2009-08-11Implement more of the inductive case for vtable layout involvingMike Stump
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

Fixes PR4704 problems Addresses Eli's patch feedback re: ugly cast code Updates all postfix operators to remove ParenListExprs.
