These will all be answered with "patches welcome", so a PR doesn't help drive them along. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57630 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/Target/X86/README-UNIMPLEMENTED.txt b/lib/Target/X86/README-UNIMPLEMENTED.txt new file mode 100644 index 00000000000..b9ba4937792 --- /dev/null +++ b/lib/Target/X86/README-UNIMPLEMENTED.txt @@ -0,0 +1,14 @@ +//===---------------------------------------------------------------------===// +// Testcases that crash the X86 backend because they aren't implemented +//===---------------------------------------------------------------------===// + +These are cases we know the X86 backend doesn't handle.
