compiler/simplify_goal_conj.m:
When a switch on a variable is followed by a switch on the *same* variable,
merge the two switches together, if doing so looks like it can save
the execution of some branches for at least some input values.
This transform is the second one to merge the goal following a switch
into the switch itself. Move the parts of the code involved that are
common between the two transformation to its caller, to reduce runtime
overhead.
compiler/simplify_goal.m:
Add infrastructure for printing the pre- and post-simplification versions
of specific goals. This helped debug the new code in simplify_goal_conj.m.
Fix an inadvertent unification between two module_infos.
This was caused by code that
- defined the variable ModuleInfo, and then
- reuses the "ModuleInfo" variable name for a slightly different purpose,
but did so in the condition of an if-then-else, where the semidet nature
of the implicit unification between the new value intended to be assigned
to ModuleInfo, and its old value, was expected.
compiler/simplify_proc.m:
Add infrastructure for printing versions of the procedure body
before and after quantification, instmap delta recomputation, and
determinism analysis have been rerun. This helped debug the new code
in simplify_goal_conj.m.
The rest of the changes concern the option that
- previously called only for the existing transformation to merge a test
unification following a switch into a switch
- and which now also calls for the merging of two succesive switches
on the same variable.
compiler/options.m:
The option was named test_after_switch; this diff updates its name to
merge_code_after_switch.
compiler/handle_options.m:
compiler/simplify_info.m:
compiler/simplify_tasks.m:
