Bug ID: 59460
Summary: [4.9 Regression] ICE with -mips16 and
__attribute__((nomips16))
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: robert.suchanek at imgtec dot com
Target: mips16
A number of failures started to appear on the trunk for mips-elf target
(possibly other targets too) and all of the new failures are related
to the fix for PR58115. The following is a narrowed testcase that triggers
an ICE.
It crashes when attributes for a function try to override -mips16 argument
given on the commandline. I found another problem with the testcase when the
function takes an argument of type v2sf: the compiler segfaults due to
recursive calls, but this also points to the fix.
$ cat mips-ps-2.c
typedef float v2sf __attribute__ ((vector_size(8)));
__attribute__((nomips16)) v2sf foo () {}
$ mips-elf-gcc -mips32r2 -mfp64 -mips16 -mpaired-single -c mips-ps-2.c
mips-ps-2.c: In function âfooâ:
mips-ps-2.c:3:1: internal compiler error: in emit_move_multi_word, at
expr.c:3518
__attribute__((nomips16)) v2sf foo () {}
