`removeprefix` was only added to Python in March 2020. It isn't available on Python 3.8.2, which is the default macOS Python installed version. https://www.python.org/dev/peps/pep-0616/ Change-Id: I7b8db0dfc55f1448cc72f41ba9a6ad5f099d48ef Reviewed-on: https://skia-review.googlesource.com/c/skia/+/448259 Auto-Submit: John Stiles <johnstiles@google.com> Commit-Queue: Brian Osman <brianosman@google.com> Reviewed-by: Brian Osman <brianosman@google.com>

# This script is written to process the output from bloaty, read via stdin

|
|
#
|
|
# bloaty <path_to_binary> -d compileunits,symbols -n 0 --tsv | bloaty_treemap.py > bloaty.html

# TODO: Deal with symbols vs. fullsymbols, even both?
|
|
# TODO: Support aggregation by scope, rather than file (split C++ identifiers on '::')
|
|
# TODO: Deal with duplicate symbols better. These are actually good targets for optimization.
|
|
# They are sometimes static functions in headers (so they appear in multiple .o files),
|
|
# There are also symbols that appear multiple times due to inlining (eg, kNoCropRect).
|
|
# TODO: Figure out why some symbols are misattributed. Eg, Swizzle::Convert and ::Make are tied
|
|
# to the header by nm, and then to one caller (at random) by bloaty. They're not inlined,
|
|
# though. Unless LTO is doing something wacky here? Scope-aggregation may be the answer?
|
|
# Ultimately, this seems like an issue with bloaty and/or debug information itself.
