Ted Kremenek 2c71d51513 Added initial hacked support for display path diagnostics with 
GRSimpleVals warnings.  Cleaning up, but now we get multiple bubbles (branches are annotated).

Ted Kremenek cb75937198 Added special handling when the build command is "gcc", "cc", or "llvm-gcc"; 
in these cases we directly call ccc-analyzer.

Dale Johannesen fd967cf3fa Recommitting EH patch; this should answer most of the 
review feedback.
-enable-eh is still accepted but doesn't do anything.
EH intrinsics use Dwarf EH if the target supports that,
and are handled by LowerInvoke otherwise.
The separation of the EH table and frame move data is,
I think, logically figured out, but either one still
causes full EH info to be generated (not sure how to
split the metadata correctly).
MachineModuleInfo::needsFrameInfo is no longer used and
is removed.

Evan Cheng ac38d444e2 1. Drop default inline threshold back down to 200. 
2. Do not use # of basic blocks as part of the cost computation since it doesn't really figure into function size.
3. More aggressively inline function with vector code.

Steve Naroff 257520b1b4 Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl). 
- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

llvm-svn: 49042
 2008-04-01 18:04:30 +00:00
Chris Lattner 6f2ffdb73f Change the MemoryBuffer::getFile* methods to take just a pointer to the 
start of a filename, not a filename+length.  All clients can produce a
null terminated name, and the system api's require null terminated 
strings anyway.

Chris Lattner 4c5e15f7da Implement Path::MapInFilePages/UnMapFilePages on unix, which

Chris Lattner 47448288ee MemoryBuffer::getFile got smarter, obviating the need for readfilefast. 
The new MemoryBuffer doesn't "leak" file descriptors and handles the
small file case efficiently.

llvm-svn: 49032
 2008-04-01 06:06:37 +00:00
Chris Lattner a542518315 Reimplement MemoryBuffer::getFile with three enhancements: 
1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
   read the file.
3) otherwise fallback to read.

When sys::path::MapInFilePages is implemented, this provides
several benefits:

#1: this avoids fragmenting memory for small files.
#2: this avoids extraneous stat calls when the file size is known.
#3: this only keeps the file descriptor open while reading the 
    file, not for the duration of the lifetime of the memory 
    buffer.  This fixes a serious clang FD 'leak' problem.

I believe that this will work on a win32 machine, but I don't have
one to test on.  I'd appreciate it if someone could check.

MemoryBuffer is higher level and more closely matches the model
needed.

Chris Lattner 314a1414d0 Change DiffFilesWithTolerance to be written in terms of MemoryBuffer, 
not an mmapped file.  This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.
