NAME

PAX::HotRegionJIT - hot-region promotion planner

SYNOPSIS

use PAX::HotRegionJIT;

my $obj = PAX::HotRegionJIT->new(...);
my $result = $obj->decision(...);

DESCRIPTION

Decides when a profiled region is hot enough to justify promotion into a native or JIT-oriented execution path.

METHODS

new, decision, retirement

These are the public entrypoints exposed by this module's current interface.

PURPOSE

This module exists to keep the hot-region promotion planner logic in one place so the CLI, build pipeline, and runtime can reuse the same behavior instead of duplicating it.

WHY IT EXISTS

PAX uses this module when it needs hot-region promotion planner. Keeping that behavior isolated here makes the surrounding compiler and packaging stages easier to reason about and safer to evolve.

WHEN TO USE

Edit this file when a change affects hot-region promotion planner, the data contract this module returns, or the conditions under which callers choose this path.

HOW TO USE

Load the module through the normal PAX call path, pass explicit arguments rather than ambient global state, and keep project-specific behavior out of this file so the implementation stays neutral across arbitrary Perl applications.

WHAT USES IT

This module is used by the PAX CLI, the build pipeline, standalone packaging, and the test suite paths that cover hot-region promotion planner.

EXAMPLES

Example 1:

perl -Ilib -MPAX::HotRegionJIT -e 1

Confirm that the module loads from a source checkout.

Example 2:

prove -lr t

Run the repository test suite after changing the behavior this module owns.
