2009-02-13Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor
ABI to the CodeGen library. Since C++ code-generation is so incomplete, we can't exercise much of this mangling code. However, a few smoke tests show that it's doing the same thing as GCC. When C++ codegen matures, we'll extend the ABI tester to verify name-mangling as well, and complete the implementation here. At this point, the major client of name mangling is in the uses of the new "overloadable" attribute in C, which allows overloading. Any "overloadable" function in C (or in an extern "C" block in C++) will be mangled the same way that the corresponding C++ function would be mangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64413 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59936 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-12Move EmitBranchOnBoolExpr and ConstantFoldsToSimpleInteger toChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59113 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11Rework IRgen invariant w.r.t. current insert point.Daniel Dunbar
- 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! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59089 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-11short circuit && and || when possible. This substantially reducesChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59034 91177308-0d34-0410-b5e6-96231b3b80d8
