From b7b88cea4151d85eafd7ababc2e4b7ae1daeedf5 Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Thu, 28 Jun 2018 22:38:55 -0300 Subject: 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. --- sysdeps/ieee754/ldbl-128ibm-compat/Makefile | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/Makefile (limited to 'sysdeps/ieee754/ldbl-128ibm-compat/Makefile') diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile new file mode 100644 index 0000000000..412beb5b5c --- /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-printfsz-islongdouble.sh $(objpfx)test-printf-size-ieee128 + $(SHELL) $^ '$(test-program-prefix)' $@; \ + $(evaluate-test) + +$(objpfx)test-printf-size-ibm128.out: \ + tst-printfsz-islongdouble.sh $(objpfx)test-printf-size-ibm128 + $(SHELL) $^ '$(test-program-prefix)' $@; \ + $(evaluate-test) +endif -- cgit 1.4.1
