Bug ID: 57229
Summary: 4.6/4.7/4.8 inconsistent check for
PRE_MODIFY/POST_MODIFY in post_reload
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization

Proposed fix.
I have found an inconsistency in postreload.c: move2add_note_store(). While
reload_combine_note_store() has been fixed to deal with PRE_MODIFY/POST_MODIFY
in PR 47008 this change is missing for move2add_note_store(). This actually may
lead to wrong code for the msp430 arch (which currently is not yet officially
supported). But I think the code should be fixed anyway to avoid any surprise
when some arch is triggering it. See the attached fix.
