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. --- stdio-common/printf.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'stdio-common/printf.h') diff --git a/stdio-common/printf.h b/stdio-common/printf.h index 5d82e8d..6b207d2 100644 --- a/stdio-common/printf.h +++ b/stdio-common/printf.h @@ -47,7 +47,9 @@ struct printf_info unsigned int is_char:1; /* hh flag. */ unsigned int wide:1; /* Nonzero for wide character streams. */ unsigned int i18n:1; /* I flag. */ - unsigned int __pad:4; /* Unused so far. */ + unsigned int is_binary128:1; /* Floating-point argument is ABI-compatible + with IEC 60559 binary128. */ + unsigned int __pad:3; /* Unused so far. */ unsigned short int user; /* Bits for user-installed modifiers. */ wchar_t pad; /* Padding character. */ }; -- cgit v1.1
