From 29c4dfd92edc26c2cd2c0c64c9201d5b91d6418e Mon Sep 17 00:00:00 2001 From: Chris Zankel Date: Thu, 31 May 2007 17:49:32 -0700 Subject: [XTENSA] Remove non-rt signal handling The non-rt signal handling was never really used, so we don't break anything. This patch also cleans up the signal stack-frame to make it independent from the processor configuration. It also improves the method used for controlling single-stepping. We now save and restore the 'icountlevel' register that controls single stepping and set or clear the saved state to enable or disable it.
