Subject: [PATCH] __THROW in libio revisited
Date: Fri, 30 Mar 2007 11:41:00 -0000 [thread overview]
Message-ID: <20070330114616.GE1826@sunsite.mff.cuni.cz> (raw)
Hi!
The following functions either directly call cancellation points (usually open,
write, read) or can call it indirectly.
This patch itself doesn't fix BZ#2748, but together with building involved
objects with -fexceptions it would. While I think I prefer just compiling
whole glibc with -fasynchronous-unwind-tables which doesn't actually require
the __THROW removal (except on exported functions), IMHO nuking __THROW
even just for documentation purposes that a function is a possible
cancellation point is a good idea.
