2f2feebf - Revert Autogenerate the shebang lines for tools/opt-viewer

Tue, 27 Aug 2019 18:31:29 +0000

Revert Autogenerate the shebang lines for tools/opt-viewerThis reverts r369486 (git commit 8d18384809957cc923752e10a86adab129e3df48)The opt-viewer tests don't pass after this change, and fixing them isn'ttrivial. opt-viewer.py imports optmap, which requires adjustingpythonpath, which is more work than I'm willing to do to fix forward.llvm-svn: 370095 List of files: /llvm-project-15.0.7/llvm/tools/opt-viewer/opt-diff.py

817e90f1 - [opt-viewer] Reduce memory consumption by another 20-25%

Wed, 19 Jul 2017 22:04:59 +0000

[opt-viewer] Reduce memory consumption by another 20-25%The Args field of the remark which consists of a list of mappings in YAML istranslated into a list of (small) dicts on Python. An empty dict is 280 byteson my system so we can save memory by using a tuple of tuples instead.Making a tuple of tuples rather than a list of tuples allows Args to be sharedwith the key of the remark. This is actually an even greater saving. (Keysare alive throughout the entire run in all_remarks.)Here are a few opt-stats runs with different input sizes while measuring heapusage with heapy. Avg remark size is simply estimated asheap-size / # of remarks: | # of files | 60 | 114 | 308 | 605 | 1370 | | # of remarks | 20K | 37K | 146K | 180K | 640K | | total file size (MB) | 22 | 51 | 219 | 202 | 1034 | |------------------------+------+------+------+------+------| | Avg remark size before | 4339 | 4792 | 4761 | 4096 | 4607 | | Avg remark size after | 3446 | 3641 | 3567 | 3146 | 3347 | | Rate | 0.79 | 0.76 | 0.75 | 0.77 | 0.73 |Differential Revision: https://reviews.llvm.org/D35611llvm-svn: 308538 List of files: /llvm-project-15.0.7/llvm/tools/opt-viewer/opt-diff.py

659d7dbb - [opt-viewer] Accept directories that are searched for opt.yaml files

8d10129e - [opt-viewer] Move under tools, install it

Thu, 06 Jul 2017 17:51:15 +0000

[opt-viewer] Move under tools, install itWe weren't installing opt-viewer and co before, this fixes the omission. I amalso moving the tools from utils/ to tools/. I believe that this is moreappropriate since these tools have matured greatly in the past year throughcontributions by multiple people (thanks!) so they are ready to becomeexternal tools.The tools are installed under /share/opt-viewer/.I am *not* adding the llvm- prefix. If people feel strongly about addingthat, this is probably a good time since the new location will require somemental adjustment anyway.Fixes PR33521Differential Revision: https://reviews.llvm.org/D35048llvm-svn: 307285 List of files: /llvm-project-15.0.7/llvm/tools/opt-viewer/opt-diff.py
