Replace REAL_VALUES_EQUAL with real_equal
Richard B suggested we should replace dconsthalf etc. with dconst<1, 2> (). When I tried that, the extra comma caused problems with some lingering uses of the old target macros for handling reals (e.g. REAL_ARITHMETIC instead of real_arithmetic), since the constant was then treated as two macro parameters. It would have been possible to add an extra level of brackets to avoid this, but I thought I might as well take the opportunity to remove the macros instead. (Note that I'm only removing macros that caused a problem directly, or are closely related to ones that did.) This first patch replaces REAL_VALUES_EQUAL with a real_equal function. The prototype is the same as for real_identical, which has already undergone a half-transition in this direction. Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by building one target per CPU directory and checking that there were no new warnings and no changes in testsuite output at -O2. gcc/c-family/ * c-lex.c (interpret_float): Use real_equal instead of REAL_VALUES_EQUAL. gcc/c/ * c-typeck.c (c_tree_equal): Use real_equal instead of REAL_VALUES_EQUAL. gcc/cp/ * tree.c (cp_tree_equal): Use real_equal instead of REAL_VALUES_EQUAL. gcc/ * real.h (real_equal): Declare.
