Right, the process is roughly this: 1: compile stage 1 GHC (with the libraries and RTS of the compiler we already have) 2: compile the RTS with the stage 1 GHC 3: compile the libraries with the stage 1 GHC 4: compile a stage 2 GHC with the stage 1 GHC, and the RTS and libraries that we built with it except older GHCs don't have all the libraries we'd like to use to write GHC, so there's actually a step 0: 0: compile the libraries in compat/ with the compiler we already have and these compat libraries are also used in step 1. > So when I look for symbols mentioned in the RTS stack, (e.g., > "s311_info") I have > to refer to the -ddump-stg output from the ghc-6.4.2 build. Is this > true? That and the compat/ of the new GHC tree. If your 6.4.2 is still the hc-build then s311_info should be in the .hc files if it's from there.
