From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/other/i386-4.C | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/g++.dg/other/i386-4.C (limited to 'gcc/testsuite/g++.dg/other/i386-4.C') diff --git a/gcc/testsuite/g++.dg/other/i386-4.C b/gcc/testsuite/g++.dg/other/i386-4.C new file mode 100644 index 000000000..858a3a74e --- /dev/null +++ b/gcc/testsuite/g++.dg/other/i386-4.C @@ -0,0 +1,30 @@ +/* { dg-do compile { target i?86-*-* x86_64-*-* } } */ +/* { dg-options "-O1 -msse2" } */ +/* { dg-require-effective-target sse2 } */ + +#include + +void ConvertFloatSSE (void *inBuff, void *outBuff, int len) +{ + unsigned char *inByteBuffer = reinterpret_cast < unsigned char *>(inBuff); + float *outFloatBuffer = reinterpret_cast < float *>(outBuff); + + for (int i = 0; i < len / 4; i++) + { + __m128i register1 = + _mm_set_epi8 (*inByteBuffer, *(inByteBuffer + 1), + *(inByteBuffer + 2), 0, + *(inByteBuffer + 3), *(inByteBuffer + 4), + *(inByteBuffer + 5), 0, + *(inByteBuffer + 6), *(inByteBuffer + 7), + *(inByteBuffer + 8), 0, + *(inByteBuffer + 9), *(inByteBuffer + 10), + *(inByteBuffer + 11), 0); + __m128i register2 = _mm_srai_epi32 (register1, 8); + __m128 register3 = _mm_cvtepi32_ps (register2); + + _mm_store_ps (outFloatBuffer, register3); + outFloatBuffer += 4; + inByteBuffer += 12; + } +} -- cgit v1.2.3
