*	Add Forward Control-Flow Integrity.	Tom Roeder	2014-11-11	1	-32/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This commit adds a new pass that can inject checks before indirect calls to make sure that these calls target known locations. It supports three types of checks and, at compile time, it can take the name of a custom function to call when an indirect call check fails. The default failure function ignores the error and continues. This pass incidentally moves the function JumpInstrTables::transformType from private to public and makes it static (with a new argument that specifies the table type to use); this is so that the CFI code can transform function types at call sites to determine which jump-instruction table to use for the check at that site. Also, this removes support for jumptables in ARM, pending further performance analysis and discussion. Review: http://reviews.llvm.org/D4167 llvm-svn: 221708

*	Add a new attribute called 'jumptable' that creates jump-instruction tables ↵	Tom Roeder	2014-06-05	1	-0/+32
	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
