Kyle R Dunn updated HAWQ-399:
-----------------------------
Description: Currently the crc32c.c file contains GCC-specific
{code}#pragma GCC target ("sse4.2"){code} - the Clang/LLVM equivalent is to add
{code}__attribute__((target("sse4.2"))){code} above the function. This change
allows HAWQ to be compiled with the Clang/LLVM toolchain in addition to GCC.
