* Add libm_alias_finite for _finite symbolsWilco Dijkstra2020-01-031-1/+2
| | | | | | | | | | | | | | | | | | | This patch adds a new macro, libm_alias_finite, to define all _finite symbol. It sets all _finite symbol as compat symbol based on its first version (obtained from the definition at built generated first-versions.h). The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need special treatment in code that is shared between long double and float128. It is done by adding a list, similar to internal symbol redifinition, on sysdeps/ieee754/float128/float128_private.h. Alpha also needs some tricky changes to ensure we still emit 2 compat symbols for sqrt(f). Passes buildmanyglibc.

* ldbl-128: Use L(x) macro for long double constantsPaul E. Murphy2016-09-131-70/+70
| | | | | | | | | | | | | | | | | | | | This runs the attached sed script against these files using a regex which aggressively matches long double literals when not obviously part of a comment. Likewise, 5 digit or less integral constants are replaced with integer constants, excepting the two cases of 0 used in large tables, which are also the only integral values of the form x.0*E0L encountered within these converted files. Likewise, -L(x) is transformed into L(-x). Naturally, the script has a few minor hiccups which are more clearly remedied via the attached fixup patch. Such hiccups include, context-sensitive promotion to a real type, and munging constants inside harder to detect comment blocks.
* ldbl-128: Rename 'long double' to '_Float128'Paul E. Murphy2016-08-311-4/+4
| | | | | | | | | | | | | | | | | | Add a layer of macro indirection for long double files which need to be built using another typename. Likewise, add the L(num) macro used in a later patch to override real constants. These macros are only defined through the ldbl-128 math_ldbl.h header, thereby implicitly restricting these macros to machines which back long double with an IEEE binary128 format. Likewise, appropriate changes are made for the few files which indirectly include such ldbl-128 files. These changes produce identical binaries for s390x, aarch64, and ppc64.
* Fix ldbl-128/ldbl-128ibm acosl inaccuracy (bug 18038, bug 18039).Joseph Myers2015-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of acosl have similar bugs, using a threshold of 0x1p-57L to determine when they just return pi/2. Since the result pi/2 - asinl (x) is roughly pi/2 - x for small x, the relevant cut-off is actually x being < 0.5ulp of 1. This patch fixes the implementations to use that cut-off and adds tests of small acos arguments. Tested for powerpc and mips64. Also tested for x86_64 and x86; no ulps updates needed.
