Reimplement rip-relative addressing in the X86-64 backend. The new implementation primarily differs from the former in that the asmprinter doesn't make a zillion decisions about whether or not something will be RIP relative or not. Instead, those decisions are made by isel lowering and propagated through to the asm printer. To achieve this, we: 1. Represent RIP relative addresses by setting the base of the X86 addr mode to X86::RIP. 2. When ISel Lowering decides that it is safe to use RIP, it lowers to X86ISD::WrapperRIP. When it is unsafe to use RIP, it lowers to X86ISD::Wrapper as before. 3. This removes isRIPRel from X86ISelAddressMode, representing it with a basereg of RIP instead. 4. The addressing mode matching logic in isel is greatly simplified. 5. The asmprinter is greatly simplified, notably the "NotRIPRel" predicate passed through various printoperand routines is gone now. 6. The various symbol printing routines in asmprinter now no longer infer when to emit (%rip), they just print the symbol. I think this is a big improvement over the previous situation. It does have two small caveats though: 1. I implemented a horrible "no-rip" modifier for the inline asm "P" constraint modifier. This is a short term hack, there is a much better, but more involved, solution. 2. I had to xfail an -aggressive-remat testcase because it isn't handling the use of RIP in the constant-pool reading instruction. This specific test is easy to fix without -aggressive-remat, which I intend to do next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74372 91177308-0d34-0410-b5e6-96231b3b80d8 2009-06-27 04:16:01 +00:00			`define i32 @f() nounwind {`
