2016-11-29cpukit: Add libdebugger, a remote debugger agent for GDB.Chris Johns1-0/+12
2016-11-23posix: Add self-contained pthread spinlockSebastian Huber1-0/+1
Turn pthread_spinlock_t into a self-contained object. On uni-processor configurations, interrupts are disabled in the lock/trylock operations and the previous interrupt status is restored in the corresponding unlock operations. On SMP configurations, a ticket lock is a acquired and released in addition. The self-contained pthread_spinlock_t object is defined by Newlib in <sys/_pthreadtypes.h>. typedef struct { struct _Ticket_lock_Control _lock; __uint32_t _interrupt_state; } pthread_spinlock_t; This implementation is simple and efficient. However, this test case of the Linux Test Project would fail due to call of printf() and sleep() during spin lock ownership: https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_spin_lock/1-2.c There is only limited support for profiling on SMP configurations. Delete CORE spinlock implementation. Update #2674.
2016-08-11build-system: Always enable C++ if the compiler is present.Chris Johns1-2/+4
We always build a C++ compiler and building with C++ does not effect RTEMS or the runtime. This patch always enabled the support. There is no need to manually enable it any more. You can disable C++ with '--disable-cxx'. If an architecture does not have a C++ compiler support is automatically disabled.
2016-05-02score: __RTEMS_DO_NOT_INLINE_CORE_MUTEX_SEIZE__Sebastian Huber1-6/+0
Delete __RTEMS_DO_NOT_INLINE_CORE_MUTEX_SEIZE__ as a preparation to restructure the CORE mutex variants and reduce the branch complexity.

2015-06-15Remove use ticks for statistics configure option.Joel Sherrill1-5/+0
This was obsolete and broken based upon recent time keeping changes. Thie build option was previously enabled by adding USE_TICKS_FOR_STATISTICS=1 to the configure command line. This propagated into the code as preprocessor conditionals using the __RTEMS_USE_TICKS_FOR_STATISTICS__ conditional.

2015-03-06Temporarily disable libdl for h8300Joel Sherrill1-1/+4
The h8300 gets a linking error for the dl0* tests. This temporarily disables libdl until that can be investigated. updates 2284.
2015-03-06Temporarily disable libdl for lm32Joel Sherrill1-1/+4
There is a GCC ICE when building libdl. This temporarily disables building libdl until that is resolved. updates 2283.
2015-03-06Temporarily disable libdl for v850Joel Sherrill1-1/+4
There is an issue linking dl0* which has not been resolved. This issue is being tracked but is not considered a release blocker. This patch is a workaround which disables libdl for the v850 until the ticket is resolved. updates 2260.

This work is based on the old or32 port (that has been removed back in 2005) authored by Chris Ziomkowski. The patch includes the basic functions every port should implement like: context switch, exception handling, OpenRISC ABI and machine definitions and configurations.

2013-12-02posix: Use cleanup contexts on the stackSebastian Huber1-0/+1
Provide support for latest Newlib <pthread.h> change. The cleanup contexts are stored on the thread stack. This is conformant with the POSIX requirements for the pthread_cleanup_push() and pthread_cleanup_pop() statement pair. Passing an invalid pointer as the routine to pthread_cleanup_push() is now a usage error and the behaviour is undefined.

2012-11-22score: PR1607: Add and use CPU_SIZEOF_POINTERSebastian Huber1-9/+0
Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code. The size of a pointer is part of the application binary interface (ABI) and thus independent of the actual programming language. The compiler will provide defines to determine the current ABI. We use these defines to select the appropriate CPU_SIZEOF_POINTER value. Static assertions in the new file "cpukit/score/src/percpuasm.c" will ensure that the value of CPU_SIZEOF_POINTER is consistent with the current compiler settings. Also the offset values used by assembler code are verfied.
