A configuration with such functions sets float64x-alias-fcts = yes in a sysdeps Makeconfig file; until such settings are added, this test support is inactive. Tested for x86_64, including in conjunction with _Float64x support patches. Committed. 2017-11-24 Joseph Myers * math/test-float64x.h: New file. * math/Makefile (type-float64x-yes): New variable. (test-types): Add $(type-float64x-$(float64x-alias-fcts)). diff --git a/math/Makefile b/math/Makefile index b2bd3d3..668c283 100644 --- a/math/Makefile +++ b/math/Makefile @@ -126,9 +126,14 @@ type-float-routines := k_rem_pio2f math_errf e_exp2f_data e_logf_data \ type-float128-suffix := f128 type-float128-routines := t_sincosf128 k_sincosf128 type-float128-yes := float128 + +# _Float64x may be supported, only as an alias type. +type-float64x-yes := float64x + types = $(types-basic) $(type-float128-$(float128-fcts)) test-types = $(test-types-basic) $(type-float128-$(float128-fcts)) \ - $(type-float128-$(float128-alias-fcts)) + $(type-float128-$(float128-alias-fcts)) \ + $(type-float64x-$(float64x-alias-fcts)) # For each of the basic types (float, double, long double), replace the # occurrences of 'F' in arg 1 with the appropriate suffix for the type. diff --git a/math/test-float64x.h b/math/test-float64x.h new file mode 100644 index 0000000..4ff72ac --- /dev/null +++ b/math/test-float64x.h @@ -0,0 +1,43 @@ +/* Common definitions for libm tests for _Float64x. + + Copyright (C) 2017 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
