The ISL version we download from download_prerequesites on the GCC 6 branch (0.15) has a trailing comma at the end of an enumerator list. This causes GCC 4.3.4 to error as we are compiling with -pedantic (GCC 4.4 and up just warn). The following fixes this bootstrap issue by patching the ISL sources after downloading them. Tested on SLE11 SP4 with GCC 4.3.4 host compiler (where I also reproduced the issue). As we control ftp://gcc.gnu.org/pub/gcc/infrastructure/isl-0.15.tar.bz2 the sed expression is quite simplistic. Ok for the GCC 6 branch? I hope mv can reliably overwrite the destination on all supported hosts (not sure if -f is portable). I can use cp as well, of course. I hope && outside of 'if' is portable as well. Thanks, Richard. 2016-08-17 Richard Biener <rguent...@suse.de> * download_prerequisites: Patch ISL 0.15 to remove trailing comma which causes PR77297.
Seems reasonable to me. Jeff
