The source file that exhibits the failure to inline always_inline functions.
I have a similar problem compiling Thunderbird mail client with GCC-12.
A couple of always_inline functions cannot be inlined and errors are diagnosed.
I am a bit perplexed that gcc-10 and gcc-11 did not seem to have the problem.
Also, I am wondering if I am seeing the same issue discussed here or not
because I think the functions are declared in the proper topological order
(that is, the function that is called is declared in a manner that the callee
is defined before the caller.)
Yes, there is an indirect function call, that may be the reason of the failure.
I am attaching a preprocessed source file and the script to compile it to cause
the failure.
The presence of -Og is essential. If we remove -Og, the compilation succeeds.
