From 17508d02bba1d47f4cf884b190566e72f69adb4e Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Wed, 26 Jul 2000 19:26:28 +0000 Subject: Port of RTEMS to the Texas Instruments C3x/C4x DSP families including a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4. --- c/src/exec/score/src/threadinitialize.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'c/src/exec/score/src/threadinitialize.c') diff --git a/c/src/exec/score/src/threadinitialize.c b/c/src/exec/score/src/threadinitialize.c index 0d5154c400..fe4e9fa2b5 100644 --- a/c/src/exec/score/src/threadinitialize.c +++ b/c/src/exec/score/src/threadinitialize.c @@ -95,6 +95,7 @@ boolean _Thread_Initialize( * Allocate the floating point area for this thread */ +#if ( CPU_HARDWARE_FP == TRUE ) || ( CPU_SOFTWARE_FP == TRUE ) if ( is_fp ) { fp_area = _Workspace_Allocate( CONTEXT_FP_SIZE ); @@ -109,6 +110,7 @@ boolean _Thread_Initialize( the_thread->fp_context = fp_area; the_thread->Start.fp_context = fp_area; +#endif /* * Allocate the extensions area for this thread -- cgit v1.2.3
