2009-08-15Fix for PR4721: adjust CodeGen and ASTContext so that we have a Eli Friedman
consistent model for handling size expressions for VLAs. The model is essentially as follows: VLA types own their associated expression. In some cases, we need to create multiple VLA types to represent a given VLA (for canonical types, or qualifiers on array types, or type merging). If we need to create multiple types based off of the same VLA declaration, we use the new refcounting functionality so they can all own the expression. The VLASizeMap in CodeGenFunction then uses the size expression to identify the group of VLA types based off of the same original declaration. I'm not particularly attached to the VLA types owning the expression, but we're stuck with at least until someone comes up with a way to walk the VLA expressions for a declaration. I did the parallel fix in ASTContext for DependentSizedArrayType, but I haven't really looked closely at it, so there might still be issues there. I'll clean up the code duplication in ASTContext in a followup commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79071 91177308-0d34-0410-b5e6-96231b3b80d8

virtual base primaries and improve the layout of classes with virtual bases. WIP. Hey, I've decided I want a change to FileCheck, I need to ensure that the group is together, nothing in between. Can we change it to check the match line is from the line immediately following the last matched line, if the source for the matched line is immediately after the source for the previously matched line? // CHECK: 1 // CHECK: 2 // CHECK: 3 // CHECK: 4 // CHECK: 5 // CHECK: 6 would require 1 2 and 3 to be continuous in the output, and 4 5 and 6 to be continuous. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78638 91177308-0d34-0410-b5e6-96231b3b80d8
