From 9c9b62d8ddc9d61abad5106b819bb3ca9912d572 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 17 Jul 2013 11:44:55 +0200 Subject: score: Changes due to Newlib __DYNAMIC_REENT__ Delete _Thread_libc_reent and add __getreent() instead according to __DYNAMIC_REENT__ define. For SMP configurations __DYNAMIC_REENT__ must be defined. A Newlib including the following patch is required: 2013-07-09 Sebastian Huber * libc/include/sys/config.h (__DYNAMIC_REENT__): Define for RTEMS. --- cpukit/score/include/rtems/score/thread.h | 3 +++ cpukit/score/inline/rtems/score/thread.inl | 2 ++ cpukit/score/src/threaddispatch.c | 2 ++ 3 files changed, 7 insertions(+) (limited to 'cpukit/score') diff --git a/cpukit/score/include/rtems/score/thread.h b/cpukit/score/include/rtems/score/thread.h index 5e8bc950a7..9ce8ad1fd1 100644 --- a/cpukit/score/include/rtems/score/thread.h +++ b/cpukit/score/include/rtems/score/thread.h @@ -499,6 +499,7 @@ SCORE_EXTERN uint32_t _Thread_Ticks_per_timeslice; SCORE_EXTERN Thread_Control *_Thread_Allocated_fp; #endif +#if !defined(__DYNAMIC_REENT__) /** * The C library re-enter-rant global pointer.
