• score/cpu/sparc/cpu.c, score/cpu/sparc/rtems/score/cpu.h, score/include/rtems/score/context.h, score/src/threadhandler.c: Fix stack so gdb backtrace does not print corrupted frame message after _Thread_Handler. Daniel Hellstrom <daniel@…> provided the SPARC implementation and I made it more general.
