* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): If

bit_AVX is set also check OSXAVE/XCR0 and reset bit_AVX if necessary.

|
||||
|
||||
Really fix AVX tests
|
||||
|
||||
There is no problem with strcmp, it doesn't use the YMM registers.
|
||||
The math routines might since gcc perhaps generates such code.
|
||||
Introduce bit_YMM_USBALE and use it in the math routines.
|
||||
|
||||
[BZ #13583]
|
||||
* sysdeps/x86_64/multiarch/init-arch.h: Define bit_OSXSAVE.
|
||||
Clean up HAS_* macros.
|
||||
* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): If
|
||||
bit_AVX is set also check OSXAVE/XCR0 and set bit_YMM_Usable if
|
||||
possible.
|
||||
* sysdeps/x86_64/fpu/multiarch/e_atan2.c: Use HAS_YMM_USABLE, not
|
||||
HAS_AVX.
