From 78d401327f3bcbb06f5d6b388a967cae2ab42b43 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 27 Jun 2017 11:00:05 -0300 Subject: nptl: Add C11 threads tss_* functions This patch adds the tss_* definitions from C11 threads (ISO/IEC 9899:2011), more specifically tss_create, tss_delete, tss_get, tss_set, and required types. Mostly of the definitions are composed based on POSIX conterparts, including tss_t (pthread_key_t). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. [BZ #14092] * conform/data/threads.h-data (thread_local): New macro. (TSS_DTOR_ITERATIONS): Likewise. (tss_t): New type. (tss_dtor_t): Likewise. (tss_create): New function. (tss_get): Likewise. (tss_set): Likewise. (tss_delete): Likewise. * nptl/Makefile (libpthread-routines): Add tss_create, tss_delete, tss_get, and tss_set objects. * nptl/Versions (libpthread) [GLIBC_2.28]: Likewise. * nptl/tss_create.c: New file. * nptl/tss_delete.c: Likewise. * nptl/tss_get.c: Likewise. * nptl/tss_set.c: Likewise. * sysdeps/nptl/threads.h (thread_local): New define. (TSS_DTOR_ITERATIONS): Likewise. (tss_t): New typedef. (tss_dtor_t): Likewise. (tss_create): New prototype. (tss_get): Likewise. (tss_set): Likewise. (tss_delete): Likewise. --- conform/data/threads.h-data | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'conform/data') diff --git a/conform/data/threads.h-data b/conform/data/threads.h-data index d7c562eb19..406e497726 100644 --- a/conform/data/threads.h-data +++ b/conform/data/threads.h-data @@ -1,6 +1,8 @@ #if defined ISO11 macro ONCE_FLAG_INIT +macro thread_local +macro-int-constant TSS_DTOR_ITERATIONS constant thrd_success constant thrd_busy @@ -17,6 +19,8 @@ type thrd_start_t type mtx_t type once_flag type cnd_t +type tss_t +type tss_dtor_t function int thrd_create (thrd_t*, thrd_start_t, void*) function int thrd_equal (thrd_t, thrd_t) @@ -43,6 +47,11 @@ function int cnd_wait (cnd_t*, mtx_t*) function int cnd_timedwait (cnd_t*, mtx_t*, const struct timespec*) function void cnd_destroy (cnd_t*) +function int tss_create (tss_t*, tss_dtor_t) +function {void*} tss_get (tss_t) +function int tss_set (tss_t, void*) +function void tss_delete (tss_t) + #include "time.h-data" #endif -- cgit v1.2.3
