[Q] CMM error (cross-powerpc-linux backend)

[Gabor Greif]

Hi hackers,

I got my cross-ghc so far that it compiles its own libraries, now onto the rts!

All goes right, until I get:

"inplace/bin/ghc-stage1"   -H64m -O0 -fasm -Iincludes -Irts
-Irts/dist/build -DCOMPILING_RTS -package-name rts  -dcmm-lint      -i
-irts -irts/dist/build -irts/dist/build/autogen -Irts/dist/build
-Irts/dist/build/autogen        -optc-DCOMPILING_GHC    -optc-O2   -c
rts/Apply.cmm -o rts/dist/build/Apply.o
Cmm lint error:
  in proc stg_AP_STACK_entry
    in basic block c2g
      in assignment:
        _c21::I32 = I64[_c20::I32 + 4 + 8];
        Reg ty: I32
        Rhs ty: I64


For some reason I64 appears but that should be avoided in the
powerpc-linux backend :-(
My --host is x86_64-linux, so it may creep in from there.

So my question, which include I should look at? I am pretty newbie with CMM.

Cheers and thanks,

    Gabor


PS: include/ghcautoconf.h (almost) looks good:
