In addition to the totalorder functions, TS 18661-1 defines totalordermag functions, which do the same comparison but on the absolute values of the arguments. This patch implements these functions for glibc, including the type-generic macro in <tgmath.h>. In general the implementations are similar to but simpler than those for the totalorder functions. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (totalordermag): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (totalordermag): New macro. * math/Versions (totalordermag): New libm symbol at version GLIBC_2.25. (totalordermagf): Likewise. (totalordermagl): Likewise. * math/Makefile (libm-calls): Add s_totalordermagF. * math/libm-test.inc (totalordermag_test_data): New array. (totalordermag_test): New function. (main): Call totalordermag_test. * math/test-tgmath.c (NCALLS): Increase to 125. (F(compile_test)): Call totalordermag. (F(totalordermag)): New function. * manual/arith.texi (FP Comparison Functions): Document totalordermag, totalordermagf and totalordermagl. * manual/libm-err-tab.pl: Update comment on interfaces without ulps tabulated. * sysdeps/ieee754/dbl-64/s_totalordermag.c: New file. * sysdeps/ieee754/dbl-64/wordsize-64/s_totalordermag.c: Likewise. * sysdeps/ieee754/flt-32/s_totalordermagf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-opt/nldbl-totalordermag.c: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile (libnldbl-calls): Add totalordermag.
