Subject: * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: Use
X-Git-Tag: upstream/2.30~13772
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1454da21955742494232aa8b34c5e238263ad37a;p=external%2Fglibc.git

* sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: Use

	.machine push; .machine "power6" and .machine pop around mtfsf
	insns outside of _ARCH_PWR6 define.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S:
	Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S:
	Likewise.
	* sysdeps/powerpc/fpu/tst-setcontext-fpscr.c (_SET_DI_FPSCR): Likewise.
	* sysdeps/powerpc/fpu/fenv_libc.h (fesetenv_register,
	relax_fenv_state): Likewise.
