Bug ID: 58271
Summary: ICE in gcc for a MIPS target during compilation with
-mpaired-single -ftree-vectorize
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: niva at niisi dot msk.ru
Created attachment 30721
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30721&action=edit
Preprocessed source file
Running
mips64-none-elf-gcc-4.8.0 mips-ps-7.i -O2 -mpaired-single -ftree-vectorize -S
-o mips-ps-7.s
produces the following ICE:
mips-ps-7.i:1:0: warning: the 'mips3' architecture does not support
paired-single instructions [enabled by default]
extern float a[], b[], c[];
^
mips-ps-7.i: In function 'foo':
mips-ps-7.i:8:10: internal compiler error: in mips_allocate_fcc, at
config/mips/mips.c:4675
a[i] = b[i] == c[i] + 1 ? b[i] : c[i];

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
The cross-compiler was configured as follows:
/home/niva/src/gcc-4.8.0/configure --target=mips64-none-elf --with-threads
--without-headers --disable-libssp --enable-languages=c
--prefix=/home/niva/local
The preprocessed input file is attached.
mips64-none-elf-gcc-4.7.3 also produces an ICE on this test.
IMHO gcc should just disable -mpaired-single for the architectures which do not
support it.

Thanks for the report and sorry for the slow reply. I agree we should
disable -mpaired-single here.
