 2007-12-06 20:10:20 +00:00
Fariborz Jahanian 227c0d13bc On Steve's suggestion, moved handling of use of undeclared method in a message 
to rewriter (my previous patch).

Devang Patel 65a2288eef More struct bitfields layout work. Now handle, 
struct STestB1 {char a; char b:2; } stb1;
struct STestB2 {char a; char b:5; char c:4} stb2;

Simpler and safer.

Evan Cheng 8393dc7378 Turning simple splitting on. Start testing new coalescer heuristics as new llcbeta.

Chris Lattner eedaf92fcf third time around: instead of disabling this completely, 
only disable it if we don't know it will be obviously profitable.
Still fixme, but less so. :)

Chris Lattner b5fdfb9612 Actually, disable this code for now. More analysis and improvements to 
the X86 backend are needed before this should be enabled by default.

Chris Lattner 7c709a5d08 implement a readme entry, compiling the code into: 
_foo:
	movl	$12, %eax
	andl	4(%esp), %eax
	movl	_array(%eax), %eax
	ret

instead of:

_foo:
	movl	4(%esp), %eax
	shrl	$2, %eax
	andl	$3, %eax
	movl	_array(,%eax,4), %eax
	ret

As it turns out, this triggers all the time, in a wide variety of
situations, for example, I see diffs like this in various programs:

-       movl    8(%eax), %eax
-       shll    $2, %eax
-       andl    $1020, %eax
-       movl    (%esi,%eax), %eax
+       movzbl  8(%eax), %eax
+       movl    (%esi,%eax,4), %eax


-       shll    $2, %edx
-       andl    $1020, %edx
-       movl    (%edi,%edx), %edx
+       andl    $255, %edx
+       movl    (%edi,%edx,4), %edx

Unfortunately, I also see stuff like this, which can be fixed in the
X86 backend:

-       andl    $85, %ebx
-       addl    _bit_count(,%ebx,4), %ebp
+       shll    $2, %ebx
+       andl    $340, %ebx
+       addl    _bit_count(%ebx), %ebp

Chris Lattner 7f3587e344 add a new ExecutionEngine::createJIT which can be used if you only want 
to create a JIT.  This lets you specify JIT-specific configuration items
like the JITMemoryManager to use.

Ted Kremenek 260d01d6e6 Subdivided the function InitializeBaseLanguage into InitializeBaseLanguage, 
GetLanguage, and InitializeLangOptions.  The goal is to break up this logic
into atomic units of functionality that can later be refactored into better
driver logic that is capable of handling a mixture of source files of
different languages.

Chris Lattner 55d8c3f71b split the JIT memory management code out from the main JIT logic into its 
own JITMemoryManager interface.  There is no functionality change with 
this patch.

Steve Naroff 152dd812b2 Make sure Parser::ParseObjCSelectorExpression() handles unary selectors (with no arguments) properly. 
llvm-svn: 44636

Ted Kremenek cdcf6dcbcb Removed dependence on including iostream (use llvm/Support/Streams.h instead).

Ted Kremenek e095881856 Converted SerializationTest (--test-pickling) to use the new TranslationUnit 
class to serialize and deserialize translation units.

 2007-12-05 22:08:43 +00:00
Steve Naroff ff9f8efe4d Make sure the class methods get attached to the metaclass object. 
Need to query the implementation, not the interface...

llvm-svn: 44633
 2007-12-05 21:49:40 +00:00
Ted Kremenek 68d232b477 Added Driver/TranslationUnit.h and Driver/TranslationUnit.cpp to the 
XCode project.

llvm-svn: 44632
 2007-12-05 21:36:57 +00:00
Ted Kremenek 62f4302ec7 Added "TranslationUnit" class that will be used to provide an interface 
for serializing/deserializing ASTs that is decoupled from the logic
in SerializationTest (which will soon be rewritten to use this interface).

llvm-svn: 44631
 2007-12-05 21:36:08 +00:00
Ted Kremenek dd1a7aade5 Modified: CreateTargetInfo(). Now takes Diagnostic* instead of Diagnostic&. 
Modified: ctor of SerializationTest: Now takes LangOptions argument.  We
          will eventually serialize this as well.

Ted Kremenek a4c13bd94b Moved creation of ASTConsumers that can operate on both freshly-parsed and 
deserialized ASTs into the function CreateASTConsumer().  This function
is called by ProcessInputFile, and soon the logic that processes deserialized
ASTs.
