Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that they return long int instead of int. Corresponding FP_LLOGB* macros are defined, whose values are required to have the obvious correspondence to those of the FP_ILOGB* macros. This patch implements these functions and macros for glibc. llogb uses the type-generic infrastructure, with an implementation similar to the wrapper for ilogb but with additional conversion from FP_ILOGB* to FP_LLOGB*; this approach avoids needing to modify or duplicate any of the architecture-specific ilogb implementations. Tests are also based on those for ilogb. Ideally the llogb functions would alias the ilogb ones when long is 32-bit, but such aliasing requires the associated header declarations of the different-type alias to be hidden, typically by defining macros before including the header (see e.g. how sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to __hidden_lround before including <math.h>). The infrastructure for type-generic function implementations does not support defining such macros at present (since C code can't define a macro whose name is determined by other macros). So this patch leaves them as separate functions (similar to e.g. scalbln and scalbn being separate in such a case as well), but with the remapping of FP_ILOGB* to FP_LLOGB* conditioned out in the case where it would be the identity map. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New macro. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (__FP_LONG_MAX): New macro.
