11 years agoUse the same SourceManager for ModuleMaps and compilations.
Manuel Klimek [Thu, 24 Oct 2013 07:51:24 +0000 (07:51 +0000)]
Use the same SourceManager for ModuleMaps and compilations.

This allows using virtual file mappings on the original SourceManager to
map in virtual module.map files. Without this patch, the ModuleMap
search will find a module.map file (as the FileEntry exists in the
FileManager), but will be unable to get the content from the
SourceManager (as ModuleMap previously created its own SourceManager).

Two problems needed to be fixed which this patch exposed:

1. Storing the inferred module map
When writing out a module, the ASTWriter stores the names of the files
in the main source manager; when loading the AST again, the ASTReader
errs out if such a file is found missing, unless it is overridden.
Previously CompilerInstance's compileModule method would store the
inferred module map to a temporary file; the problem with this approach
is that now that the module map is handled by the main source manager,
the ASTWriter stores the name of the temporary module map as source to
the compilation; later, when the module is loaded, the temporary file
has already been deleted, which leads to a compilation error. This patch
changes the inferred module map to instead inject a virtual file into
the source manager. This both saves some disk IO, and works with how the
ASTWriter/ASTReader handle overridden source files.

2. Changing test input in test/Modules/Inputs/*
Now that the module map file is handled by the main source manager, the
VerifyDiagnosticConsumer will not ignore diagnostics created while
parsing the module map file. The module test test/Modules/renamed.m uses
-I test/Modules/Inputs and triggers recursive loading of all module maps
in test/Modules/Inputs, some of which had conflicting names, thus
leading errors while parsing the module maps. Those diagnostics already
occur on trunk, but before this patch they would not break the test, as
they were ignored by the VerifyDiagnosticConsumer. This patch thus
changes the module maps that have been recently introduced which broke
the invariant of compatible modules maps in test/Modules/Inputs.

Some background: Both Doug and Richard had asked me in Chicago to remove the circular reference in CXXRecordDecl to LambdaExpr by factoring out and storing the needed information from LambdaExpr directly into CXXRecordDecl.

In addition, I have added an IsGenericLambda flag - this makes life a little easier when we implement capturing, and are Sema-analyzing the body of a lambda (and the calloperator hasn't been wired to the closure class yet). Any inner lambdas can have potential captures that could require walking up the scope chain and checking if any generic lambdas are capture-ready. This 'bit' makes some of that checking easier.

No change in functionality.

The original TransformLambdaExpr (pre generic-lambdas) transformed the TypeSourceInfo of the Call operator in its own instantiation scope via TransformType.  This resulted in the parameters of the call operator being mapped to their transformed counterparts in an instantiation scope that would get popped off.
Then a call to TransformFunctionParameters would add the parameters and their transformed mappings (but newly created ones!) to the current instantiation scope. This would result in a disconnect between the new call operator's TSI parameters and those used to construct the call operator declaration. This was ok in the non-generic lambda world - but would cause issues with nested transformations (when non-generic and generics were interleaved) in the generic lambda world - that I somewhat kludged around initially - but this resulted in PR17476.

The new approach seems cleaner. We only do the transformation of the TypeSourceInfo - but we make sure to do it in the current instantiation scope so we don't lose the untransformed to transformed mappings of the ParmVarDecls when they get created.

Another attempt caused a test to fail (http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20131021/091533.html) and also had to be reverted - my apologies - in my haste, i did not run all the tests - argh!

Now all the tests seem to pass - but a Fixme has been added - since I suspect Richard will find the fix a little inelegant ;) I shall try and work on a more elegant fix once I have had a chance to discuss with Richard or Doug at a later date.

Hopefully the third time;s a charm *fingers crossed*

This does not yet include capturing.

Please see test file for examples.
