From 45dcd79f6eb37ad4e9e6967f1d459ffc3629eb1f Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 17 Jun 2015 20:15:22 +0000 Subject: Fix swscanf vswscanf namespace (bug 18542). swscanf (added in C90 Amendment 1, present in UNIX98) calls vswscanf (added in C99, not in C90 Amendment 1 or UNIX98). This patch fixes this by using __vswscanf instead and making vswscanf into a weak alias. (I intend to add conform/ test support for C90 Amendment 1 - and various other standard versions supported by glibc but not yet by conform/ tests - at some point, once the results for currently tested standards are cleaner.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18542] * libio/iovswscanf.c (__vswscanf): Use libc_hidden_def. (vswscanf): Use ldbl_weak_alias instead of ldbl_strong_alias * include/wchar.h (__vswscanf): Declare. Use libc_hidden_proto. * libio/swscanf.c (__swscanf): Call __vswscanf instead of vswscanf. * conform/Makefile (test-xfail-UNIX98/wchar.h/linknamespace): Remove variable. --- conform/Makefile | 1 - 1 file changed, 1 deletion(-) (limited to 'conform') diff --git a/conform/Makefile b/conform/Makefile index 32d2985..0b06103 100644 --- a/conform/Makefile +++ b/conform/Makefile @@ -348,4 +348,3 @@ test-xfail-XPG3/unistd.h/linknamespace = yes test-xfail-XPG4/unistd.h/linknamespace = yes test-xfail-POSIX/mqueue.h/linknamespace = yes test-xfail-UNIX98/mqueue.h/linknamespace = yes -test-xfail-UNIX98/wchar.h/linknamespace = yes -- cgit v1.1
