From c7b1f30258f6dbf26705d86343b8cd402376cb70 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Thu, 6 Aug 2020 10:18:10 +0200 Subject: [PATCH] Remove std::map use from graphite This replaces the use of std::map with hash_map for mapping ISL ids to SSA names. 2020-08-06 Richard Biener * graphite-isl-ast-to-gimple.c (ivs_params): Use hash_map instead of std::map. (ivs_params_clear): Adjust. (gcc_expression_from_isl_ast_expr_id): Likewise. (graphite_create_new_loop): Likewise. (add_parameters_to_ivs_params): Likewise. --- gcc/graphite-isl-ast-to-gimple.c | 30 +++++++++++------------------- 1 file changed, 11 insertions(+), 19 deletions(-) diff --git a/gcc/graphite-isl-ast-to-gimple.c b/gcc/graphite-isl-ast-to-gimple.c index 81f7b48887c..5fa70ff2d4e 100644 --- a/gcc/graphite-isl-ast-to-gimple.c +++ b/gcc/graphite-isl-ast-to-gimple.c @@ -24,7 +24,6 @@ along with GCC; see the file COPYING3.
