Mikhail Glukhikh	b0ec3cb831	Switch off FIR version off REDUNDANT_LABEL_WARNING (performance-related) ... This reverts commit 363b2550 (partially)	2021-10-27 12:26:59 +03:00
Tianyu Geng	363b25504d	FIR checker: report REDUNDANT_LABEL_WARNING ... Since many labels are not present in the FIR tree, this checker is implemented as a syntax checker. Comparing with FE1.0, this change reports some REDUNDANT_LABEL_WARNING that FE1.0 has missed, especially LHS of assignments.	2021-10-25 13:51:01 +03:00
Tianyu Geng	c7272f6986	FIR checker: SENSELESS_(COMPARISON|NULL_IN_WHEN) ... Currently DFA does not set "definitely equal to null" for access to variables that got assigned `null`. For example, FIR should mark the following line as SENSELESS_COMPARISON due to `s = null` above. https://github.com/JetBrains/kotlin/blob/d1531f9cdd5852352c0133198706125dc63b6007/compiler/testData/diagnostics/tests/smartCasts/alwaysNull.fir.kt#L6 The problem is at https://github.com/JetBrains/kotlin/blob/7e9f27436a77de1c76e3705da7aa1fbe8938336b/compiler/fir/resolve/src/org/jetbrains/kotlin/fir/resolve/dfa/FirDataFlowAnalyzer.kt#L1104 For null assignment, ideally the type should be `Nothing?`. This is addressed in a followup commit instead.	2021-08-06 22:57:16 +03:00
