clang14 assert on PtrTy->isOpaqueOrPointeeTypeMatches(IRFuncTy) #54950

Open Kurkin opened 2 years ago

Kurkin commented 2 years ago

I tried to migrate to the clang14 and got the following error on link stage with thin lto

ld.gold-2.38: fatal error: LLVM gold plugin: Explicit call type does not match pointee type of callee operand (Producer: 'LLVM14.0.0' Reader: 'LLVM 14.0.0')

and this crash with full lto

I believe this was fixed by 45084eab5e6, @aeubanks can you please confirm? I think this fix should be merged to release/14.x

Ah no, it still asserts in the same way with quite recent 5c9f3ec4ad5 (llvmorg-15-init-11439-g5c9f3ec4ad5) and -no-opaque-pointers (which got enabled in 702d5de4380b1e1554e5b90863093c3a57f76f70 by @nikic):

Further minimized:
