and eliminate dead code. This is meant to be a replacement for the utility:
recursivelyDeleteTriviallyDeadInstructions. The new utility performs more aggresive
dead-code elimination for ownership SIL.
This patch also migrates most non-force-delete uses of
recursivelyDeleteTriviallyDeadInstructions to the new utility.
and migrates one force-delete use of recursivelyDeleteTriviallyDeadInstructions
(in IRGenPrepare) to use the new utility.
of OSLogMessage constant evaluable and remove @_transparent annotation
from the methods. Also, improve diagnostics in the OSLogOptimization
pass as now it rely on seeing the appendInterpolation/Literal calls.
evaluator to precisely evaluate Builtin.assert_configuration.
Unify UnknownReason::Trap and UnknownReason::AssertionFailure error
values in the constant evaluator, now that we have 'condfail_message'
SIL instruction, which provides an error message for the traps.
@_semantics("constant_evaluable") annotation to denote constant
evaluable functions.
Add a test suite that uses the sil-opt pass ConstantEvaluableSubsetChecker.cpp
to check the constant evaluability of function in the OSLog
overlay.
of Swift code snippets. Add a new test: constant_evaluable_subset_test.swift
that tests Swift code snippets that are expected to be constant evaluable and
those that are not.
