ldbl-128ibm-compat: Add wide character scanning functions Similarly to what was done for regular character scanning functions, this patch uses the new mode mask, SCANF_LDBL_USES_FLOAT128, in the 'mode' argument of the wide characters scanning function, __vfwscanf_internal (which is also extended to support scanning floating-point values with IEEE binary128, by redirecting calls to __wcstold_internal to __wcstof128_internal).

ldbl-128ibm-compat: fixup subdir location of several funcs We want to ensure that if a second file is built to support ieee128 long double, we built its companion implementation with ibm128 long double. The shared object versions of these files build correctly because the aliasing is sufficiently complex to prevent the redirects from applying when defining them. However, this does not prevent the static object variants from becoming quietly broken due to redirects. This is intentionally avoided by marking such objects to be built with -mabi=ibmlongdouble. Shuffle the misplaced routines to build against the subdir which defines the needed symbols.

ldbl-128ibm-compat: Add ISO C99 versions of scanf functions In the format string for *scanf functions, the '%as', '%aS', and '%a[]' modifiers behave differently depending on ISO C99 compatibility.

Otherwise, the ISO C99 compliant version of these functions is used, and the modifiers consume a floating-point argument.

ldbl-128ibm-compat: Add printf_size Since the addition of the _Float128 API, strfromf128 and printf_size use __printf_fp to print _Float128 values. This is achieved by setting the 'is_binary128' member of the 'printf_info' structure to one. Now that the format of long double on powerpc64le is getting a third option, this mechanism is reused for long double values that have binary128 format (i.e.: when -mabi=ieeelongdouble). This patch adds __printf_sizeieee128 as an exported symbol, but doesn't provide redirections from printf_size, yet. All redirections will be installed in a future commit, once all other functions that print or read long double values with binary128 format are ready. In __printf_fp, when 'is_binary128' is one, the floating-point argument is treated as if it was of _Float128 type, regardless of the value of 'is_long_double', thus __printf_sizeieee128 sets 'is_binary128' to the same value of 'is_long_double'. Otherwise, double values would not be printed correctly. Tested for powerpc64le.

ldbl-128ibm-compat: Add regular character printing functions The 'mode' argument to __vfprintf_internal allows the selection of the long double format for all long double arguments requested by the format string. Currently, there are two possibilities: long double with the same format as double or long double as something else. The 'something else' format varies between architectures, and on powerpc64le, it means IBM Extended Precision format. In preparation for the third option of long double format on powerpc64le, this patch uses the new mode mask, PRINTF_LDBL_USES_FLOAT128, which tells __vfprintf_internal to save the floating-point values into variables of type __float128 and adjusts the parameters to __printf_fp and __printf_fphex as if it was a call from strfromf128. Many files from the stdio-common, wcsmbs, argp, misc, and libio directories will have IEEE binary128 counterparts. Setting the correct compiler options to these files (original and counterparts) would produce a large amount of repetitive Makefile rules. To avoid this repetition, this patch adds a Makefile routine that iterates over the files adding or removing the appropriate flags. Tested for powerpc64le.

ldbl-128ibm-compat: Fix selection of GNU and ISO C99 scanf Since commit commit 03992356e6fedc5a5e9d32df96c1a2c79ea28a8f Author: Zack Weinberg <zackw@panix.com> Date: Sat Feb 10 11:58:35 2018 -0500 Use C99-compliant scanf under _GNU_SOURCE with modern compilers. the selection of the GNU versions of scanf functions requires both _GNU_SOURCE and -std=c89. This patch changes the tests in ldbl-128ibm-compat so that they actually test the GNU versions (without this change, the redirection to the ISO C99 version always happens, so GNU versions of the new implementation (e.g. __scanfieee128) were left untested).

ldbl-128ibm-compat: Add printf_size Since the addition of the _Float128 API, strfromf128 and printf_size use __printf_fp to print _Float128 values. This is achieved by setting the 'is_binary128' member of the 'printf_info' structure to one. Now that the format of long double on powerpc64le is getting a third option, this mechanism is reused for long double values that have binary128 format (i.e.: when -mabi=ieeelongdouble). This patch adds __printf_sizeieee128 as an exported symbol, but doesn't provide redirections from printf_size, yet. All redirections will be installed in a future commit, once all other functions that print or read long double values with binary128 format are ready. In __printf_fp, when 'is_binary128' is one, the floating-point argument is treated as if it was of _Float128 type, regardless of the value of 'is_long_double', thus __printf_sizeieee128 sets 'is_binary128' to the same value of 'is_long_double'. Otherwise, double values would not be printed correctly. Tested for powerpc64le.

The 'something else' format varies between architectures, and on powerpc64le, it means IBM Extended Precision format. In preparation for the third option of long double format on powerpc64le, this patch uses the new mode mask, PRINTF_LDBL_USES_FLOAT128, which tells __vfprintf_internal to save the floating-point values into variables of type __float128 and adjusts the parameters to __printf_fp and __printf_fphex as if it was a call from strfromf128. Many files from the stdio-common, wcsmbs, argp, misc, and libio directories will have IEEE binary128 counterparts. Setting the correct compiler options to these files (original and counterparts) would produce a large amount of repetitive Makefile rules. To avoid this repetition, this patch adds a Makefile routine that iterates over the files adding or removing the appropriate flags. Tested for powerpc64le.

The shared object versions of these files build correctly because the aliasing is sufficiently complex to prevent the redirects from applying when defining them. However, this does not prevent the static object variants from becoming quietly broken due to redirects. This is intentionally avoided by marking such objects to be built with -mabi=ibmlongdouble.

Unlike all other long double to/from string conversion functions, these do not rely on internal functions that can take floating-point numbers with different formats and act on them accordingly, instead, the related files are rebuilt with the -mabi=ieeelongdouble compiler flag set. Having -mabi=ieeelongdouble passed to the compiler causes the object files to be marked with a .gnu_attribute that is incompatible with the .gnu_attribute in files built with -mabi=ibmlongdouble (the default). The difference causes error messages similar to the following: ld: libc_pic.a(s_isinfl.os) uses IBM long double, libc_pic.a(ieee128-qefgcvt_r.os) uses IEEE long double. collect2: error: ld returned 1 exit status make[2]: *** [../Makerules:649: libc_pic.os] Error 1 Although this warning is useful in other situations, the library actually needs to have functions with different long double formats, so .gnu_attribute generation is explicitly disabled for these files with the use of -mno-gnu-attribute.

ldbl-128ibm-compat: Add regular character printing functions The 'mode' argument to __vfprintf_internal allows the selection of the long double format for all long double arguments requested by the format string. Currently, there are two possibilities: long double with the same format as double or long double as something else. The 'something else' format varies between architectures, and on powerpc64le, it means IBM Extended Precision format. In preparation for the third option of long double format on powerpc64le, this patch uses the new mode mask, PRINTF_LDBL_USES_FLOAT128, which tells __vfprintf_internal to save the floating-point values into variables of type __float128 and adjusts the parameters to __printf_fp and __printf_fphex as if it was a call from strfromf128. Many files from the stdio-common, wcsmbs, argp, misc, and libio directories will have IEEE binary128 counterparts. Setting the correct compiler options to these files (original and counterparts) would produce a large amount of repetitive Makefile rules. To avoid this repetition, this patch adds a Makefile routine that iterates over the files adding or removing the appropriate flags. Tested for powerpc64le.
