[BZ #19058]
|
||
|
|
* math/Makefile ($(inst_libdir)/libm.so): Added libmvec_nonshared.a to
|
||
|
|
AS_NEEDED.
|
||
|
|
* sysdeps/x86/fpu/bits/math-vector.h: Removed code with asm aliases
|
||
|
|
workaround.
|
||
|
|
* sysdeps/x86_64/fpu/Makefile (libmvec-support,
|
||
|
|
libmvec-static-only-routines): Added new file.
|
||
|
|
* sysdeps/x86_64/fpu/svml_finite_alias.S: New file.
|
||
|
|
* NEWS: Mention this fix.
