Chris Lattner 19083a4671 switch the VRBaseMap in the scheduler from an std::map to a DenseMap. This
speeds up the isel pass from 2.5570s to 2.4722s on kc++ (3.4%).

2006-10-14 08:34:06 +00:00
Evan Cheng 45fe3bc72c Added support for machine specific constantpool values. These are useful for
representing expressions that can only be resolved at link time, etc.

Chris Lattner af23f9b5f6 Completely eliminate def&use operands. Now a register operand is EITHER a
def operand or a use operand.

2006-09-05 02:31:13 +00:00
Chris Lattner d86418ab20 switch the SUnit pred/succ sets from being std::sets to being smallvectors.
This reduces selectiondag time on kc++ from 5.43s to 4.98s (9%).  More
significantly, this speeds up the default ppc scheduler from ~1571ms to 1063ms,
a 33% speedup.

Jim Laskey c3d341ea98 Ensure that dump calls that are associated with asserts are removed from
non-debug build.

Evan Cheng 55772ccfd6 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.

Chris Lattner 957cb6733a Move function-live-in-handling code from the sdisel code to the scheduler.
This code should be emitted after legalize, so it can't be in sdisel.

Note that the EmitFunctionEntryCode hook should be updated to operate on the
DAG.  The X86 backend is the only one currently using this hook.

Owen Anderson 8c2c1e90c4 Refactor a bunch of includes so that TargetMachine.h doesn't have to include
TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

Evan Cheng 095c9d9b7f Duh. That could take a long time.

Evan Cheng afed73eebe Add capability to scheduler to commute nodes for profit.
If a two-address code whose first operand has uses below, it should be commuted
when possible.

Evan Cheng d38c22bdd3 Refactor scheduler code. Move register-reduction list scheduler to a
separate file. Added an initial implementation of top-down register pressure
reduction list scheduler.

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.
This fixes PR 759.

Nate Begeman 4ca2ea5b43 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.
