From e5277ba25dc0665f192ebc3f9649a00098dbdc9e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 28 Nov 2016 23:27:23 +0000 Subject: Make ilogb wrappers type-generic. This patch converts the ilogb wrappers (which set errno directly rather than doing anything with __kernel_standard) to use the type-generic template machinery. This is intended as preparation for adding llogb. Tested for x86_64 and x86, and tested compile for other architectures with build-many-glibcs.py. * math/w_ilogb_template.c: New file. Based on math/w_ilogb.c. * math/w_ilogb.c: Remove. * math/w_ilogbf.c: Likewise. * math/w_ilogbl.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_ilogb.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_ilogbl.c: Likewise. * math/Makefile (gen-libm-calls): Add w_ilogbF. (libm-calls): Remove w_ilogbF. * sysdeps/ieee754/ldbl-opt/math-type-macros-double.h (LDOUBLE_ilogbl_libm_version): New macro. --- math/Makefile | 3 +-- math/w_ilogb.c | 42 ------------------------------------------ math/w_ilogb_template.c | 42 ++++++++++++++++++++++++++++++++++++++++++ math/w_ilogbf.c | 38 -------------------------------------- math/w_ilogbl.c | 38 -------------------------------------- 5 files changed, 43 insertions(+), 120 deletions(-) delete mode 100644 math/w_ilogb.c create mode 100644 math/w_ilogb_template.c delete mode 100644 math/w_ilogbf.c delete mode 100644 math/w_ilogbl.c (limited to 'math') diff --git a/math/Makefile b/math/Makefile index 7196e5e..bcf627d 100644 --- a/math/Makefile +++ b/math/Makefile @@ -52,7 +52,7 @@ gen-libm-calls = cargF conjF cimagF crealF cabsF s_cacosF \ k_casinhF s_csinhF k_casinhF s_csinhF s_catanhF s_catanF \ s_ctanF s_ctanhF s_cexpF s_clogF s_cprojF s_csqrtF \ s_cpowF s_clog10F s_fdimF s_nextdownF s_fmaxF s_fminF \ - s_nanF s_iseqsigF s_canonicalizeF + s_nanF s_iseqsigF s_canonicalizeF w_ilogbF libm-calls = \ e_acosF e_acoshF e_asinF e_atan2F e_atanhF e_coshF e_expF e_fmodF \ @@ -67,7 +67,6 @@ libm-calls = \ w_atan2F w_atanhF w_coshF w_expF w_exp2F w_exp10F w_fmodF \ w_tgammaF w_hypotF w_j0F w_j1F w_jnF w_lgammaF w_lgammaF_r \ w_logF w_log10F w_powF w_remainderF w_scalbF w_sinhF w_sqrtF \ - w_ilogbF \ s_fpclassifyF s_truncF \ s_remquoF e_log2F e_exp2F s_roundF s_nearbyintF s_sincosF \ s_fmaF s_lrintF s_llrintF s_lroundF s_llroundF e_exp10F w_log2F \ diff --git a/math/w_ilogb.c b/math/w_ilogb.c deleted file mode 100644 index 3bbe5ec..0000000 --- a/math/w_ilogb.c +++ /dev/null @@ -1,42 +0,0 @@ -/* Copyright (C) 2012-2016 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Adhemerval Zanella , 2011. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
