Bug ID: 71698
Summary: ICE related to decimal float when compiling with
-mcpu=power9
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: acsawdey at gcc dot gnu.org
CC: dje at watson dot ibm.com, segher at gcc dot gnu.org,
wschmidt at linux dot vnet.ibm.com
Target Milestone: ---
There are a number of these that fell out when running a make check with
-mcpu=power9. The common pattern seems to involve decimal float and looks like
this:
