greenhills compiler turn off optimization for file or part of

问题

I found several code snippets for disabling GCC optimization for dedicated code parts.

with pragma GCC optimize(0)

But I could not found something like that for Greenhils compiler.

Is there no such option?

回答1:

From the manual:

#pragma ghs Ostring
Turns on optimizations. The optional string may contain any or all of the following letters:
L — Loop optimizations
M — Memory optimizations
S — Small (but Slow) optimizations

#pragma ghs ZO
Disables all optimizations, starting from the next function.
