Subject: asm-x86/sigcontext.h changes break userland
Date: Tue, 12 Feb 2008 19:15:32 -0500 [thread overview]
Message-ID: <20080213001532.GJ24887@devserv.devel.redhat.com> (raw)
Hi!
The
x86: use generic register names in struct sigcontext
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=742fa54a62be6a263df14a553bf832724471dfbe
changeset breaks userland, e.g. it is not possible to compile gcc anymore
(both 32-bit and 64-bit libgcc), and I expect any other program which pokes
into struct sigcontext. The register names with e resp. r have been in use
for years, what's the point breaking it now?
Jakub
