Bug ID: 80433
Summary: [CRIS] ICE at -O2: unrecognized insn (post_inc on acr)
building glibc sha512.c
Product: gcc
Version: 7.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: gcc at davidrobins dot net
Target Milestone: ---
Created attachment 41202
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41202&action=edit
Preprocessed sha512.c from glibc.
Compiling attached preprocessed glibc (2.9) sha512.c as:
crisv32-linux-gnu-gcc sha512.i -S -O2 -o sha512.S
results in:
sha512.c: In function _sha512_process_block_:
sha512.c:206:1: error: unrecognizable insn:
}

No error at lower optimization levels.
I have also attached the .271r.ira and .272r.reload pass output files.
