Bug ID: 66697
Summary: Feature request: -mstackrealign and
force_align_arg_pointer for x86_64
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: bucaneer at gmail dot com
Target Milestone: ---
-mstackrealign option and force_align_arg_pointer attribute work for 32bit x86,
but not x86_64.
In particular, this makes Wine unable to deal with some untidy 64bit Windows
apps: https://bugs.winehq.org/show_bug.cgi?id=27680
