Initial support for multi-result patterns:

1. [(set GR32:$dst, (add GR32:$src1, GR32:$src2)), (modify EFLAGS)] This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS. 2. def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()> Similar to #1 except this is used for def : Pat patterns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41897 91177308-0d34-0410-b5e6-96231b3b80d8

Allow set operators with multiple destinations, i.e. (set x, y, (op a, b)).

TableGen no longer emit CopyFromReg nodes for implicit results in physical

Always check the type of node. This prevents situations such as selecting 32-bit rotate target instruction for a 64-bit node when 64-bit pattern is missing.

Make use of the llvm-ld tool's new ability to read input from stdin to extract

the list of link time passes to be run, just as for opt, with the -debug-pass=Arguments option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41040 91177308-0d34-0410-b5e6-96231b3b80d8

Now that llvm-ld can accept - as input from stdin, use this feature to extract
