Evan Cheng 47c9750f04 Do not fold away subreg_to_reg if the source register has a sub-register index. That means the source register is taking a sub-register of a larger register. e.g. On x86 
%RAX<def> = ...
%RAX<def> = SUBREG_TO_REG 0, %EAX:3<kill>, 3
The first def is defining RAX, not EAX so the top bits were not zero-extended.

Chris Lattner fb95472123 When we restore signal handlers, restore them back to what they 
were when we came around, not to their default handler.  This 
should fix PR3848

Sebastian Redl 3b27be6ceb Recognize rvalue references in C++03, but complain about them. This leads to far better error recovery.

Eli Friedman 80160bd483 Partial implementation of PR3342: break out pointer sign 
incompatibilities in assignments from other pointer incompatibilities.  
Based off of the patch in PR3342.  (This doesn't implement -Wno-pointer-sign,
but I don't know the driver code very well.)

Daniel Dunbar a0c89be9cc Driver: Drop code for checking bounds in SeparateArg::render, this 
situation should never occur now that arguments are parsed correctly.

Eli Friedman e8dd7b3228 Adjust isModifiableLvalue to give a slightly more useful diagnostic for 
attempting to illegally modify a BlockDeclRefExpr.

Daniel Dunbar d8500f3b0f Driver: Implement 'missing argument' error. 
llvm-svn: 67490
 2009-03-22 23:26:43 +00:00
Eli Friedman 7fa3faa417 Fix code to mark block variables as const to actually work. Fix 
isObjCObjectPointerType to work with qualified types.  Adjust test for 
changes.

If the SemaExpr changes are wrong or break existing code, feel free to 
delete the "ExprTy.addConst();" line and revert my changes to 
test/Sema/block-literal.c.

Chris Lattner e64911a4ae switch getBuiltinLibFunction to use the new GetOrCreateLLVMFunction 
functionality, fixing a crash on the attached testcase.  Eliminate the
BuiltinFunctions cache, as it can contain dangling pointers.  This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

Chris Lattner 75acb0c356 fix a fixme: non-proto struct returning function definitions should be compiled 
to something like:
define void @bar(%struct.foo* noalias sret %agg.result) nounwind {
instead of:
define void @bar(%struct.foo* noalias sret %agg.result, ...) nounwind {

Bill Wendling a443ab4bcd Really should pass -dylib to the linker... 
llvm-svn: 67469
 2009-03-22 08:56:15 +00:00
Bill Wendling f3ef2c758f A dylib should be built as a dylib and not a bundle.

Ted Kremenek dc637a0be9 PTHManager::Create(): 
- Make the Diagnostic::Level for PTH errors to be specified by the caller

clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
  (a hard error) and Diagnostic::Warning for -token-cache (we can still
  proceed).

Anders Carlsson 7cbd8fb6b0 Keep track of whether a class is abstract or not. This is currently only used for the __is_abstract type trait.

Chris Lattner e09ad90882 don't set the name of a call instruction to "call" in release-asserts 
build.  This shaves another 3% off.

 2009-03-22 00:32:22 +00:00
Chris Lattner 47640221da fix CreateTempAlloca to not set a name on the alloca for temporaries 
in release-assert builds.  For automatic variables, explicitly set
a name with setName that does not make a temporary std::string.

This speeds up -emit-llvm-only -disable-free on PR3810 by 4.6%

llvm-svn: 67459
 2009-03-22 00:24:14 +00:00

llvm-svn: 67458
 2009-03-22 00:18:18 +00:00
Chris Lattner 4ff71de880 set function/global names with setName instead of passing the name into the 
ctor function.  This avoids creating a temporary std::string for the name,
speeding up the testcase in PR3810 by 3.8%

llvm-svn: 67457
