TLS: Add logic to get/set arbitrary TLS values
2016-03-11 02:31:22 +01:00
############################################################################
This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now. Squashed commit of the following: libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected). libs/: Fix paths in moved library directories. libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.

libs/libc/tls/tls_getinfo.c: Add tls_get_info() Move the logic to get TLS information from an inline function to a normal function. For the unaligned case, it is probably too large to be inlined. Also fixes some minor things from review of previous commits.

fix up_tls_info define for BUILD_KERNEL Summary: - In case of BUILD_KERNEL, NuttX uses USR mode sp and SVC mode sp. - The kernel runs on SVC mode sp. - While the kernel is running, up_getsp() cannot get the TLS address. - The kernel requires tls_get_info() function. - For the user land, up_getsp() can be used. - tls_getinfo.c is always compiled and tls_get_info() function is filtered by macros in the tls_getinfo.c. Impact: BUILD_KERNEL Testing: test program on custom Cortex-A9 board (BUILD_KERNEL) ostest on sabre-6quad:smp (QEMU, BUILD_FLAT) Signed-off-by: Oki Minabe <minabe.oki@gmail.com>

Remove CONFIG_TLS A first step in implementing the user-space error is force TLS to be enabled at all times. It is no longer optional

Completes the Implementation of the TLS-based errno - Remove per-thread errno from the TCB structure (pterrno) - Remove get_errno() and set_errno() as functions. The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode). - Add errno value to the tls_info_s structure definitions - Move sched/errno to libs/libc/errno. Replace old TCB access to the errno with TLS access to the errno.
