From: Sebastian Pop Date: Thu, 28 Aug 2014 16:43:55 +0000 (+0000) Subject: check functionality of isl version 0.12 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e0c0c325357ae6b57a5648bdcf1c6af4c0a31572;p=gcc.git check functionality of isl version 0.12 * config/isl.m4 (_ISL_CHECK_CT_PROG): Removed. (ISL_CHECK_VERSION): Check for functionality added to ISL 0.12 instead of checking for version number. * configure: Regenerated. * configure.ac (ISL_CHECK_VERSION): Do not use ISL version number.
