[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default (2)

Authored by hyeongyukim on Aug 20 2021, 2:50 AM.



This patch updates test files after D105169.
Autogenerated test codes are changed by utils/, and non-autogenerated test codes are changed as follows:

(1) I wrote a python script that (partially) updates the tests using regex:

The script is not perfect, but I believe it gives hints about which patterns are updated to have noundef attached.

(2) The remaining tests are updated manually.

This and D105169 are renewed version of the old patch (D82317).
When pushing to the main branch, I'll commit this and D105169 as a single commit to avoid CI failure.

aqjune retitled this revision from [Clang/Test]: Enable enable_noundef_analysis as default(2) to [Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default (2).Aug 22 2021, 11:23 PM

Hello all, I'm a messenger of @hyeongyukim's two patches that allow clang to turn on noundef analysis by default.
The motivation and background of these patches are described at

Here is a list of tests that has RUN: %clang_cc1 replaced with RUN: %clang_cc1 -disable-noundef-analysis:

They are updated to simply have the -disable-noundef-analysis because of the complicatedness of fixing them.

As described in, a major concern with turning on this flag is that it requires a lot of tests to be updated, possibly raising conflicts with downstreams.
To avoid this, I'd like to receive requests for tests that need -disable-noundef-analysis. If the directories or tests are specified, I'll simply add the flag to the RUN: command.
This will reduce the opportunity of raising conflicts with downstreams.
