All changes are uniform and done with the same script, so checking only some should suffice. For that reason, any tests involving multiple files or custom CLI flags are not included in this commit. Change-Id: Ib2d0e08937b56e241d99771a58aad34ed3ad308a

# Check that stack frame deduplication only affects consecutive intervals, and
|
|
# that they are reported independently of any preceding sections, even if
|
|
# they're indistinguishable.
|
|
#
|
|
# In terms of the current implementation, we check that we clear the set of
|
|
# "seen frames" after eliding a group of frames.
|
|
#
|
|
# Suppose we have:
|
|
# - 10 frames in a function A
|
|
# - 10 frames in a function B
|
|
# - 10 frames in a function A
|
|
#
|
|
# We want to output:
|
|
# - a few frames of A (skip the rest)
|
|
# - a few frames of B (skip the rest)
|
|
# - a few frames of A (skip the rest)
|
|
#
|
|
# If we implemented this in the naive manner, we'd instead get:
|
|
# - a few frames of A (skip the rest)
|
|
# - a few frames of B (skip the rest, _and_ skip the remaining frames of A)
