[clang-rename] introduce better symbol finding and add few more tests
ClosedPublic

Details

Summary

This patch introduces:

  • TypeLoc visiting, which helps a lot in renaming types
  • NestedNameSpecifierLoc visiting (through getting them via ASTMatcher at the moment, though, because RecursiveASTVisitor<T>::VisitNestedNameSpecifierLoc isn't implemented), which helps to treat nested names correctly
  • few refactoring changes

add XFAIL to currently unsupported test

omtcyfz updated this revision to Diff 64374.Jul 18 2016, 1:24 PM

Removed two FIXMEs. Seems like types are now handled correctly. +1 test passing.

applied few stylistic fixes

Can anyone please take a look at this?

My current work is based on this patch and I'd be happy to know I'm doing things right :)

Declarations of multiple variables can be confusing. Please split this declaration.

nit: No need for braces around single-line if bodies.

clang-rename/USRFinder.h

We should implement it then ;)

I guess, this test will need // REQUIRES: shell. You can try to commit without it, but watch windows buildbots closely.

Well, I'm really happy with braces everywhere. The codestyle doesn't prohibit it and I think it's more readable than no braces around single statements in logical blocks.

clang-rename/USRFinder.h

Yes, it's in my TODO list. But I suppose it's better to fix clang-rename first and get back to it a bit later.

As we discussed, there will probably be no need in RecursiveASTVisitors at all in the end.

Anyway, the patch is already in the state when nobody wants to review it :D I'd be happy just to land it and to continue with all the other bugs present in the tool.

This test? There's RUN: cat %s > %t.cpp in every single one of them, I'm not sure what's the issue.

  • reduce rate of hardcoding
  • simplify symbol location finding
  • introduce tests with templates, some of them are PASSing

split declarations

omtcyfz updated this revision to Diff 65056.Jul 22 2016, 5:01 AM

oops... actually split declarations

omtcyfz updated this revision to Diff 65060.Jul 22 2016, 5:41 AM

remove redundant #include and using directives

LG. Thanks!

SG. Please change the comment to // FIXME: Implement RecursiveASTVisitor<T>::VisitNestedNameSpecifier instead..

Actually, cat a > b is a way to write cp a b in lit tests without requiring a shell. I looked this up and was going to delete the comment, but I've hit "Hide" instead. Sorry for the noise.

This revision is now accepted and ready to land.Jul 22 2016, 6:03 AM

@alexfh, awww, sorry, I've uploaded wrong diff last time for whatever reason...

Can you review the changes please?

Now it contains many new tests and I managed to cut off unnecessary blocks of code.

omtcyfz updated this revision to Diff 65066.Jul 22 2016, 6:32 AM

@alexfh, or wait... It's fine, I just forgot to add few tests, sorry.
