From eb29c3e1fab9f985144fd4d63f5b86c039c459d0 Mon Sep 17 00:00:00 2001 From: Andrew MacLeod Date: Fri, 9 Jun 2023 13:25:49 -0400 Subject: Unify NE_EXPR range operator Move the declaration of the class to the range-op-mixed header, add the floating point prototypes as well, and use it in the new unified table. * range-op-float.cc (foperator_not_equal): Remove. Move prototypes to range-op-mixed.h (operator_equal::fold_range): Rename from foperator_not_equal. (operator_equal::op1_range): Ditto. (float_table::float_table): Remove NE_EXPR. * range-op-mixed.h (class operator_not_equal): Combined from integer and float files. * range-op.cc (op_equal): New object. (unified_table::unified_table): Add NE_EXPR. (class operator_not_equal): Move to range-op-mixed.h. (not_equal_op1_op2_relation): Fold into operator_not_equal::op1_op2_relation. (integral_table::integral_table): Remove NE_EXPR. (pointer_table::pointer_table): Remove NE_EXPR. * range-op.h (not_equal_op1_op2_relation): Delete. --- gcc/range-op-float.cc | 36 +++++++++--------------------------- gcc/range-op-mixed.h | 29 +++++++++++++++++++++++++++++ gcc/range-op.cc | 41 ++++++++++------------------------------- gcc/range-op.h | 1 - 4 files changed, 48 insertions(+), 59 deletions(-) diff --git a/gcc/range-op-float.cc b/gcc/range-op-float.cc index 98636ce..ec24167 100644 --- a/gcc/range-op-float.cc +++ b/gcc/range-op-float.cc @@ -675,28 +675,10 @@ operator_equal::op1_range (frange &r, tree type, return true;
