[PATCH 10/14] ldbl-128ibm-compat: Add wide character scanning functions
- From: "Gabriel F. T. Gomes" <gabriel at inconstante dot eti dot br>
- To: <libc-alpha at sourceware dot org>
- Date: Wed, 20 Jun 2018 23:10:19 -0300
- Subject: [PATCH 10/14] ldbl-128ibm-compat: Add wide character scanning functions
- References: <20180621021023.17036-1-gabriel@inconstante.eti.br>
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).
Tested for powerpc64le.
* sysdeps/ieee754/ldbl-128ibm-compat/Makefile (routines): Add
ieee128-fwscanf, ieee128-swscanf, ieee128-wscanf,
ieee128-vfwscanf, ieee128-vswscanf, and ieee128-vwscanf
(CFLAGS-vfwscanf-internal.c): Add -mfloat128 to the compiler
command used to build vfwscanf-internal.c. This is needed to
extend __vfwscanf_internal with the support to redirect the call
to __wcstold_internal to __wcstof128_internal.
(tests-internal): Add test-wscanf-ieee128 and test-wscanf-ibm128.
(CFLAGS-test-wscanf-ieee128.c): New variable.
(CFLAGS-test-wscanf-ibm128.c): Likewise.
($(objpfx)test-wscanf-ieee128): Link the loader after libgcc.
[run-built-tests] (tests-special): Add
$(objpfx)test-wscanf-ieee128.out and
$(objpfx)test-wscanf-ibm128.out.
($(objpfx)test-wscanf-ieee128.out): New build and run rules.
($(objpfx)test-wscanf-ibm128.out): Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/Versions: Add
__fwscanfieee128, __swscanfieee128, __wscanfieee128,
__vfwscanfieee128, __vswscanfieee128, and __vwscanfieee128.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fwscanf.c: New file.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-swscanf.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vfwscanf.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vswscanf.c: Likewise.

* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-wscanf.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/test-wscanf-ibm128.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/test-wscanf-ieee128.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm-compat/test-wscanf-ldbl-compat.c:
Likewise.
