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. --- cpukit/score/cpu/unix/rtems/score/cpu.h | 1 + 1 file changed, 1 insertion(+) (limited to 'cpukit/score/cpu/unix/rtems/score/cpu.h') diff --git a/cpukit/score/cpu/unix/rtems/score/cpu.h b/cpukit/score/cpu/unix/rtems/score/cpu.h index d7019c3eec..7e0cbf7777 100644 --- a/cpukit/score/cpu/unix/rtems/score/cpu.h +++ b/cpukit/score/cpu/unix/rtems/score/cpu.h @@ -158,6 +158,7 @@ extern "C" { */ #define CPU_HARDWARE_FP TRUE +#define CPU_SOFTWARE_FP FALSE /* * Are all tasks RTEMS_FLOATING_POINT tasks implicitly? -- cgit v1.2.3
