X-Git-Tag: glibc-2.16-tps~369
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=842b81d6113b45c9a10a93dd8415639c414df946;p=platform%2Fupstream%2Fglibc.git

Mark sparc %fsr load and store inline asms as volatile.

	* sysdeps/sparc/fpu/bits/fenv.h (__fenv_stfsr): Add __volatile__.
	* sysdeps/sparc/fpu/fpu_control.h (_FPU_GETCW):	Likewise.
