Subject: [PATCH] [BZ #10118]

2009-05-06  Ryan S. Arnold  <rsa@us.ibm.com>
	[BZ #10118]
	* Makeconfig (+asflags): New variable based upon ASFLAG or
	asflags-cpu.
	(ASFLAGS): Add override to set ASFLAGS to +asflags.
	* config.make.in (asflags-cpu): Add variable based upon
	@libc_cv_cc_submachine@ to propagate -mcpu=CPU from --with-cpu=CPU to
	the assembler.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/setcontext.S:
	Remove unneeded file now that the assembler emits _ARCH_PWR6 and
	recognizes power6 instruction set due to passing -mcpu=power6 from
	--with-cpu=power6 when compiling .S files.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/swapcontext.S:
	Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/setcontext.S:
	Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/swapcontext.S:
	Likewise.
