|Subject:||[avr-gcc-list] FW: optimalisation level setting from within C-source code....|
|Date:||Tue, 16 Oct 2007 13:46:41 +0200|
first of all – I am first time writing to avr-gcc list members, and – I am only true hobbist of AVR programming..
So what I would need: within one C-source code, I have used some functions written for 1-wire-bus communication.
Some functions are timing-critical, and it was written WITHOUT any optimalisation and works OK.
When I tried to use -O default optimalisation (which is still usable for debugging with AVRStudio + JTAG), these functions stop to operate.
And my question:
Is it possible to set the optimalisation level for some functions (or part of source-code) to different level than optimalisation used for this project as default?
Eg. to use as default for project -O level, but for some partial code to use -O0 level..
How to write it into source-code – as some #pragma statement?
Thank you for your reply....
