[analyzer] Implement basic path diagnostic pruning based on "interesting" symbols and regions. · 1e809b4c

Ted Kremenek authored Mar 09, 2012

Essentially, a bug centers around a story for various symbols and regions. We should only include
the path diagnostic events that relate to those symbols and regions.

The pruning is done by associating a set of interesting symbols and regions with a BugReporter, which
can be modified at BugReport creation or by BugReporterVisitors.

This patch reduces the diagnostics emitted in several of our test cases. I've vetted these as
having desired behavior. The only regression is a missing null check diagnostic for the return
value of realloc() in test/Analysis/malloc-plist.c. This will require some investigation to fix,
and I have added a FIXME to the test case.

Change the test driver so that, by default, it takes into consideration of both 'x86_64' and 'i386' architectures
when building the inferior programs.

[analyzer] Use call graph to determine order in which functions are · eee91107

analyzed.

The CallGraph is used when inlining is on, which is the current default.

This alone does not bring any performance improvement. It's a
stepping stone for the upcoming optimization in which we do not
re-analyze a function that has already been analyzed while inlined in
other functions. Using the call graph makes it easier to play with
the order of functions to minimize redundant analyzes.

Fix a couple of issues with literal-operator-id parsing, and provide recovery · 7d182a79

Richard Smith authored Mar 08, 2012

for a few kinds of error. Specifically:

Since we're after translation phase 6, the "" token might be formed by multiple
source-level string literals. Checking the token width is not a correct way of
detecting empty string literals, due to escaped newlines. Diagnose and recover
from a missing space between "" and suffix, and from string literals other than
"", which are followed by a suffix.

- Remove FinalRead · 3cbe5cff
  Tobias Grosser authored Mar 08, 2012
```
The FinalRead statement represented a virtual read that is executed after the
SCoP. It was used when we verified the correctness of a schedule by checking if
it yields the same FLOW dependences as the original code. This is only works, if
we have a final read that reads all memory at the end of the SCoP.
We now switched to just checking if a schedule does not introduce negative
dependences and also consider WAW WAR dependences. This restricts the schedules
a little bit more, but we do not have any optimizer that would calculate a more
complex schedule. Hence, for now final reads are obsolete.
