Hi,
Trying to build config-list.mk for current trunk.
The box is a stable debian (7.8 it seems) so the OS' ISL is too old
thus i was attempting to use in-tree ISL.
When using an in-tree ISL gcc attempts to determine if it is recent
enough and AFAIU fails to do so since the system's ISL (which we will not use)
might be too old and the in-tree ISL is not yet built.
This results in HAVE_ISL_SCHED_CONSTRAINTS_COMPUTE_SCHEDULE being not
set and thus compilation of graphite-isl-ast-to-gimple.c fails with
"template with C linkage".
The attached seems to get me past compilation of
graphite-isl-ast-to-gimple.c with config-list.mk for e.g.
alpha-linux-gnu
I'm scheduling a proper regstrap on x86_64-linux-gnu for a native
compiler but this will take days to start i fear.
So.. if somebody has spare cycles.. :)
cheers,
