Hi,
In the past few days, something has regressed
on the sparc. Revision 169143 only had 699 failures
and ~100 of those were LTO related. David Korn's
patch seems to have resolved those. Revision 169504
has 2231 failures.
Were you able to test whether or not the ira-costs.c patch was the cause
of these problems? It's been problematical elsewhere and it wouldn't
take much more than a nudge to for me to pull it given its ability to
uncover latent problems.
This is for revision 169231. So it looks like that caused
the failures.
OK. I'm going to take a looksie. As long as it isn't something I've
already fixed or some dumb bug elsewhere, the plan is to pull the
ira-costs patch and revisit it in stage1.
If you need me to test something, just yell.
Will do.
What's the best way to test the sparc-rtems target? Do you use a sim?
I've got access to sparcs via the gcc buildfarm, but that's about it.
We use the sis/erc32 simulator in gdb.
You have to build binutils, gdb, gcc/newlib, and rtems
to be able to test. I am happy to help you offline
with setting it up. But it is probably quicker for
you to send me a patch and let me push it through
the (smaller than GCC's) RTEMS build farm. :)
