Description Erik Schnetter 2005-11-10 17:14:00 UTC 
I checked out gcc from svn; I have version

$ svn info

I configured with

CFLAGS='-g -O2 -mlongcall' CXXFLAGS='-g -O2 -mlongcall' /Users/eschnett/src/gcc/configure --prefix=/Users/eschnett/gcc --with-mpfr=/Users/eschnett --disable-multilib --enable-languages=c,c++,fortran,java,objc,treelang

and then built with

make bootstrap

This aborts with the error message

Failing assembler output

This is from a different invokation of the compiler, i.e., the auto-generated file name is different from the one in the error message.
Comment 3 Andrew Pinski 2005-11-10 17:32:42 UTC 
Something is really wrong:
        beq- cr7,_L13070


There should be no underscore there.

Some get it correct:
        b L12781

What gcc are you starting with?
What happens if you remove -mlongcall from the CFLAGS?

Mine.  I'll try to get the failure with a cross compiler.
