Hello,
when working on ARM port I've noticed that when LLVM's llc tool provides
nicely formated error message for more than one line then GHC does not
print all the lines out to the error output but just forgets them. This is
bad IMHO since having it printed all the info is needed in case of the
LLVM's errors I got: this was full backtrace of assert inside llc -- very
helpful for debugging of what's going on. Also such assert was easily
solved later by just adding proper -optlc= option to be passed to LLVM
llc. So this is not just for new port developers, but will probably also
helps general GHC audience, i.e. GHC users on platform where LLVM is used.
