From: Gabriel F.T.Gomes <gftg@sourceware.org> To: glibc-cvs@sourceware.org Subject: [glibc/gabriel/powerpc-ieee128-printscan] ldbl-128ibm-compat: Add regular character printing functions Date: Fri, 09 Aug 2019 18:35:00 -0000 [thread overview] Message-ID: <20190809183522.84227.qmail@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=99ec0318a3e820a0fcf4fcea4d25669f11de835d commit 99ec0318a3e820a0fcf4fcea4d25669f11de835d Author: Gabriel F. T. Gomes <gabrielftg@linux.ibm.com> Date: Thu Aug 8 10:42:35 2019 -0300 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. * elf/tst-addr1.c (do_test): Accept redirections of printf to __printfieee128. * sysdeps/ieee754/ldbl-128ibm-compat/Makefile [subdir == stdio-common] (routines): Move the addition of printf_size to ldbl-extra-routines. [subdir == stdio-common] (ldbl-extra-routines): New variable. [subdir == stdio-common] (ldbl-ibm128-files): New variable. [subdir == stdio-common] (obj-suf-foreach): New routine. [subdir == stdio-common] (CFLAGS-vfprintf-internal.c): New variable. Add -mfloat128 to the compilation of vfprintf-internal.c, so that it gets support for the use of __printf_fp and __printf_fphex with __float128 parameter. [subdir == stdio-common] (tests-internal): Add test-printf-ieee128 and test-printf-ibm128. [subdir == stdio-common] (CFLAGS-test-printf-ieee128.c): New variable to add the relevant -mabi flags to the compilation. [subdir == stdio-common] (CFLAGS-test-printf-ibm128.c): Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/Versions: (libc): Add __asprintfieee128, __dprintfieee128, __fprintfieee128, __printfieee128, __snprintfieee128, __sprintfieee128, __vasprintfieee128, __vdprintfieee128, __vfprintfieee128, __vprintfieee128, __vsnprintfieee128, and __vsprintfieee128. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-asprintf.c: New file. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-dprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-fprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-printf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-snprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-sprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vasprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vdprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vfprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vsnprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/ieee128-vsprintf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-printf-ibm128.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-printf-ieee128.c: Likewise. * sysdeps/ieee754/ldbl-128ibm-compat/test-printf-ldbl-compat.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/le/ldbl-128ibm-compat-abi.h: Likewise.
