// 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.
