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 for32 bit binaries as a side effect of getting rid of the mispaddedstructs. 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 handleendianness properly in a followup commit.llvm-svn: 232346 List of files: /llvm-project-15.0.7/llvm/test/tools/llvm-cov/Inputs/binary-formats.proftext Mon, 16 Mar 2015 06:55:45 +0000 Justin Bogner <mail@justinbogner.com>
