soft-fp: Refactor exception handling for comparisons.
This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro. (_FP_CMP): Add extra argument EX. Call _FP_CMP_CHECK_NAN. (_FP_CMP_EQ): Likewise. (_FP_CMP_UNORD): Likewise. * soft-fp/double.h (FP_CMP_D): Add extra argument EX. (FP_CMP_EQ_D): Likewise.
