[analyzer] Implement "do not inline large functions many times"
performance heuristic

After inlining a function with more than 13 basic blocks 32 times, we
are not going to inline it anymore. The idea is that inlining large
functions leads to drastic performance implications. Since the function
has already been inlined, we know that we've analyzed it in many
contexts.

The following metrics are used:
 - Large function is a function with more than 13 basic blocks (we
should switch to another metric, like cyclomatic complexity)
 - We consider that we've inlined a function many times if it's been
inlined 32 times. This number is configurable with -analyzer-config
max-times-inline-large=xx

This heuristic addresses a performance regression introduced with
inlining on one benchmark. The analyzer on this benchmark became 60
times slower with inlining turned on. The heuristic allows us to analyze
it in 24% of the time. The performance improvements on the other
benchmarks I've tested with are much lower - under 10%, which is
expected.

This is a Band-Aid fix to a false positive, where we complain about not
initializing self to [super init], where self is not coming from the
init method, but is coming from the caller to init.

11 years agoMore hacking on mapDiagnosticRanges to make it handle more cases.
Eli Friedman [Thu, 13 Dec 2012 00:14:59 +0000 (00:14 +0000)]
More hacking on mapDiagnosticRanges to make it handle more cases.
This still isn't quite right, but it fixes a crash.

I factored out findCommonParent because we need it on the result of
getImmediateExpansionRange: for a function macro, the beginning
and end of an expansion range can come out of different
macros/macro arguments, which means the resulting range is a complete
mess to handle consistently.

I also made some changes to how findCommonParent works; it works somewhat
better in some cases, and somewhat worse in others, but I think overall
it's a better balance.  I'm coming to the conclusion that mapDiagnosticRanges
isn't using the right algorithm, though: chasing the caret is fundamentally
more complicated than any algorithm which only considers one FileID for the
caret can handle because each SourceLocation doesn't really have a single parent.
We need to follow the same path of choosing expansion locations and spelling
locations which the caret used to come up with the correct range
in the general case.
