x86: Move STATE_SAVE_OFFSET/STATE_SAVE_MASK to sysdep.h
|
||
|
|
|
||
|
|
Move STATE_SAVE_OFFSET and STATE_SAVE_MASK to sysdep.h to make
|
||
|
|
sysdeps/x86/cpu-features.h a C header file.
|
||
|
|
|
||
|
|
* sysdeps/x86/cpu-features.h (STATE_SAVE_OFFSET): Removed.
|
||
|
|
(STATE_SAVE_MASK): Likewise.
|
||
|
|
Don't check __ASSEMBLER__ to include <cpu-features-offsets.h>.
|
||
|
|
* sysdeps/x86/sysdep.h (STATE_SAVE_OFFSET): New.
|
||
|
|
(STATE_SAVE_MASK): Likewise.
|
||
|
|
* sysdeps/x86_64/dl-trampoline.S: Include <cpu-features-offsets.h>
|
||
|
|
instead of <cpu-features.h>.
