Summary: Bootstrap error with ada with -mcpu=power7
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
CC: meissner at gcc dot gnu.org
Trying to bootstrap gcc (4.8-RH, but reproduced also with the trunk) with
a ppc64 compiler configured --with-cpu=power7 ICEs during stage1 while par.adb
is being compiled at -O0.
Reproduced even with a cross-compiler from x86_64-linux, will attach a tarball
with all the required files.
../gnat1 -I. -gnatwa -quiet -nostdinc -m64 -gnatpg -gnatwns -mtune=power7
-mcpu=power7 par.adb -o /tmp/par.s
par.adb: In function ‘Par’:
par.adb:1604:5: error: insn does not satisfy its constraints:
(insn 1505 719 1504 (set (reg:TI 77 0)
(const_double -16 [0xfffffffffffffff0] 7 [0x7] 0 [0] 0 [0]))
par.adb:1509 721 {*vsx_movti_64bit}
(nil))
