Summary: gcc forces 16-byte stack alignment on Solaris i386,
when SYSV requires word alignment
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: y...@tsoft.com
Linux made a decision to switch to 16-byte alignment, but not others.
I know for a fact that Solaris is affected, I am not sure, but FreeBSD i386
might also be affected.
Please turn this behavior back to the one prescribed by specification for
Solaris (and FreeBSD if affected):
http://www.sco.com/developers/devspecs/abi386-4.pdf
section 3-10: "The stack is word aligned. Although the architecture does not
require any alignment of the stack, software convention and the operating
system requires that the stack be aligned on a word boundary."
Or please refer to the Sun/Oracle decision to change this behavior.
