Subject: [PATCH] [llvm] Avoid linking llvm-cfi-verify to duplicate libs
|
|
|
|
Fix the CMake rules for LLVMCFIVerify library not to pull duplicate
|
|
LLVM .a libraries when linking to the dylib. This prevents problems
|
|
due to duplicate symbols and apparently fixes mingw32.
|
|
|
|
This is an alternative approach to D44650 that just forces .a libraries
|
|
instead. However, there doesn't seem to be any reason to do that.
