ghc --make HelloWorld.hs -optc-mcpu=ultrasparc
then ghc would call gcc to compile .c -> .s with -mcpu=ultrasparc and so generate sparc V9 instructions. But when it came to assembling the .s file, we've not passed the abi flag via -opta so it defaults to the minimum abi. Then of course the assembler bumps into sparc V9 instructions but it had only been told to expect sparc V8 and so it complains.
So I'd suggest building a test file with -split-objs and -v and see exactly what flags ghc is passing to gcc at the compilation and assembly stages.
ok, my gcc is called with mcpu=v9. So "ghc -split-objs" works now with either -optc-mcpu=v8 or -opta-mcpu=v9 (or even -opta-mcpu=ultrasparc). Where should I place what so that my stage1 inplace-compiler works without "SplitObjs=NO" in mk/build.mk?
