From 139ef32b0e6b88b00b5e3e74d052d938f178dc9b Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 7 Jun 2010 08:48:13 -0400 Subject: Revert adding some arch-specific signal syscalls to . It turns out there is some variance on the calling conventions for these syscalls, and is already the mechanism used to handle this. Switch arch/tile over to using that mechanism and tweak the calling conventions for a couple of tile syscalls to match .
