Bug ID: 61487
Summary: LTO breaks on mips with wireless-tools 0.29
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: rose.garcia-eggl2fk at yopmail dot com

(no dependencies, so easy to test)
when built with a gcc 4.8.3 linux crosscompiler plus -flto, i get:
mips-linux-musl-gcc -L/media/3T/x-prefix/mips/lib -isystem
/media/3T/x-prefix/mips/include -s -Wl,--gc-sections -Wl,-z,relro,-z,now -flto
-static -Wl,-s -D_GNU_SOURCE -D_BSD_SOURCE -fdata-sections -ffunction-sections
-Os -g0 -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack
-ftree-dce -s -Os -flto -MMD -o iwlist iwlist.o libiw.a -lm
lto1: internal compiler error: in read_cgraph_and_symbols, at lto/lto.c:2935
(the crosscompiler is built from the musl-cross project, current tip as of
today, using musl 1.1.1; but my guess is that this would happen with other
libcs as well)
