ARC: multiple definition of `__vfork'

Hello, uClibc-ng 1.0.3 causes a build failure when linking alsa-lib statically, due to __vfork() being defined in both libc.a and libpthread.a: aserver.o: In function `pcm_shm_cmd': aserver.c:(.text+0x135a): warning: /home/peko/autobuild/instance-0/output/host/usr/arc-buildroot-linux-uclibc/sysroot/usr/lib/libc.a(vfork.os): In function `__vfork': (.text+0x0): multiple definition of `__vfork' /home/peko/autobuild/instance-0/output/host/usr/arc-buildroot-linux-uclibc/sysroot/usr/lib/libpthread.a(pt-vfork.os):(.text+0x0): first defined here collect2: error: ld returned 1 exit status See more build output at: http://autobuild.buildroot.org/results/c37/c37f8b8a27115208aa7db885d9dfdf3a… Best regards, Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com

[PATCH] test/tls: xtensa: fix TLS_LD definition
by Max Filippov 07 Jul '15

07 Jul '15

TLS_LD should use linker-provided symbol _TLS_MODULE_BASE_ instead of symbol it resolves to get thread pointer, otherwise linker relaxation doesn't work correctly, adding extra offset to thread-local variable address. This fixes most of tls/tst-tls* tests.
