git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41218 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-21Split complex arithmetic codegen out from aggregate codegen.Chris Lattner
This means that we get rid of tons of intermediate allocas. For example: void foo(double _Complex a, double _Complex b) { a = b+a+a; } this used to have 4 temporary allocas, now it has zero of them. This also simplifies the individual visitor methods because they now can all operate on real/imag pairs instead of having to load/store all over the place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41217 91177308-0d34-0410-b5e6-96231b3b80d8

match on binop then explicitly switching again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41214 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-21switch aggregate expr codegen to use a visitor to localize most of the nasty Chris Lattner
details in its own file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41213 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41188 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-20Modified ArraySubscriptExpr to have accessors getLHS and getRHS in additionTed Kremenek
to getBase and getIdx. getBase and getIdx now return a "normalized" view of the expression (e.g., always "A[4]" instead of possibly "4[A]"). getLHS and getRHS return the expressions with syntactic fidelity to the original source code. Also modified client code of ArraySubscriptExpr, including the AST dumper and pretty printer, the return-stack value checker, and the LLVM code generator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41180 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-11start splitting out aggregate value computation from EmitExpr into EmitAggExpr.Chris Lattner
aggregate value and scalar expression computation are very different, this gets them away from each other. This causes a temporary regression on some complex number examples. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41014 91177308-0d34-0410-b5e6-96231b3b80d8

struct X { int A; }; void foo() { struct X s; int i; i = __builtin_choose_expr(0, s, i); } compiles to: %tmp = load i32* %i ; <i32> [#uses=1] store i32 %tmp, i32* %i wow :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40801 91177308-0d34-0410-b5e6-96231b3b80d8
