Summary: sparc-rtems does not build
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: joel@gcc.gnu.org
As of yesterday's SVN, gcc is very broken for sparc-rtems. The generated gcc
can't even compile a simple autoconf probe. I would expect that sparc-elf is
similarly broken. This was built with a native built from the same source.
That reports
gcc (GCC) 4.7.0 20110510 (experimental) [trunk revision 173623]
This is from config.log. Let me know what else I can provide.

This is -msoft-float though. Again recent IRA changes I'm afraid...

Vlad, this is an abort in setup_pressure_classes which apparently is totally
broken for sparc -msoft-float.

I found the wrong code. It is pretty simple but I need to check a few
platforms because the fix might affect other platform builds.
I hope I'll send the patch at the end of the day.

SPARC ICC register presents in ALL_REGS class only which can not be a pressure
class. That is the reason for the problem. I also found a typo in the check
code (it collected hard registers of all non-pressure classes although it
should collect the pressure classes hard registers). I found more complication
with the check code in MIPS target. So it took more time than I did.
Currently I am testing the patch and submit it for approval soon.

* ira.c (setup_pressure_classes): Don't check register move cost
for classes with one registers. Don't add pressure class if there
is a pressure class with the same available hard registers.
Check contains_reg_of_mode. Fix a typo in collecting
temp_hard_regset. Ignore hard registers not belonging to a class.
