[cfe-dev] how to run no optimization except inlining at O3 level when generating IR

[林政宗 via cfe-dev]

Hi,
If I put the pragma outside the function, optnone will override the always_inline attribute.
And if always_inline doesn't function, the result of this funciton will be wrong for some reason.
I hope that clang can inline this function but does no optimizaton on function body. 
Is there a solution to achieve this?


Thanks!

Put the pragma directive outside the function.


The optnone attribute is for functions.
