Bug ID: 62301
Summary: PowerPC bootstrap broken since r214654
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: wschmidt at gcc dot gnu.org
CC: rdsandiford at googlemail dot com
Host: powerpc64le-unknown-linux-gnu
Target: powerpc64le-unknown-linux-gnu
Build: powerpc64le-unknown-linux-gnu
Bootstrap is failing in stage 2 for powerpc64le-unknown-linux-gnu (and likely
in powerpc64-unknown-linux-gnu as well, though I have not yet confirmed this).
I've bisected the start of the failure to r214654:

* rtl.h (get_pool_constant, rtx_referenced_p): Replace rtx parameters
with const_rtx parameters.
* varasm.c (get_pool_constant): Likewise.
* rtlanal.c (rtx_referenced_p_1): Delete.
(rtx_referenced_p): Use FOR_EACH_SUBRTX instead of for_each_rtx.
Assert that the rtx we're looking for is nonnull. Allow searches
for constant pool SYMBOL_REFs.
Many compiles fail while building libgcc, all segfaulting:
/home/wschmidt/gcc/gcc-mainline-base/libgcc/libgcc2.c: In function '__ashlti3':
/home/wschmidt/gcc/gcc-mainline-base/libgcc/libgcc2.c:454:1: internal compiler
error: Segmentation fault
}
^
xgcc: internal compiler error: Segmentation fault (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
I'll try to get more information in the morning.
