These tools could be used for automated size analysis.(E.g. in CI).To specify JSON output, use `--report_style=json`. JSON output can bepretty-printed via `--pretty`.With automation in mind, the schema looks like this:```"Files": { "A": <filename_a> "B": <filename_b>},"InBoth": [ { "FunctionName": <function name>, "InstCount": [ <count_in_a>, <count_in_b> ], "StackSize": [ <count_in_a>, <count_in_b> ] }, ...]"OnlyInA": [ { "FunctionName": <function name>, "InstCount": [ <count_in_a>, 0 ], "StackSize": [ <count_in_a>, 0 ] }, ...]"OnlyInB": [ { "FunctionName": <function name>, "InstCount": [ 0, <count_in_b> ], "StackSize": [ 0, <count_in_b> ] }, ...]```A few notes:- Filenames are included, because tools may want to combine many outputs together in some way (a big JSON file, a big CSV, or something.)- Counts are represented as [a, b] so that a diff can be calculated via b - a. The original counts may be useful for size analysis (e.g. was this function extremely large before?) and so both are preserved.- `OnlyInA` and `OnlyInB` have a 0 for one of the counts always. This is to make it easier for tools to share code between `OnlyInA`, `OnlyInB`, and `InBoth`.Differential Revision: https://reviews.llvm.org/D121173 List of files: /llvm-project-15.0.7/llvm/test/tools/llvm-remark-size-diff/json-no-difference.test Mon, 07 Mar 2022 23:33:12 +0000 Jessica Paquette <jpaquette@apple.com>
