* patch from paul eggert to fix -0.0/0.0 confusion that breaks glibcPaul Eggert1997-11-131-0/+7
| | | | | | | | | | | | | * real.h (REAL_VALUES_IDENTICAL): New macro. * expr.c (is_zeros_p): Don't consider -0.0 to be all zeros. * fold-const.c (operand_equal_p): Don't consider -0.0 to be identical to 0.0. * tree.c (simple_cst_equal): Don't consider -0.0 to have the same tree structure as 0.0. * varasm.c (immed_real_const_1): Use new REAL_VALUES_IDENTICAL macro instead of doing it by hand. From-SVN: r16472

* If REAL_ARITHMETIC is defined or if LONG_DOUBLE_TYPE_SIZE is 96...Richard Stallman1993-03-311-14/+139
| | | | | | | | | | | | | | | If REAL_ARITHMETIC is defined or if LONG_DOUBLE_TYPE_SIZE is 96, then define REAL_VALUE_ macros to invoke functions in real.c. (REAL_VALUE_RNDZINT, REAL_VALUE_UNSIGNED_RNDZINT): New macros truncate toward zero to integer value but return REAL_VALUE_TYPE. (REAL_VALUE_TO_DECIMAL): New macro defaults to fprintf if no REAL_ARITHMETIC, otherwise uses real.c for binary to decimal conversion. Used in ASM_OUTPUT_ macros. From-SVN: r3934
