* Thread CGFunctionInfo construction through CodeGenTypes.Daniel Dunbar2009-02-021-1/+1

* More ABI API cleanup.Daniel Dunbar2009-02-021-2/+4
| | | | | | | - Lift CGFunctionInfo creation above ReturnTypeUsesSret and EmitFunction{Epi,Pro}log. llvm-svn: 63553

* Make sure to generate code for arguments that have a variably modified type.Anders Carlsson2008-12-201-0/+10
| | | | llvm-svn: 61288
* Change EmitVLASize to take a QualType that must be a variably modified type.Anders Carlsson2008-12-201-21/+32
| | | | | | | | | | | | Emit the size even if the declared type is a variably modified type. This lets us handle void f(int n) { int (*a)[n]; printf("size: %d\n", sizeof(*a)); } llvm-svn: 61285

* Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make itChris Lattner2008-11-241-1/+2
| | | | | | | | | assert if the name is not an identifier. Update callers to do the right thing and avoid this method in unsafe cases. This also fixes an objc warning that was missing a space, and migrates a couple more to taking IdentifierInfo and QualTypes instead of std::strings. llvm-svn: 59936
* An expression is not foldable if it can't be fully evaluated. Fixes PR3060Anders Carlsson2008-11-221-2/+4

* Introduction the DeclarationName class, as a single, general method ofDouglas Gregor2008-11-171-1/+1
| | | | | | | | representing the names of declarations in the C family of languages. DeclarationName is used in NamedDecl to store the name of the declaration (naturally), and ObjCMethodDecl is now a NamedDecl. llvm-svn: 59441
* rename Expr::tryEvaluate to Expr::Evaluate.Chris Lattner2008-11-161-1/+1
| | | | llvm-svn: 59426
* Normalize many BasicBlock names.Daniel Dunbar2008-11-131-2/+2
| | | | | | | | | | - Use dotted notation for blocks related to a particular statement type. - Use .end for landing pads. No functionality change in NDEBUG mode. :) llvm-svn: 59210
* Quick fix for crash in IRgen when we can tryEvaluate a condition toDaniel Dunbar2008-11-121-2/+5
| | | | | | | | | something that is not an int. - Ignore these cases for now, added FIXME that we should also boolize them. llvm-svn: 59184

* Move EmitBranchOnBoolExpr and ConstantFoldsToSimpleInteger toChris Lattner2008-11-121-0/+85
| | | | | | | | | | CodeGenFunction.cpp. Change VisitConditionalOperator to use constant fold instead of codegen'ing a constant conditional. Change ForStmt to use EmitBranchOnBoolExpr, this shrinks expr.c very slightly to 40239 lines. llvm-svn: 59113
* Rework IRgen invariant w.r.t. current insert point.Daniel Dunbar2008-11-111-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - EmitStmt is no longer required to finish with a current insertion point defined (i.e. it does not need to make dummy blocks). Instead, it can clear the insertion point in the builder which indicates that the current insertion point is unreachable. - CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint which respectively test if there is an insert point and ensure an insertion point exists (by making a dummy block). - Clearly mark functions in CodeGenFunction which can be called with no insertion point defined. Currently this is a limited set, and EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR. Remove EmitDummyBlock, which is no longer needed. Clients who haven't already cleared the insertion point (typically via EmitBranch) can do so by hand. Remove isDummyBlock, which has effectively been renamed to HaveInsertPoint. The main thrust of this change is that we no longer have create dummy blocks just to destroy them a short time later in EmitBlock in the common case that there is no unreachable code following something like a goto. Additionally, this means that we are not using the hokey condition in isDummyBlock that a block without a name is a dummy block. Guess how well that works when we never emit block names! llvm-svn: 59089
* Emit debug region end in unified return block.Daniel Dunbar2008-11-111-6/+7

* short circuit && and || when possible. This substantially reducesChris Lattner2008-11-111-0/+30
| | | | | | | | the size of the -O0 output on some cases. For example, on expr.c from 176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed references to two external symbols. llvm-svn: 59034
* Remove CodeGenFunction::StartBlock.Daniel Dunbar2008-11-111-10/+0
| | | | | | - Was confusing and only used in one small part of the code. llvm-svn: 59020
* Centralize basic block creation in CodeGenFunction::createBasicBlock.Daniel Dunbar2008-11-111-5/+5
| | | | | | - No functionality change. llvm-svn: 59017
* Implement lowering of va_arg in clang directly. (This is 32-bit X86 only for ↵Anders Carlsson2008-11-041-0/+35

* Don't run the verifier as part of IRgen, this is now down (per module)Daniel Dunbar2008-10-281-7/+0
| | | | | | in the driver (this means we no longer run the verifier per function, however). llvm-svn: 58307
* Debug info bug fix, function start wasn't getting generated correctlyDaniel Dunbar2008-10-181-7/+12
| | | | | | for Obj-C methods. llvm-svn: 57769
* Change CGDebugInfo::setLocation to just ignore invalid locations. ThisDaniel Dunbar2008-10-171-6/+2
| | | | | | | | | simplifies clients. Also, add assert that RegionStack is empty when the CGDebugInfo is destroyed. llvm-svn: 57684
