*	Change the fast-isel-abort option from bool to int to enable "levels"	Mehdi Amini	2015-02-27	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

*	[FastISel][AArch64] Fix an incorrect kill flag due to a bug in SelectTrunc.	Juergen Ributzka	2014-08-29	1	-0/+12
	When we select a trunc instruction we don't emit any code if the type is already i32 or smaller. This is because the instruction that uses the truncated value will deal with it. This behavior can incorrectly transfer a kill flag, which was meant for the result of the truncate, onto the source register. %2 = trunc i32 %1 to i16 ... = ... %2 -> ... = ... vreg1 <kill> ... = ... %1 ... = ... vreg1 This commit fixes this by emitting a COPY instruction, so that the result and source register are distinct virtual registers. This fixes rdar://problem/18178188. llvm-svn: 216750
