Thiemo, could you share what the native 3.4 compiler reports as its configuration? (e.g. the "Configured with: " statement)?
 
Thanks,
Eric

Yes, it appears to me that the compiler (cc1) and assembler (as)
invocations are the same. I've included the "-v" output of each
below for reference. Furthermore, the -save-temps output .i files
are effectively the same (differences due to cross vs. native paths,
but that is it). Nonetheless, the output assembly source still
contains differences!

I'm curious if anybody examined the output of a cross and native
toolchain of the same (recent) version?

I get the same (properly optimised) result from both compilers:

  gcc (GCC) 4.1.2 20060901 (prerelease) (Debian 4.1.1-13)
  mips-linux-gnu-gcc (GCC) 4.1.2 20060901 (prerelease) (Debian 4.1.1-13)


I haven't tried a 3.4 crosscompiler, but the native one also behaves
as expected:

  gcc-3.4 (GCC) 3.4.6 (Debian 3.4.6-4)
