This fixes PR54458 where DOM jump threading turns a loop into

Hello!
The x86 cpuid instruction returns a processor ID and the
__get_cpuid_max function even explicitly makes the %ebx value directly
available. But users of that function have to use a cryptic constant.
How about adding a few macros to make this more transparent?
There are some other
While examining the Power MD file seeking the explanation for a problem I
saw I have noticed a change in the past separated one of the instruction
splitters from its corresponding instruction pattern. Several unrelated
patterns were inserted between the two, presumably by accident where the

That also allows you to handle (say) mipsisa32-mti-linux-gnu vs.
mipsisa64-mti-linux-gnu.

Sure, if there are still people using those they can easily add those.

OK, thanks.
I don't have commit access (or at least I'm not on the write after

Hi,
I've added a libjava unittest which verifies that this patch will not
break Java debug info. I've also incorporated Richard's review in the
previous mail. Attached is the new patch, which passed bootstrap and
all gcc/libjava testsuites on x86.
Is it ok for trunk?
Thanks,
Dehao
The attached patch improves the cost estimate for multiplication, etc,
on parisc. It was noted debugging various PRs that the cost for multiplication
of long longs was seriously underestimated.
Tested on hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11 and hppa-unknown-linux-gnu.
Committed to trunk.
