811ca3ddba Identify Analysis pass. 
Do not run analysis pass again if analysis info is still available.
This fixes PR1441.

c0ac2481af Check in some #ifdef'd out code switching call argument 
lowering over to SparcCallingConv.td.  We can't make the switch
yet because we can't say to pass f64 registers in 2 x i32 registers
with the td file yet.

5da16e856c A first attempt at updating live intervals, with code lifted from 
the coalescer.  This doesn't really work, but gets us farther than
before.

fa003f7a57 Switch sparc from using LowerCallTo to using LowerOperation(CALL) like 
other targets.  Use autogenerated calling conv to lower result of
calls.

3098125c84 Start moving sparc to use SparcCallingConv.td, switching over 
return lowering first.  This fixes a bug where the top and bottom
of i64 values were returned in the wrong registers before.

best practices.

5aef54c950 refactor the LowerOperation code out to individual functions for 
each lowering, which is 'best practice'.

ee1e5be870 Next round of PPC32 ABI changes. Allow for gcc 
behavior where a callee thinks a param will be
present in memory, even though the ABI doc says
it doesn't have to be.  Handle complex long long
and complex double (4 and 8 return regs).

489493948a All of these tests had out of date syntax and were never even running through 
llvm-upgrade because nobody noticed them failing.

Update to use new syntax and actually check for the right failure by looking at
the error message.

b4f4b41048 Make insert_subreg a two-address instruction, vastly simplifying LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register.
