sb0: yes.
nengel_ is now known as nengel
sj_mackenzie has joined #m-labs
<stekern>
sb0: is that specific for or1k gcc?
<sb0>
stekern, nah, seems to be a system-level problem that cannot be blamed on gcc alone
<stekern>
ok, I was mostly thinking about 'if (!cond) {while(!cond);}' though
<stekern>
or was that related to the system-level problem too?
<sb0>
hmm, not sure about that one
<sb0>
I haven't looked at the generated code in detail, just noticed it was faster when ran. it may or may not be the result of a complex cache/dram/whatever interaction...
<sb0>
and the speedup is small.
<stekern>
yeah, but it's still interesting that it's a difference. I would have expected that if to be folded, and the resulting asm to be identical
<stekern>
(and that to happen before any backend code kicks in)
