> OK for mainline? Yes, this is pretty obvious. (You don't have to change to prev_nondebug_insn btw).
Ayal. From: Revital Eres <revital.e...@linaro.org> To: Ayal Zaks/Haifa/IBM@IBMIL Cc: gcc-patches@gcc.gnu.org, Patch Tracking <patc...@linaro.org> Date: 08/05/2011 07:37 AM Subject: [PATCH, SMS 2/3] Skip DEBUG_INSNs while recognizing doloop Hello, The attached patch adds code to skip DEBUG_INSNs while recognizing doloop pattern. The patch was tested together with the rest of the patches in this series and on top of the patch to support do-loop for ARM (not yet in mainline, but approved http://gcc.gnu.org/ml/gcc-patches/2011-01/msg01718.html). On ppc64-redhat-linux regtest as well as bootstrap with SMS flags enabling SMS also on loops with stage count 1. Regtested on SPU. On arm-linux-gnueabi regtseted on c,c++. Bootstrap c language with SMS flags enabling SMS also on loops with stage count 1. OK for mainline?
