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