Subject: Bug 16921. MMX and SSE2 intrinsics not enabled when compiling with Intel's icc
X-Git-Tag: pixman-0.11.10~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=daf17450607e533dc590b4673c88241862b6b138;p=platform%2Fupstream%2Fpixman.git

Bug 16921. MMX and SSE2 intrinsics not enabled when compiling with Intel's icc

Remove GCC specific inline-growth flags, and use __force_inline__ in
pixman-sse2 instead. Based on patch by Matt Turner.
