The optimization can be disabled by deselecting the Enable optimization in Project->Options->Compile->General. Also are you optimizing for size or for performance. when you are optimizing for the size the com-piler disables loop unrolling, delay slot filling, and jump avoidance. I think the problem lies there.

For C files, you can right-clicking on the C file in the Project Window, select File Options-> Build With File Specific Settings (button) -> Compile (tab) and disable optimization (button). You can also add Additional Options to control the optimization level (-O0 to disable optizations) Regards Don Waldron > -----Original Message----- > From: [SMTP:] > Sent: Wednesday, March 06, 2002 6:13 PM > To: > Subject: [adsp] VisualDSP 2.0 optimizer > > 'm having trouble with the optimizer in the SHARC VisualDSP 2.0 > removing "un-necessary" code, which renders the code non- > functional.

'm having trouble with the optimizer in the SHARC VisualDSP 2.0 removing "un-necessary" code, which renders the code non- functional. Is there *any* way to turn off the optimizer in the source module with a pragma? Thanks --Rob Alexander
