* Add test infrastructure for narrowing libm functions.Joseph Myers2018-02-091-0/+56
This patch continues preparations for adding TS 18661-1 narrowing libm functions by adding the required testsuite infrastructure to test such functions through the libm-test infrastructure. That infrastructure is based around testing for a single type, FLOAT. For the narrowing functions, FLOAT, the "main" type for testing, is the function return type; the argument type is ARG_FLOAT. This is consistent with how the code built once for each type, libm-test-support.c, depends on FLOAT for such things as calculating ulps errors in results but can already handle different argument types (pointers, integers, long double for nexttoward). Makefile machinery is added to handle building tests for all pairs of types for which there are narrowing functions (as with non-narrowing functions, aliases are tested just the same as the functions they alias). gen-auto-libm-tests gains a --narrow option for building outputs for narrowing functions (so narrowing sqrt and fma will share the same inputs as non-narrowing, but gen-auto-libm-tests will be run with and without that option to generate different output files). In the narrowing case, the auto-libm-test-out-narrow-* files include annotations for each test about what properties ARG_FLOAT must have to be able to represent all the inputs for that test; those annotations result in calls to the TEST_COND_arg_fmt macro. gen-libm-test.pl has some minor updates to handle narrowing tests (for example, arguments in such tests must be surrounded by ARG_LIT calls instead of LIT calls). Various new macros are added to the C test support code (for example, sNaN initializers need to be properly typed, so arg_snan_value is added; other such arg_* macros are added as it seems cleanest to do so, though some are not strictly required). Special-casing of the ibm128 format to allow for its limitations is adjusted to handle it as the argument format as well as as the result format; thus, the tests of the new functions allow nonzero ulps only in the case where ibm128 is the argument format, as otherwise the functions correspond to fully-defined IEEE operations. The ulps in question appear as e.g. 'Function: "add_ldouble"' in libm-test-ulps (with 1ulp errors then listed for double and float for that function in powerpc); no support is added to generate corresponding faddl / daddl ulps listings in the ulps table in the manual. For the previous patch, I noted the need to avoid spurious macro expansions of identifiers such as "add". A test test-narrow-macros.c is added to verify such macro expansions are successfully avoided, and there is also a -mlong-double-64 version of that test for ldbl-opt. This test is set up to cover the full set of relevant identifiers from the start rather than adding functions one at a time as each function group is added. Tested for x86_64 (this patch in isolation, as well as testing for various configurations in conjunction with the actual addition of "add" functions). * math/Makefile (test-type-pairs): New variable.
