2009-01-20Do codegen correctly for va_start/end/copy on architectures where Eli Friedman
va_list is a struct, like x86-64. If anyone has a better idea for how to do the check in the if statements, suggestions are welcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62582 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-20Fix for PR3350: add special-casing for "references" to va_lists in Eli Friedman

2008-10-29Fix for PR2966: va_start/va_end use the *address* of the Eli Friedman
va_list, not the value. Patch fixes an assert on x86-64 and a wrong-code bug on x86. I'm not completely sure, but I think it's a regression from r58306. Does anyone run regression tests regularly on x86-64? The crash should have been picked up there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58366 91177308-0d34-0410-b5e6-96231b3b80d8

it is possible that a builtin could sometimes be folded (e.g. __builtin_clz) if it's operand is a constant. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57161 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-06remove some code where CGBuiltin folds constants, and use tryEvaluate toChris Lattner

- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header.

2008-06-30Make a few related changes:Chris Lattner
1) add a new ASTContext::getFloatTypeSemantics method. 2) Use it from SemaExpr.cpp, CodeGenTypes.cpp and other places. 3) Change the TargetInfo.h get*Format methods to return their fltSemantics byref instead of by pointer. 4) Change CodeGenFunction::EmitBuiltinExpr to allow builtins which sometimes expand specially and othertimes fall back to libm. 5) Add support for __builtin_nan("") to codegen, cases that don't pass in an empty string are currently lowered to libm calls. 6) Fix codegen of __builtin_infl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52914 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-17This patch is motivated by numerous strict-aliasing warnings when compilingTed Kremenek
clang as a Release build. The big change is that all AST nodes (subclasses of Stmt) whose children are Expr* store their children as Stmt* or arrays of Stmt*. This is to remove strict-aliasing warnings when using StmtIterator. None of the interfaces of any of the classes have changed (except those with arg_iterators, see below), as the accessor methods introduce the needed casts (via cast<>). While this extra casting may seem cumbersome, it actually adds some important sanity checks throughout the codebase, as clients using StmtIterator can potentially overwrite children that are expected to be Expr* with Stmt* (that aren't Expr*). The casts provide extra sanity checks that are operational in debug builds to catch invariant violations such as these. For classes that have arg_iterators (e.g., CallExpr), the definition of arg_iterator has been replaced. Instead of it being Expr**, it is an actual class (called ExprIterator) that wraps a Stmt**, and provides the necessary operators for iteration. The nice thing about this class is that it also uses cast<> to type-checking, which introduces extra sanity checks throughout the codebase that are useful for debugging. A few of the CodeGen functions that use arg_iterator (especially from OverloadExpr) have been modified to take begin and end iterators instead of a base Expr** and the number of arguments. This matches more with the abstraction of iteration. This still needs to be cleaned up a little bit, as clients expect that ExprIterator is a RandomAccessIterator (which we may or may not wish to allow for efficiency of representation). This is a fairly large patch. It passes the tests (except CodeGen/bitfield.c, which was already broken) on both a Debug and Release build, but it should obviously be reviewed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52378 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
