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, SCANF_LDBL_USES_FLOAT128, which tells __vfscanf_internal to call __strtof128_internal, instead of __strtold_internal, and save the output into a _Float128 variable. Tested for powerpc64le. * sysdeps/ieee754/ldbl-128ibm-compat/Makefile (routines): Add ieee128-fscanf, ieee128-scanf, ieee128-sscanf, ieee128-vfscanf, ieee128-vscanf, and ieee128-vsscanf. (CFLAGS-vfscanf-internal.c): Add -mfloat128 to the compiler command used to build vfscanf-internal.c. This is needed to extend __vfscanf_internal with the support to redirect the call to __strtold_internal to __strtof128_internal. (tests-internal): Add test-scanf-ieee128 and test-scanf-ibm128. (CFLAGS-test-scanf-ieee128.c): New variable. (CFLAGS-test-scanf-ibm128.c): Likewise. ($(objpfx)test-scanf-ieee128): Link the loader after libgcc. [run-built-tests] (tests-special): Add $(objpfx)test-scanf-ieee128.out and $(objpfx)test-scanf-ibm128.out. ($(objpfx)test-scanf-ieee128.out): New build and run rule. ($(objpfx)test-scanf-ibm128.out): Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/Versions (libc): Add __fscanfieee128, __scanfieee128, __sscanfieee128, __vfscanfieee128, __vscanfieee128, and __vsscanfieee128. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fscanf.c: New file. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-scanf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-sscanf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vfscanf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vscanf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vsscanf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ibm128.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ieee128.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat-template.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat.sh: Likewise. --- sysdeps/ieee754/ldbl-128ibm-compat/Makefile | 35 +++++- sysdeps/ieee754/ldbl-128ibm-compat/Versions | 8 ++ .../ieee754/ldbl-128ibm-compat/ieee128-fscanf.c | 34 ++++++ sysdeps/ieee754/ldbl-128ibm-compat/ieee128-scanf.c | 34 ++++++ .../ieee754/ldbl-128ibm-compat/ieee128-sscanf.c | 38 +++++++ .../ieee754/ldbl-128ibm-compat/ieee128-vfscanf.c | 26 +++++ .../ieee754/ldbl-128ibm-compat/ieee128-vscanf.c | 26 +++++ .../ieee754/ldbl-128ibm-compat/ieee128-vsscanf.c | 29 +++++ .../ieee754/ldbl-128ibm-compat/test-scanf-ibm128.c | 1 + .../ldbl-128ibm-compat/test-scanf-ieee128.c | 1 + .../test-scanf-ldbl-compat-template.c | 117 +++++++++++++++++++++ .../ldbl-128ibm-compat/test-scanf-ldbl-compat.c | 10 ++ .../ldbl-128ibm-compat/test-scanf-ldbl-compat.sh | 63 +++++++++++ 13 files changed, 420 insertions(+), 2 deletions(-) create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fscanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-scanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-sscanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vfscanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vscanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vsscanf.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ibm128.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ieee128.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat-template.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-scanf-ldbl-compat.sh diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile index 88cb36576b..10fd6bbffc 100644 --- a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile +++ b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile @@ -45,12 +45,22 @@ routines += ieee128-vfwprintf_chk routines += ieee128-vswprintf_chk routines += ieee128-vwprintf_chk +routines += ieee128-fscanf +routines += ieee128-scanf +routines += ieee128-sscanf + +routines += ieee128-vfscanf +routines += ieee128-vscanf +routines += ieee128-vsscanf + # Printing long double values with IEEE binary128 format reuses part # of the internal float128 implementation (__printf_fp, __printf_fphex, -# and __float128 variables and union members).
