Bug ID: 66691
Summary: ICE on valid code at -O3 with -g enabled in
simplify_subreg, at simplify-rtx.c:5744
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: su at cs dot ucdavis.edu
Target Milestone: ---
The following code causes an ICE when compiled with the current gcc trunk at
-O3 with -g enabled on x86_64-linux-gnu in 32-bit mode (but not in 64-bit
mode).
It also affects 5.1.x, thus is a regression from 4.9.x.
$ gcc-trunk -v
