To a previous problem I've asked, Andrew Pinski replied that I should
merge all *movsi patterns into a single one to avoid (in that case)
strange deletions in the generated assembly. Is that possible here? It
appears to me that I would need the ability to differentiate the
different patterns using constraints, but is there a way to define
custom versions of the 'm' pattern? I didn't find anything on that in
the documentation. Did I miss something?
Thanks a bunch,

Andras,
The whole point of benchmarks is to judge a processor's performance.
That being said, just crippling GCC is not reasonable because
processors must be judged in the appropriate context and that

That's true, I did notice GCC being rather ... peculiar about
drhystone. Is there a way to make it less clever about the benchmark?
Or is there some alteration to the benchmark I can make to not trigger
the special behavior in GCC?

Thanks H-P! I'll certainly check it out.

As a test to narrow the problem down, I removed the 'emit_jump_insn'
call above. That generated an assembly (thus proving the theory that the
assert has something to do with that), but then the assembly doesn't
contain my label, only a reference to it; which of course later on would
result in a linker error.
So, what am I doing wrong and how can I achieve what I want?
Thank you all wise sages!

This is quite possibly not enough information for anyone to figure this
out, so please tell me what else should I include to make things more
clear?
Thanks a lot!

Thanks for the help, that's exactly it!
