2016-07-26	[safestack] Fix stack guard live range.	Evgeniy Stepanov	1	-1/+1
	Stack guard slot is live throughout the function. llvm-svn: 276712
2016-06-29	StackColoring for SafeStack.	Evgeniy Stepanov	1	-38/+50
	This is a fix for PR27842. An IR-level implementation of stack coloring tailored to work with SafeStack. It is a bit weaker than the MI implementation in that it does not the "lifetime start at first access" logic. This can be improved in the future. This patch also replaces the naive implementation of stack frame layout with a greedy algorithm that can split existing stack slots and even fit small objects inside the alignment padding of other objects. llvm-svn: 274162
2016-06-23	Fix doubly included header	Matt Arsenault	1	-1/+0
	llvm-svn: 273528
2016-06-16	[safestack] Sink unsafe address computation to each use.	Evgeniy Stepanov	1	-8/+31
	This is a fix for PR27844. When replacing uses of unsafe allocas, emit the new location immediately after each use. Without this, the pointer stays live from the function entry to the last use, while it's usually cheaper to recalculate. llvm-svn: 272969
2016-06-16	[safestack] Fixup llvm.dbg.value when rewriting unsafe allocas.	Evgeniy Stepanov	1	-0/+1
	When moving unsafe allocas to the unsafe stack, dbg.declare intrinsics are updated to refer to the new location. This change does the same to dbg.value intrinsics. llvm-svn: 272968
2016-04-11	[safestack] Add canary to unsafe stack frames	Evgeniy Stepanov	1	-19/+76
	Add StackProtector to SafeStack. This adds limited protection against data corruption in the caller frame. Current implementation treats all stack protector levels as -fstack-protector-all. llvm-svn: 266004
2016-02-02	[safestack] Make sure the unsafe stack pointer is popped in all cases	Anna Zaks	1	-27/+26
	The unsafe stack pointer is only popped in moveStaticAllocasToUnsafeStack so it won't happen if there are no static allocas. Fixes https://llvm.org/bugs/show_bug.cgi?id=26122 Differential Revision: http://reviews.llvm.org/D16339 llvm-svn: 259447
2016-01-27	Move SafeStack to CodeGen.	Benjamin Kramer	1	-0/+760
	It depends on the target machinery, that's not available for instrumentation passes. llvm-svn: 258942
