Owen Anderson 3bbcbeaeff v2f16 is a floating point type. Add symbolic floating point type ranges to prevent this kind of issue in the future.

Sebastian Redl 2b80af4949 Don't route explicit construction via list-initialization through the functional cast code path. It sometimes does the wrong thing, produces horrible error messages, and is just unnecessary.

Dylan Noblesmith c6c7a5819d add LLVM_VERSION_MAJOR and _MINOR defines 
This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.

Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

Anna Zaks d56c8794d3 [analyzer] Malloc checker: rework realloc handling: 
1) Support the case when realloc fails to reduce False Positives. (We
essentially need to restore the state of the pointer being reallocated.)

2) Realloc behaves differently under special conditions (from pointer is
null, size is 0). When detecting these cases, we should consider
under-constrained states (size might or might not be 0). The
old version handled this in a very hacky way. The code did not
differentiate between definite and possible (no consideration for
under-constrained states). Further, after processing each special case,
the realloc processing function did not return but chained to the next
special case processing. So you could end up in an execution in which
you first see the states in which size is 0 and realloc ~ free(),
followed by the states corresponding to size is not 0 followed by the
evaluation of the regular realloc behavior.

Douglas Gregor e556163a66 Split the storage of lambda information between the LambdaExpr and the 
CXXRecordDecl in a way that actually makes some sense:
  - LambdaExpr contains all of the information for initializing the
  lambda object, including the capture initializers and associated
  array index variables.
  - CXXRecordDecl's LambdaDefinitionData contains the captures, which
  are needed to understand the captured variable references in the
  body of the lambda.

 2012-02-13 15:51:35 +00:00
Douglas Gregor c8a734938b Move the storage of lambda captures and capture initializers from 
LambdaExpr over to the CXXRecordDecl. This allows us to eliminate the
back-link from the closure type to the LambdaExpr, which will simplify
and lazify AST deserialization.
