Hi all,
You can turn on e.g. SSE 4.1 by passing -msse4.2 to ghc. This doesn't currently imply that we compile any C code with -msse4.2 turned on, so if someone really want to use SSE4.2, they have to do:
ghc -msse4,2 -optc-msse4.2
Do we want to change this so it's enough to pass -msse4.2 to ghc?
+1, I'd expect the flag to affect all compiled code (I'd be passing -msse4.2 to make it go faster). If anyone really wanted the C code to be compiled without (perhaps for debugging the code generator), they could run something like: ghc -msse4,2 -optc-no-msse4.2 Conrad.
