Bug ID: 66822
Summary: Turn off X86_TUNE_ZERO_EXTEND_WITH_AND for IAMCU
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
CC: julia.koval at intel dot com
Target Milestone: ---
Since X86_TUNE_ZERO_EXTEND_WITH_AND generates bigger code, should
it be turned off for IAMCU?

Agreed, this is basically the same issue as core issue 1430 for alias templates. We can fix the crash on this testcase by adding concepts to the DR 1430 check in coerce_template_parms, but complain is tf_none at that point so we don't get a helpful error message. Any thoughts on that? It seems to me that we probably want to pass complain through the normalize/lift functions.
