Dylan Noblesmith 92c07c27be refactor flags for TokenKinds.def 
Make KEYALL a combination of all other flags instead
of its own separate flag. Also rewrite the enum
definitions in hex instead of decimal.

Dylan Noblesmith 70e73a3d60 refactor -ccc-gcc-name code 
Put the logic for deciding the default name for gcc/g++
in the only place that actually cares about it.

This also pushes an ifdef out of the generic driver code
to a little further down, when the target is actually known.
Hopefully it can be changed into just a runtime check
in the future.

Eli Friedman 9cca0715aa Add back a couple checks removed by r129128; the fact that an intitializer 
is an array of structures doesn't imply it's a ConstantArray of
ConstantStruct.

Chandler Carruth 66a7b04767 Clean up the bool conversion warning. Group it with other conversion 
warnings, and make its text appropriate for constant bool expressions
other than 'false'. This should finish off PR9612.

llvm-svn: 129205
 2011-04-09 07:48:17 +00:00
Chandler Carruth ffab873ed5 Add support for warning on general null pointer expressions of boolean 
type rather than just the literal 'false'. This begins fixing PR9612,
but the message is now wrong. WIP, the cleanup of the messaging is next.

Chris Lattner af1bccec68 Fix a bug where RecursivelyDeleteTriviallyDeadInstructions could 
delete the instruction pointed to by CGP's current instruction
iterator, leading to a crash on the testcase.  This fixes PR9578.

Chris Lattner cfe5aa65d2 Avoid excess precision issues that lead to generating host-compiler-specific code. 
Switch lowering probably shouldn't be using FP for this.  This resolves PR9581.

Eli Friedman 17822fcde9 PR9604; try to deal with RAUW updates correctly in the AST. I'm not convinced 
it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

Chris Lattner e53c95f180 fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which 
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

they thought they were, because alternation was expanding
wrong in {{}}'s.

Jakob Stoklund Olesen ed47ed4e80 Build the Hopfield network incrementally when splitting global live ranges. 
It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

Jakob Stoklund Olesen 4ad6c160a5 Precompute interference for neighbor blocks as long as there is no interference. 
This doesn't require seeking in the live interval union, so it is very cheap.

Sean Callanan 1426351c83 Redirected errors from the AsmParser to the proper

Caroline Tice 25d61ac2ed Fix various things in the instruction emulation code: 
- Add ability to control whether or not the emulator advances the
    PC register (in the emulation state), if the instruction itself
    does not change the pc value..

    - Fix a few typos in asm description strings.

    - Fix bug in the carry flag calculation.

Ted Kremenek f603f3afbd Start overhauling static analyzer support for C++ constructors. The inlining support isn't complete, and needs 
to be reworked to model CallEnter/CallExit (just like all other calls).  For now, treat constructors mostly
like other function calls, making the analysis of C++ code just a little more useful.
