x86: Add x86_64 to x86-64 HWCAP [BZ #22093]
|
||||
|
||||
Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the
|
||||
"x86_64" subdirectory when loading a shared library. ld.so in glibc
|
||||
2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based
|
||||
on supported ISAs. This led to shared library loading failure for
|
||||
shared libraries placed under the "x86_64" subdirectory.
|
||||
|
||||
This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always
|
||||
search the "x86_64" subdirectory when loading a shared library.
|
||||
|
||||
NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip
|
||||
the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi"
|
||||
machines.
|
||||
|
||||
Tested on i686 and x86-64.
|
||||
|
||||
[BZ #22093]
|
||||
* sysdeps/x86/cpu-features.c (init_cpu_features): Initialize
|
||||
GLRO(dl_hwcap) to HWCAP_X86_64 for x86-64.
|
||||
* sysdeps/x86/dl-hwcap.h (HWCAP_COUNT): Updated.
|
||||
(HWCAP_IMPORTANT): Likewise.
|
||||
(HWCAP_X86_64): New enum.
|
||||
(HWCAP_X86_AVX512_1): Updated.
|
||||
* sysdeps/x86/dl-procinfo.c (_dl_x86_hwcap_flags): Add "x86_64".
|
||||
* sysdeps/x86_64/Makefile (tests): Add tst-x86_64-1.
|
||||
(modules-names): Add x86_64/tst-x86_64mod-1.
|
||||
(LDFLAGS-tst-x86_64mod-1.so): New.
|
||||
($(objpfx)tst-x86_64-1): Likewise.

($(objpfx)x86_64/tst-x86_64mod-1.os): Likewise.
|
||||
(tst-x86_64-1-clean): Likewise.

||||
* sysdeps/x86_64/tst-x86_64-1.c: New file.
|
||||
* sysdeps/x86_64/tst-x86_64mod-1.c: Likewise.
