11 years agoStart scaffolding for a MachineTraceMetrics analysis pass.
Jakob Stoklund Olesen [Thu, 26 Jul 2012 18:38:11 +0000 (18:38 +0000)]
Start scaffolding for a MachineTraceMetrics analysis pass.

This is still a work in progress.

Out-of-order CPUs usually execute instructions from multiple basic
blocks simultaneously, so it is necessary to look at longer traces when
estimating the performance effects of code transformations.

The MachineTraceMetrics analysis will pick a typical trace through a
given basic block and provide performance metrics for the trace. Metrics
will include:

- Instruction count through the trace.
- Issue count per functional unit.
- Critical path length, and per-instruction 'slack'.

These metrics can be used to determine the performance limiting factor
when executing the trace, and how it will be affected by a code
transformation.

Initially, this will be used by the early if-conversion pass.

Preserve 2-addr constraints in ConnectedVNInfoEqClasses.

arbitrarily assign <undef> uses to component 0. This is wrong when the
use is tied to a def that gets assigned to a different component:
