A large majority of the LIT tests of the clang static analyzer use RUN
lines with the placeholder `%clang_analyze_cc1` which expands to
`%clang_cc1 -analyze -setup-static-analyzer` where the only effect of
`-setup-static-analyzer` is that it ensures that the macro
`__clang_analyzer__` is defined. However, there were some tests that
used `%clang_cc1 -analyze` directly; this commit changes those to using
`%clang_analyze_cc1` for the sake of consistency.
Previously `%clang_analyze_cc1` did not work within the directory
`exploded-graph-rewriter` (because that directory has its own custom
`lit.local.cfg`) but this problem was eliminated by the recent commit
40cc4379cda6e0d6efe72c55d1968f9cf427a16a, so it was possible to resolve
and delete the FIXME comments asking for this change.
There are a few tests that use `%clang --analyze` or other command-line
flags (e.g. help flags), those are not affected by this change.
This cleanup was discussed in the discourse thread
https://discourse.llvm.org/t/taking-ownership-of-clang-test-analysis/84689/11
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).
* ExprEngine assumes that OpenMP statements should never appear in CFG.
However, current CFG doesn't know anything about OpenMP and passes
such statements as CFG nodes causing "UNREACHABLE executed!" crashes.
Since there is no OpenMP implementation in ExprEngine or CFG,
we stop the analysis on OpenMP statements to avoid crashes.
This fixes PR31835.
