Begin adding docs and IR-level support for the inalloca attribute The inalloca attribute is designed to support passing C++ objects by value in the Microsoft C++ ABI. It behaves the same as byval, except that it always implies that the argument is in memory and that the bytes are never copied. This attribute allows the caller to take the address of an outgoing argument's memory and execute arbitrary code to store into it. This patch adds basic IR support, docs, and verification. It does not attempt to implement any lowering or fix any possibly broken transforms. When this patch lands, a complete description of this feature should appear at http://llvm.org/docs/InAlloca.html . Differential Revision: http://llvm-reviews.chandlerc.com/D2173 llvm-svn: 197645

The 'optnone' attribute means don't inline anything into this function (except functions marked always_inline). Functions with 'optnone' must also have 'noinline' so they don't get inlined into any other function. Based on work by Andrea Di Biagio. llvm-svn: 195046

Add a new attribute called 'jumptable' that creates jump-instruction tables for functions marked with this attribute. It includes a pass that rewrites all indirect calls to jumptable functions to pass through these tables. This also adds backend support for generating the jump-instruction tables on ARM and X86. Note that since the jumptable attribute creates a second function pointer for a function, any function marked with jumptable must also be marked with unnamed_addr. llvm-svn: 210280
