Remove incorrect register mov in floorf/nearbyint on x86_64
|
||
|
|
|
||
|
|
The change in 0b5395f052ee09cd7e3d219af4e805c38058afb5 replaced calls
|
||
|
|
to __get_cpu_features@plt followed by a mov from rax to rdx, with a
|
||
|
|
single macro LOAD_RTLD_GLOBAL_RO_RDX. It is pretty clear that there
|
||
|
|
was a typo in s_floorf and __nearbyint due to which the (now incorrect)
|
||
|
|
mov was not removed. This patch removes that mov.
|
||
|
|
|
||
|
|
* sysdeps/x86_64/fpu/multiarch/s_floorf.S (__floorf): Remove
|
||
|
|
unnecessary movq.
|
||
|
|
* sysdeps/x86_64/fpu/multiarch/s_nearbyint.S (__nearbyint):
|
||
|
|
Likewise.
