◆ addMachinePasses()

void TargetPassConfig::addMachinePasses ( )

virtual

Add the complete, standard set of LLVM CodeGen passes.

Add the complete set of target-independent postISel code generator passes.

Fully developed targets will not generally override this.

This can be read as the standard order of major LLVM CodeGen stages. Stages with nontrivial configuration or multiple passes are broken out below in addStage routines.

Any TargetPassConfig::addXX routine may be overriden by the Target. The addPre/Post methods with empty header implementations allow injecting target-specific fixups just before or after major stages. Additionally, targets have the flexibility to change pass order within a stage by overriding default implementation of addStage routines below. Each technique has maintainability tradeoffs because alternate pass orders are not well supported. addPre/Post works better if the target pass is easily tied to a common pass. But if it has subtle dependencies on multiple passes, the target should override the stage instead.

TODO: We could use a single addPre/Post(ID) hook to allow pass injection before/after any target-independent pass. But it's currently overkill.

Add passes that optimize machine instructions after register allocation.

virtual bool llvm::TargetPassConfig::addPreRewrite ( )

inlineprotectedvirtual

addPreRewrite - Add passes to the optimized register allocation pipeline after register allocation is complete, but before virtual registers are rewritten to physical registers.

These passes must preserve VirtRegMap and LiveIntervals, and when running after RABasic or RAGreedy, they should take advantage of LiveRegMatrix. When these passes run, VirtRegMap contains legal physreg assignments for all virtual registers.

◆ createRegAllocPass()

FunctionPass * TargetPassConfig::createRegAllocPass ( bool Optimized )

protected

addMachinePasses helper to create the target-selected or overriden regalloc pass.

Find and instantiate the register allocation pass requested by this target at the current optimization level.

Different register allocators are defined as separate passes because they may require different analysis.

This helper ensures that the regalloc= option is always available, even for targets that override the default allocator.

FIXME: When MachinePassRegistry register pass IDs instead of function ptrs, this can be folded into addPass.

◆ createTargetRegisterAllocator()

FunctionPass * TargetPassConfig::createTargetRegisterAllocator ( bool Optimized )

protectedvirtual

createTargetRegisterAllocator - Create the register allocator pass for this target at the current optimization level.

Instantiate the default register allocator pass for this target for either the optimized or unoptimized allocation path.

This will be added to the pass manager by addFastRegAlloc in the unoptimized case or addOptimizedRegAlloc in the optimized case.

A target that uses the standard regalloc pass order for fast or optimized allocation may still override this for per-target regalloc selection. But -regalloc=... always takes precedence.
