This change actually migrates vm/dart/* tests to NNBD by fixing compile-time errors and adjusting tests where needed. vm/dart/null_float32x4_simd_ops_test and vm/dart/null_float64x2_simd_ops_test are deleted as they are superseded by static type checks. vm/dart/regress_40462_test.dart is a huge source code auto-generated by fuzzer and migrating and maintaining this source doesn't have much value, so it is deleted. There are still failures in strong mode due to dependencies on the packages which are not migrated yet (https://github.com/dart-lang/sdk/issues/42146). Migrated vm/dart/null_checks_with_dwarf_stack_traces_test fails both in weak and strong mode due to https://github.com/dart-lang/sdk/issues/42149.

// This test tries to verify that we produce the correct stack trace when
|
|
// throwing exceptions even when functions are inlined.
|
|
// The test invokes a bunch of functions and then does a throw. There is a
|
|
// catch at the outer function which uses the stack trace produced to return
|
|
// a string. The test then verifies that the stack trace contains each
|
|
// method in the invocation chain. The test is run during warmup to ensure
|
|
// unoptimized code produces the correct result and is then run
|
|
// in a loop to ensure optimization kicks in and some inlining is done.
|
|
// Note: it appears that functions which have a throw are not inlined (func4)
|
|
// and functions that have try/catch in them are not optimized (func1).
|
|
// func2 is not inlined as func1 has not been optimized.
