We get an ICE when compiling alsa-lib on s390x.

[sharkcz@devel11 pcm]$ gcc -DHAVE_CONFIG_H -I. -I../../include -I../../include -O2 -g -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -march=zEC12 -mtune=z13 -c pcm_rate_linear.c  -fPIC -DPIC -o .libs/pcm_rate_linear.o
pcm_rate_linear.c: In function ‘linear_expand’:
pcm_rate_linear.c:136:1: internal compiler error: output_operand: cannot decompose address

Comment 1 Dan Horák 2017-05-17 11:36:10 UTC 
It requires both -O2 and -march=zEC12 -mtune=z13 to reproduce.
