90a25bcd6f Ugly hack! Add helper functions InsertInFlightSetEntry and
RemoveInFlightSetEntry. They are used in place of direct set operators to
reduce instruction selection function stack size.

093d9771df Fix an error message regression. Print:
LI8:    (LI8:i64 (imm:i64):$imm)
instead of:
  LI8:    (LI8:MVT::i64 (imm:MVT::i64):$imm)

88f2956ac8 Don't require src/dst patterns to be able to fully resolve their types,
because information about one can help refine the other.  This allows us to
write:

def : Pat<(i32 (extload xaddr:$src, i8)),
          (LBZX xaddr:$src)>;

as:

def : Pat<(extload xaddr:$src, i8),
          (LBZX xaddr:$src)>;

because tblgen knows LBZX returns i32.

25273f71bf Make sure to use the result of the pattern to infer the result type of the
instruction, and the result type of the instruction to refine the pattern.
This allows us to write things like this:

def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (v2i64 VR128:$src)>;

as:
def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)>

and fixes a ppc64 issue.

07d8ccec50 Instructions with variable operands (variable_ops) can have a number required
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

1e9556ee06 Can't trust NodeDepth when checking for possibility of load folding creating
a cycle. This increase the search space and will increase compile time (in
practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec)
that will be addressed later.

2a4c04d35a Fixed a really ugly bug. The TableGen'd isel is not freeing the "inflight set"
correctly. That is causing non-deterministic behavior (and possibly preventing
some load folding from happening).

accb9d0378 Now that iPTR is a fully resolved type. We end up losing the type check for
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

2af8a9f980 Watch out for the following case:
1. Use expects a chain output.
2. Node is expanded into multiple target ops.
3. One of the inner node produces a chain, the outer most one doesn't.

7ed816f900 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
