This patch fixes wrong annotation of profiles when call statement is de-duplicated. i.e., when we may have same stmt executing from more than one path (by jumping to same statment). Thus, the profile we get will be for multiple paths and would make the annotated profile wrong. As a fix, we dont annotate profile for GIMPLE_CALL stmt and extract BB counts from edge counts.
Regression tested on aarch64-linux-gnu with no new regression. Also successfully done autoprofiledbootstrap with the relevant patch. Is this OK for trunk? Thanks, Kugan
