This is achieved by setting the 'is_binary128' member of the 'printf_info' structure to 1. 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. Tested for powerpc64le. * sysdeps/ieee754/ldbl-128ibm-compat/Makefile: [subdir == stdio-common] (routines): Add ieee128-printf_size. [subdir == stdio-common] (tests-internal): Add test-printf-size-ieee128, and test-printf-size-ibm128. [subdir == stdio-common] (CFLAGS-test-printf-size-ieee128.c) (CFLAGS-test-printf-size-ibm128.c): New variables. [subdir == stdio-common] (tests-special): Add $(objpfx)test-printf-size-ieee128.out and $(objpfx)test-printf-size-ibm128.out. [subdir == stdio-common] ($(objpfx)test-printf-size-ieee128.out) ($(objpfx)test-printf-size-ibm128.out): New build and run rules. * sysdeps/ieee754/ldbl-128ibm-compat/Versions (libc): Add __printf_sizeieee128. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf_size.c: New file. * sysdeps/ieee754/ldbl-128ibm-compat/test-printf-size-ibm128.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-printf-size-ieee128.c: Likewise. --- sysdeps/ieee754/ldbl-128ibm-compat/Makefile | 22 +++++++++++++++ sysdeps/ieee754/ldbl-128ibm-compat/Versions | 2 ++ .../ldbl-128ibm-compat/ieee128-printf_size.c | 32 ++++++++++++++++++++++ .../ldbl-128ibm-compat/test-printf-size-ibm128.c | 1 + .../ldbl-128ibm-compat/test-printf-size-ieee128.c | 1 + 5 files changed, 58 insertions(+) create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/Makefile create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf_size.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-printf-size-ibm128.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/test-printf-size-ieee128.c diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile new file mode 100644 index 0000000000..bead846ea4 --- /dev/null +++ b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile @@ -0,0 +1,22 @@ +ifeq ($(subdir),stdio-common) +routines += ieee128-printf_size + +tests-internal += test-printf-size-ieee128 test-printf-size-ibm128 +CFLAGS-test-printf-size-ieee128.c += -mfloat128 -mabi=ieeelongdouble -Wno-psabi +CFLAGS-test-printf-size-ibm128.c += -mabi=ibmlongdouble -Wno-psabi + +ifeq ($(run-built-tests),yes) +tests-special += $(objpfx)test-printf-size-ieee128.out +tests-special += $(objpfx)test-printf-size-ibm128.out +endif + +$(objpfx)test-printf-size-ieee128.out: \ + tst-isbinary128.sh $(objpfx)test-printf-size-ieee128 + $(SHELL) $^ '$(test-program-prefix)' $@; \ + $(evaluate-test) + +$(objpfx)test-printf-size-ibm128.out: \ + tst-isbinary128.sh $(objpfx)test-printf-size-ibm128 + $(SHELL) $^ '$(test-program-prefix)' $@; \ + $(evaluate-test) +endif diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/Versions b/sysdeps/ieee754/ldbl-128ibm-compat/Versions index f4047f06a6..4aa34dbe59 100644 --- a/sysdeps/ieee754/ldbl-128ibm-compat/Versions +++ b/sysdeps/ieee754/ldbl-128ibm-compat/Versions @@ -118,4 +118,6 @@ libc { __strtoieee128_l; __wcstoieee128; __wcstoieee128_l; + + __printf_sizeieee128; } diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf_size.c b/sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf_size.c new file mode 100644 index 0000000000..d0ef0593ac --- /dev/null +++ b/sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf_size.c @@ -0,0 +1,32 @@ +/* Wrapper for printf_size.
