Compiling the following test case with FDO, virtual call base->Foo(id) is
promoted/specialized in valueProf transformation. However the resulting direct
call is not inlined due to type mismatch.
The problem is that the 2nd ARG_TYPE associated with the indirect call is a

The earlier comments should probably first be investigated by looking
in config.log. (Except the original comment which sounds like a missing
feature in depcomp -- that should go upstream to Automake.)

work-around of comment #5?

really avoid false positives is to look at the context of t

Maybe the C version will be usable after everyone is using 4.4+, earlier

Shifting by more than the bitsize of the value invokes undefined behavior
(GCC implements shift count truncation for targets that would do this in
hardware which is why you see 5 as result).
