All,
Thanks for all the help from the past. I'm (still) working on porting
GCC to a new processor ISA and ran into the following problem: the CPU
supports two kinds of register+offset based loads (and stores).
The generic format accepts any base register and any offset. The syntax
for this type o
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?

Hello all!
I'm working on porting GCC to a new processor architecture. I think
I've finally got to a fairly stable stage, so the next logical step
would be to test and optimize. For that, I would need some benchmarks,
and this is where I'm seeking your help.
This being a hobby project, I can't sh

All,
I'm working on porting GCC to a processor architecture that doesn't have
a (HW) stack nor a call instruction. This means that for calls, I need
to generate the following instruction sequence:
// move stack-pointer:
$sp <- $sp-4
// load return address:
$r3 <- return_label

All!
I'm trying to port GCC to a new target, I call 'brew'. I've based it on
the Moxie target mostly because of it's simplicity.
I must be doing something horribly wrong as the following C code crokes
in the LRA path:
long long foo (long long a, long long *w)
{
return __builtin_add_ov
Thanks for the help, that's exactly it!

What I'm working on is to port GCC (and Binutils) to a new CPU ISA, I
call 'brew'. During developing for th
