Alexandros Lamprineas	73895c4cf0	[ARM] Emit trap instruction using .inst directive ... The trap instruction is emitted as a data-in-text rather than an instruction. This patch uses the .inst directive for emitting trap. Differential Revision: http://reviews.llvm.org/D16684 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@259182 91177308-0d34-0410-b5e6-96231b3b80d8	2016-01-29 10:23:32 +00:00
Dimitry Andric	ac6a87b06e	Fix several accidental DOS line endings in source files ... Summary: There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings. There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

Oleg Ranevskyy	f1c16763a7	[ARM CodeGen] @llvm.debugtrap call may be removed when restoring callee saved registers ... Summary: When ARMFrameLowering::emitPopInst generates a "pop" instruction to restore the callee saved registers, it checks if the LR register is among them. If so, the function may decide to remove the basic block's terminator and replace it with a "pop" to the PC register instead of LR. This leads to a problem when the block's terminator is preceded by a "llvm.debugtrap" call. The MI iterator points to the trap in such a case, which is also a terminator. If the function decides to restore LR to PC, it erroneously removes the trap.
