I'm pretty it's the following that causes bootstrap to fail for me:
2014-06-29 Roman Gareev <gareevroman@gmail.com>
* Makefile.in:
Add the compilation of graphite-isl-ast-to-gimple.o.
* common.opt:
Add new switch fgraphite-code-generator=[isl|cloog].
* flag-types.h:
Add new enum fgraphite_generator.
* graphite-isl-ast-to-gimple.c: New.
* graphite-isl-ast-to-gimple.h: New.
* graphite.c (graphite_transform_loops):
Add choice of Graphite code generator,
which depends on flag_graphite_code_gen.
testsuite/gcc.dg/graphite/isl-codegen-loop-dumping.c:
New testcase that checks that the dump is generated.
As follows:
/scratch2/tmp/gerald/gcc-HEAD/gcc/graphite-isl-ast-to-gimple.c:23:10:
fatal error: 'isl/set.h' file not found
#include <isl/set.h>
^
I do not have ISL installed on that machine and I don't want to use
graphite on that machine.
PR 61650 - [4.10] Bootstrap failure due to dependency on ISL.
Hi Gerald,
sorry for the breakage. This seems to be caused by forgotten include
guards. I attached a patch (not bootstrapped yet), that should fix the
issue. I will start a gcc (non-graphite) bootstrap to see if it works
and will commit it immediately after.
Please report back if it fixes the bootstrap for you.
Cheers,
Tobias
