The tradeoff of either FTZ or Optimized I think will not work for me.
Find crtfastmath.o in gcc build directory and link it to your final executable.

Yes, gcc-4.4.3 works (it just does not use 'rev' instruction). So it is a
regression in 4.5. Thanks for a very fast response and analysis of the issue.

We're making use of global register variables, which work fine in GCC version
4.3.2 and 4.3.3. GCC 4.4.1 and 4.4.3 however produce slightly different code,
which seems to be incorrect.
A brief example is:
//---test_register_call.c---
register unsigned long long
Compiler output:
$ gcc -mno-sse testcase.c
testcase.c: In function 'foo':
testcase.c:3: error: SSE register return with SSE disabled
