Subject: [Buildroot] [PATCH] package/gcc: fix ICE on xtensa, 5.x and 6.x, PR target/78603
Date: Tue, 29 Nov 2016 15:37:49 -0800 [thread overview]
Message-ID: <1480462669-19677-1-git-send-email-jcmvbkbc@gmail.com> (raw)
Zero overhead loop optimization pass may incorrectly put start of the
loop between a call and its CALL_ARG_LOCATION note, resulting in the
following build error:
../src/pjlib-test/thread.c: In function 'thread_test':
../src/pjlib-test/thread.c:328:1: internal compiler error: in
dwarf2out_var_location, at dwarf2out.c:21846
Fixes:
