Subject: [Bug target/62281] gcc doesn't conform to Solaris 32-bit ABI by expecting 16-byte stack alignment
Date: Fri, 29 Aug 2014 15:16:00 -0000	[thread overview]
Message-ID: <bug-62281-4-grY3PPHbHN@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #7 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
FWIW, I recommended to Sun in Mar 2006 that the kernel should ensure 
16-byte alignment for both signal handlers and process startup (apparently 
this resulted in Sun bug 6397812, "Problem with stack alignment for signal 
delivery on AMD64").  (This does not of course mean that the ABI ended up 
with such an alignment requirement at interface boundaries in general.)
