According to git bisect, this is the root cause of a miscompile for Regex in libLLVMSupport. I am still working on reducing a test case. The actual bug may be elsewhere and this commit just exposed it. Anyway, at the moment, to reproduce, follow these steps: 1. Build clang and libLTO in release mode. 2. Create a new build directory <stage2> and cd into it. 3. Use clang and libLTO from #1 to build llvm-extract in Release mode + asserts using -O2 -flto 4. Run llvm-extract -ralias '.*bar' -S test/Other/extract-alias.ll Result: program doesn't contain global named '.*bar'! Expected result: @a0a0bar = alias void ()* @bar @a0bar = alias void ()* @bar declare void @bar() Note: In step #3, if you don't use lto or asserts, the miscompile disappears. llvm-svn: 259674 |
