#7049: LLVM backend miscompiles GHC stage2 ---------------------------------+------------------------------------------ Reporter: kgardas | Owner: dterei Type: bug | Status: infoneeded Priority: normal | Milestone: 7.8.1 Component: Compiler (LLVM) | Version: 7.5 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: Building GHC failed Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by kgardas): Hi David, thanks for looking into this old bug, however I'm not able to duplicate this already for some time now. Anyway, I tested on i386-solaris and arm-linux and both were able to build quick-llvm and with arm-linux I've also tested perf-llvm which is IIRC how the bug was found and there is nothing failing. Or better I get to a known failure in ghci which is caused by our not so well ARM support in rts/Linker.c. So please close this. Thanks!

Why did stuff in nativeGen get reverted? we don't support -fasm on these platforms... Any chance we could revert the revert and go with @slyfox's fix?
