I haven't found anything in my digging, so I'd like to ask if anyone knows
of any mechanism in GCC for conducting peephole optimization on generated
code. I can imagine doing this as a pass over the generated code from
within the backend, or as a separate process between cc1 and as. I'm
working w
Awesome, thanks Richard!

I have another gcc 4.3 question. I'm trying to find where in the code base
the instrumentation for basic block coverage is done. I've tracked down
where/how mcount() calls are generated, but I haven't even been able to
determine what function(s) are called to increment a basic block's count.
I'd
I'll take a look, Paul, thanks. It hadn't occurred to me to compare
different machines' uses.

Is there anyone on the list with experience with the gcc 4.3 codebase? I'm
currently maintaining a fork of it, with a PDP10 code generator.
I've run into an issue involving the transformation of a movmemhi to a
single PDP10 instruction (an xblt, if you're curious). The transformation
appears to
