Gomes" Date: Thu, 3 Nov 2016 12:37:08 -0200 Subject: float128: Add strfromf128 Add strfromf128 to stdlib when _Float128 support is enabled. * stdio-common/printf-parsemb.c (__parse_one_specmb): Initialize spec->info.is_binary128 to zero. * stdio-common/printf.h (printf_info): Add new member is_binary128 to indicate that the number being converted to string is compatible with the IEC 60559 binary128 format. * stdio-common/printf_fp.c (__printf_fp_l): Add code to deal with _Float128 numbers. * stdio-common/printf_fphex.c: Include ieee754_float128.h and ldbl-128/printf_fphex_macros.h (__printf_fphex): Add code to deal with _Float128 numbers. * stdio-common/printf_size.c (__printf_size): Likewise. * stdio-common/vfprintf.c (process_arg): Initialize member info.is_binary128 to zero. * stdlib/fpioconst.h (FLT128_MAX_10_EXP_LOG): New macro. * stdlib/stdlib.h: Include bits/floatn.h for _Float128 support. (strfromf128): New declaration. * stdlib/strfrom-skeleton.c (STRFROM): Set member info.is_binary128 to one. * sysdeps/ieee754/float128/Makefile: Add strfromf128. * sysdeps/ieee754/float128/Versions: Likewise. * sysdeps/ieee754/float128/strfromf128.c: New file. --- stdlib/stdlib.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'stdlib/stdlib.h') diff --git a/stdlib/stdlib.h b/stdlib/stdlib.h index 428ca2e..0a693c2 100644 --- a/stdlib/stdlib.h +++ b/stdlib/stdlib.h @@ -51,6 +51,9 @@ __BEGIN_DECLS # endif #endif /* X/Open or XPG7 and not included. */ +/* _FloatN API tests for enablement. */ +#include + /* Returned by `div'. */ typedef struct { @@ -175,6 +178,12 @@ extern int strfroml (char *__dest, size_t __size, const char *__format, __THROW __nonnull ((3)); #endif +#if __HAVE_FLOAT128 && __GLIBC_USE (IEC_60559_TYPES_EXT) +extern int strfromf128 (char *__dest, size_t __size, const char * __format, + _Float128 __f) + __THROW __nonnull ((3)); +#endif + #ifdef __USE_GNU /* The concept of one static locale per category is not very well -- cgit v1.1
