Summary: The previous calling convention prevented custom functions from being able to access argument labels unless it knew how many variadic arguments there were, and of which type. This restriction made it impossible to correctly model functions in the printf family, as it is legal to pass more arguments than required to those functions. We now pass arguments in the following order: non-vararg arguments labels for non-vararg arguments [if vararg function, pointer to array of labels for vararg arguments] [if non-void function, pointer to label for return value] vararg arguments Differential Revision: http://reviews.llvm.org/D6028 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220906 91177308-0d34-0410-b5e6-96231b3b80d8
