Ted Kremenek 6bd78709f2 retain/release checker: Hoist code for bug reports above transfer function logic

Ted Kremenek bcf597d2e5 Add test case for transfer function logic for OSCompareAndSwap32Barrier. 
llvm-svn: 70383
 2009-04-29 16:03:59 +00:00
Ted Kremenek 3941d22a98 Add corner case logic to BasicStoreManager and GRSimpleVals::EvalBinOp to enable 
reasoning about OSCompareAndSwap32Barrier/OSCompareAndSwap64Barrier. Essentially
the address of reference to a region (pointer-to-pointer) can be casted to
(int32_t*), and we need to handle the logic to convert the involved locations
back and forth from nonloc::LocAsInteger, nonloc::ConcreteInt, to Loc and
loc::ConcreteInt respectively. This adds some potentially suspect logic to
BasicStoreManager that allows the analyzer to reason about abuses of the C type
system. This should probably be refined, be ported over to RegionStoreManager,
and extended with "path-sensitive type checking" to flag bugs in clearly
incoherent code.

Chris Lattner 0f94c5a741 Fix PR4092 by improving error recovery in two ways: 
1. In a struct field redefinition, don't mark the struct erroneous.  The
   field is erroneous, but the struct is otherwise well formed.
2. Don't emit diagnostics about functions that are known to be broken already.

Either fix is sufficient to silence the second diagnostic in the example,
but the combination is better :)

This enables one specific class of non-literal format warnings.

Chris Lattner fd4a4d1f8a Wire up -Wformat=2 and -Wformat-extra-args 
llvm-svn: 70364
 2009-04-29 04:31:58 +00:00
Chris Lattner 83a3235a3e -Wformat should depend on format-extra-args so that -Wformat implies 
the extra argument warnings, and -Wformat -Wno-format-extra-args
turns on -Wformat but not the extra-args warnings.

llvm-svn: 70363
 2009-04-29 04:16:52 +00:00
Chris Lattner 941153afcd tweak warning options to be more like gcc: 
1. All all variants of -Wformat*, make them imply -Wformat.  GCC warns 
   if you use -Wformatfoo without -Wformat.  We just make one imply the 
   other.
2. Make -Wformat-nonliteral default to off, like gcc.  It is an incredible
   nuisance.
3. Accept but currently ignore -Wformat-extra-args.

Chris Lattner e3fa5aa91c minor code cleanup 
llvm-svn: 70361
 2009-04-29 04:12:34 +00:00
Chris Lattner 7d10386113 Disable the load-shrinking optimization from looking at 
anything larger than 64-bits, avoiding a crash.  This should
really be fixed to use APInts, though type legalization happens
to help us out and we get good code on the attached testcase at
least.

Bill Wendling 9f795134f3 The second part of the change from -fast to -O#. This changes the JIT to accept 
an optimization level instead of a simple boolean telling it to generate code
"fast" or the other type of "fast".

llvm-svn: 70347
 2009-04-29 00:32:19 +00:00
Bill Wendling 084669a1c9 Second attempt: 
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.
