Hi all, Recently Richard showed us how to load GHC into CHCi which ended up being documented here: https://ghc.haskell.org/trac/ghc/wiki/Debugging/Compiler That very useful for some things, but doesn't give you access to symbols and types that have not been exported. Specifically, I'm interested in some of the inner workings of the file `compiler/llvmGen/LlvmCodeGen.hs` and I've even managed to load it into GHCi using the command line: inplace/bin/ghc-stage2 --interactive -ignore-dot-ghci -fobject-code \ -DSTAGE=1 -i -icompiler/basicTypes -icompiler/cmm -icompiler/codeGen \ -icompiler/coreSyn -icompiler/deSugar -icompiler/ghci -icompiler/hsSyn \ -icompiler/iface -icompiler/llvmGen -icompiler/main -icompiler/nativeGen \ -icompiler/parser -icompiler/prelude -icompiler/profiling -icompiler/rename \ -icompiler/simplCore -icompiler/simplStg -icompiler/specialise -icompiler/stgSyn \ -icompiler/stranal -icompiler/typecheck -icompiler/types -icompiler/utils \ -icompiler/vectorise -icompiler/stage1/build -icompiler/stage1/build/autogen \ -Icompiler/stage1/build -Icompiler/stage1/build/autogen -Icompiler/. \ -Icompiler/parser -Icompiler/utils -Icompiler/stage1 -XHaskell2010 \ compiler/llvmGen/LlvmCodeGen.hs and it loads all the modules require, but then seems to mess up the symbol table so that it can't even find top level functions in the module it has just loaded. Prelude LlvmCodeGen> :t LlvmCodeGen.cmmDataLlvmGens <interactive>:1:1: error: Not in scope: ‘LlvmCodeGen.cmmDataLlvmGens’ No module named ‘LlvmCodeGen’ is imported. I even tied adding `-icompiler/llvmGen` to the above command line (from hell) before I noticed that it was already present. Anyone have any idea why this doesn't work?
