[cdt-patch] Symbol Table & Complete Parse patch
|
This patch changes the handling of ambiguities during prefix lookup.
It also addresses problems in the symbol table to do with qualified
lookup. Fixing these revealed problems caused by the
CompleteParseASTFactory not always using the correct lookup functions. So
the factory has been modified to call the appropriate lookups.
The following tests have been created:
FailedCompleteParseASTTest.testBug47926
CompleteParseASTTest.testQualifiedLookup
ParserSymbolTableTest.testPrefixLookup_Ambiguities
ParserSymbolTableTest.testQualifiedUnqualifiedLookup
FunctionMethodPatternTests.testLookupForDefinition

+ - Symbol table - modify prefix lookup handling of ambiguities
+ - fix up qualified lookup
+ - add IContainerSymbol.lookupMethodForDefinition
+ - Parser - modify Complete parse AST factory to use the correct lookups in different situations
+ - Created a LookupType enum to specify what kind of lookup is needed (Qualified, unqualified, for definition)
