[LLVMdev] Compiling llvm-gcc on amd64 with 32 bits: assembler still carps

[Joachim Durchholz]

Hi all,

I managed to navigate around all those issues with environment variables
and such. llvm itself now builds and checks just fine, but I can't get
llvm-gcc to compile.

Trying to 'make' from .../gcc gives me:

./xgcc -B./ -B/home/jo/i686-pc-linux-gnu/bin/
-isystem /home/jo/i686-pc-linux-gnu/include
-isystem /home/jo/i686-pc-linux-gnu/sys-include

          -o crtbegin.o

./xgcc -dumpmachine gives
i686-pc-linux-gnu
so this is OK.

The reported lines are:
     27         pushl   %ebp
     37         call    *%edx
     55         pushl   %ebp
     65         call    *%eax

What's wrong?

Regards,
Jo

P.S.: I'm running with a freshly compiled and PATH-installed llvm
package with a clean 'make check', and use
