From 29ff9055c80efe77a7130767a9fcb3ab8c67e8ce Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 24 Sep 2016 02:55:31 +0200 Subject: use a single libc and deduplicate threading code Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance --- .../nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c | 125 --------------------- 1 file changed, 125 deletions(-) delete mode 100644 libpthread/nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c (limited to 'libpthread/nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c') diff --git a/libpthread/nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c b/libpthread/nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c deleted file mode 100644 index 71fef93d3..000000000 --- a/libpthread/nptl/sysdeps/unix/sysv/linux/sh/pt-initfini.c +++ /dev/null @@ -1,125 +0,0 @@ -/* Special .init and .fini section support for SH.
