From: Andrew Macleod <amacleod@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r14-1668] Unify EQ_EXPR range operator Date: Sat, 10 Jun 2023 00:33:39 +0000 (GMT) [thread overview] Message-ID: <20230610003339.B93173857C44@sourceware.org> (raw) https://gcc.gnu.org/g:2dbf1e6146e3f0d6d7b4533ca654ad8c4ee03419 commit r14-1668-g2dbf1e6146e3f0d6d7b4533ca654ad8c4ee03419 Author: Andrew MacLeod <amacleod@redhat.com> Date: Fri Jun 9 13:18:39 2023 -0400 Unify EQ_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_equal): Remove. Move prototypes to range-op-mixed.h (operator_equal::fold_range): Rename from foperator_equal. (operator_equal::op1_range): Ditto. (float_table::float_table): Remove EQ_EXPR. * range-op-mixed.h (class operator_equal): Combined from integer and float files. * range-op.cc (op_equal): New object. (unified_table::unified_table): Add EQ_EXPR. (class operator_equal): Move to range-op-mixed.h. (equal_op1_op2_relation): Fold into operator_equal::op1_op2_relation. (integral_table::integral_table): Remove EQ_EXPR. (pointer_table::pointer_table): Remove EQ_EXPR. * range-op.h (equal_op1_op2_relation): Delete.
