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

Fixed in r143195. Still it is not "TARGETS" neutral.

In the absense of metadata, it continues to fall back on static heuristics. This allows __builtin_expect, after lowering through llvm.expect a branch instruction's metadata, to actually enter the branch probability model. This is one component of resolving PR2577. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_30@142547 91177308-0d34-0410-b5e6-96231b3b80d8

The implementation layer already had support for printing the results of this analysis, but the wiring was missing. Now that printing the analysis works, actually bring some of this analysis, and the BranchProbabilityInfo analysis that it wraps, under test! I'm planning on fixing some bugs and doing other work here, so having a nice place to add regression tests and a way to observe the results is really useful. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_30@142546 91177308-0d34-0410-b5e6-96231b3b80d8
