* Win64: Don't emit unwind info for "leaf" functions (PR30337)Hans Wennborg2016-09-221-2/+2
| | | | | | | | | | | | According to MSDN (see the PR), functions which don't touch any callee-saved registers (including %rsp) don't need any unwind info. This patch makes LLVM not emit unwind info for such functions, to save binary size. Differential Revision: https://reviews.llvm.org/D24748 llvm-svn: 282185
* [X86] Add RIP to GR64_TCW64David Majnemer2015-11-301-0/+16
The MachineVerifier wants to check that the register operands of an instruction belong to the instruction's register class. RIP-relative control flow instructions violated this by referencing RIP. While this was fixed for SysV, it was never fixed for Win64. llvm-svn: 254315
