Justin Bogner 6484f6de8c InstrProf: Do a better job of reading coverage mapping data. ... This code was casting regions of a memory buffer to a couple of different structs. This is wrong in a few ways: 1. It breaks aliasing rules. 2. If the buffer isn't aligned, it hits undefined behaviour. 3. It completely ignores endianness differences. 4. The structs being defined for this aren't specifying their padding properly, so this doesn't even represent the data properly on some platforms. This commit is mostly NFC, except that it fixes reading coverage for 32 bit binaries as a side effect of getting rid of the mispadded structs. I've included a test for that. I've also baked in that we only handle little endian more explicitly, since that was true in practice already. I'll fix this to handle endianness properly in a followup commit. llvm-svn: 232346		2015-03-16 06:55:45 +00:00
