Hi Muni,
Probably gcc is automatic inlining your function even in the
absence of 'inline' keyword...
Take a look here:
http://www.cocoabuilder.com/archive/xcode/269025-how-to-disable-gcc-automatic-inlining.html
And here:
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
There are a few inline related flags, including this:
-finline-functions-called-once
Consider all static functions called once for inlining into their
caller even if they are not marked inline. If a call to a given
function is integrated, then the function is not output as assembler
code in its own right.
Enabled at levels -O1, -O2, -O3 and -Os.
Best regards,
