Don't assume APInt::getRawData() would hold target-aware endianness nor host-compliant endianness. rawdata[0] holds most lower i64, even on big endian host. FIXME: Add a testcase for big endian target. FIXME: Ditto on CompileUnit::addConstantFPValue() ? ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_30@143449 91177308-0d34-0410-b5e6-96231b3b80d8

(Specifically, don't insert an arbitrary instruction before a PHI.)

------------------------------------------------------------------------ r143006 | stoklund | 2011-10-25 18:47:48 -0700 (Tue, 25 Oct 2011) | 8 lines Don't use floating point to do an integer's job. This code makes different decisions when compiled into x87 instructions because of different rounding behavior. That caused phase 2/3 miscompares on 32-bit Linux when the phase 1 compiler was built with gcc (using x87), and the phase 2 compiler was built with clang (using SSE). This fixes PR11200. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_30@143013 91177308-0d34-0410-b5e6-96231b3b80d8
