From 16a25138c13c9d687a9bc2b130e1aea4d26257b7 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 22 Aug 2018 12:25:50 +0000 Subject: Move ROUNDING_TESTS_* out of math-tests.h. Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the ROUNDING_TESTS_* macros for individual types out to their own sysdeps header. In the soft-float case where FE_TONEAREST is the only rounding mode macro defined, there is no need to define ROUNDING_TESTS_*; it is only necessary when rounding modes macros are defined that may not be supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some configurations are just removed, not moved to new math-tests-rounding.h headers; the only architectures needing math-tests-rounding.h are those where the macros are defined in bits/fenv.h because of the possibility of a soft-float compilation using a hard-float glibc with the same ABI (i.e., ARM and RISC-V). The test-*-vlen*.h headers, by using #undef, do not yet follow typo-proof conventions (but they no longer implicitly rely on being included before math-tests.h, and this area can always be cleaned up further in future).
