             Bug #: 52372
           Summary: gcc.target/mips/mips16-attributes{,-4}.c SEGV in
                    dwf_regno
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
                CC: rsandifo@gcc.gnu.org
              Host: mips-sgi-irix6.5
            Target: mips-sgi-irix6.5
             Build: mips-sgi-irix6.5


The mips16-attributes{, -4}.c tests ICE on IRIX 6:

FAIL: gcc.target/mips/mips16-attributes-4.c (internal compiler error)
FAIL: gcc.target/mips/mips16-attributes-4.c (test for excess errors)
FAIL: gcc.target/mips/mips16-attributes.c (internal compiler error)
FAIL: gcc.target/mips/mips16-attributes.c (test for excess errors)

In the first case, I find:

/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/mips/mips16-attributes-4.c:
In function 'bar':
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/mips/mips16-attributes-4.c:9:1:
internal compiler error: Segmentation fault

The failure boils down to

$ cc1 -fpreprocessed mips16-attributes-4.i -quiet -mabi=o64 -mlong32 -mno-synci
-o mips16-attributes-4.s

In gdb,I see

Program received signal SIGSEGV, Segmentation fault.

I didn't easily see how to find the equivalent of REGNO(reg) in dwf_regno.
