From 48d864a060ae79a809b5dc12c298d1e2e4a29026 Mon Sep 17 00:00:00 2001
From: Richard Biener <rguenther@suse.de>
Date: Thu, 16 Feb 2017 07:53:53 +0000
Subject: [PATCH 5/5] graphite.h: Do not include isl/isl_val_gmp.h, instead
include isl/isl_val.h.
2017-02-16 Richard Biener <rguenther@suse.de>
* graphite.h: Do not include isl/isl_val_gmp.h, instead include
isl/isl_val.h.
* graphite-isl-ast-to-gimple.c (gmp_cst_to_tree): Remove.
(gcc_expression_from_isl_expr_int): Use generic isl_val interface.
* graphite-sese-to-poly.c: Do not include isl/isl_val_gmp.h.
(isl_val_int_from_wi): New function.
(extract_affine_gmp): Rename to ...
(extract_affine_wi): ... this, take a widest_int.
(extract_affine_int): Just wrap extract_affine_wi.
(add_param_constraints): Use isl_val_int_from_wi.
(add_loop_constraints): Likewise, and extract_affine_wi.
