This looks like a mangler or a splitter problem (those manky Perl
scripts we use to postprocess assembly code). Probably gcc 3.4.3 is
generating something we don't recognise.
Could you try the following:
- Add SplitObjs=NO to build.mk, recompile the libraries (make clean
&& make) and try to compile a simple program with the stage1 ghc.
If that works, then it's a splitter problem.
- If you get link errors, then
$ cd libraries/base
$ rm -f GHC/Base.o
$ make GHC/Base.o EXTRA_HC_OPTS='-keep-s-file -keep-raw-s-file'
and send me the contents of GHC/Base.s and GHC/Base.raw_s.
Cheers,
Simon
