Looking closer into the gcc.target/mips/interrupt_handler-[23].c
failures
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \\t\\\\.cfi_restore
64\\n
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \\t\\\\.cfi_restore
65\\n
and many more for interrupt_handler-3.c, I now understand what's going
on: .cfi* directives are only emitted if dwarf2cfi.c
(dwarf2out_do_cfi_asm) returns true, but if MIPS_DEBUGGING_INFO is
defined (as is the case in iris6.h), it returns false. Thus, the tests
are meaningless since even the scan-assembler-not tests only succeed
because no .cfi* directives whatsoever are present in the assembler
output. XFAILing them with dg-xfail-if doesn't work:
XPASS: gcc.target/mips/interrupt_handler-2.c (test for excess errors)
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \t\\.cfi_restore 64\n
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \t\\.cfi_restore 65\n
and adding xfail's to each and every dg-final seems pointless,
especially given that the scan-assembler-not tests only pass by
accident. I therefore just skip the tests on IRIX.
Tested with the appropriate runtest invocation on mips-sgi-irix6.5,
installed on mainline.
