I am trying to understand the role of cmm files in the current GHC compiler build process (I am guessing, they have replaced .hc files like PrimOps and AutoApply). They are compiled by the stage1 compiler. Is ability to compile cmm preserved in the compiler finally built at stage3 and installed? What compiler flags are available for cmm files compilation? The User's guide says nothing specific. Are -E, -C, -S available (along with -c and -fvia-c seen in the nightly build log)? -- Dimitry Golubovsky Anywhere on the Web
