Description

Extended Description

While attempting to compile a C file generated by GHC. llvm-gcc chocked with the error message "sorry, unimplemented: LLVM cannot register variable 'R1'." and requested I report a bug.

The GHC version was ghc-6.8.3.

From the root of the GHC installation the path to the header llvm-gcc was parsing is "include/Regs.h" and the error occured at line 220.
