* S390: Cleanup ifunc-resolve.h.Stefan Liebler2018-12-187-41/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ifunc macros s390_vx_libc* are no longer used and can be removed as all users are now relying on s390_libc_ifunc_expr. The same applies to s390_libc_ifunc. The macro s390_libc_ifunc_init is now renamed to s390_libc_ifunc_expr_stfle_init and the users are adjusted accordingly. ChangeLog: * sysdeps/s390/multiarch/ifunc-resolve.h (s390_vx_libc_ifunc, s390_vx_libc_ifunc_redirected, s390_vx_libc_ifunc2, s390_vx_libc_ifunc_init, s390_vx_libc_ifunc2_redirected, s390_libc_ifunc): Delete macro definition. (s390_libc_ifunc_init): Rename to s390_libc_ifunc_expr_stfle_init. * sysdeps/s390/bzero: Use s390_libc_ifunc_expr_stfle_init instead of s390_libc_ifunc_init. * sysdeps/s390/memcmp.c: Likewise. * sysdeps/s390/memcpy.c: Likewise. * sysdeps/s390/mempcpy.c: Likewise. * sysdeps/s390/memset.c: Likewise.
