howarth at bromo dot med.uc.edu changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |howarth at bromo dot med.uc.edu --- Comment #1 from howarth at bromo dot med.uc.edu --- It appears that Polly in llvm is only coded for isl libraries containing the newer isl_schedule_constraints_compute_schedule() call without fallback support for the older isl_union_set_compute_schedule() call. If we want to support isl 0.12.2 as well as 0.14, we could add a test for the presence of isl_union_set_compute_schedule() to config/isl,m4 and use that to set define in auto-host.h that could be leveraged in gcc/graphite-optimize-isl.c to determine which code path to use.
