[llvm-commits] CVS: llvm-test/SingleSource/UnitTests/Vector/SSE/sse.expandfft.c sse.stepfft.c

[Reid Spencer]

Changes in directory llvm-test/SingleSource/UnitTests/Vector/SSE:

sse.expandfft.c updated: 1.3 -> 1.4
sse.stepfft.c updated: 1.2 -> 1.3
---
Log message:

Change this program to use the valloc method as _mm_alloc is not present on all
platforms. valloc is overkill, but there's only four such allocations in the
program so it shouldn't cause scalability problems due to page-size allocations
and it will ensure the largest necessary alignment size on any platform.o

This helps the test program compile on Linux.
