As a preliminary to making DIL the default implementation for
'frame var', ran check-lldb forcing 'frame var' to always use DIL,
and discovered a few failing tests. This fixes most of them. The only
remaining failing test is TestDAP_evaluate.py, which now passes
a test case that the test says should fail (still investigating this).
Changes in this PR:
- Sets correct VariableSP, as well as returning ValueObjectSP (needed
for several watchpoint tests).
- Updates error messages, when looking up members, to match what the
rest of LLDB expects. Also update appropriate DIL tests to expect the
updated error messages.
- Updates DIL parser to look for and accept "(anonymous namespace)::" at
the front of a variable name.
This fixes 3 warnings from compiling the DILParser:
DILParser.h:53:12: warning: returning address of local temporary object
[-Wreturn-stack-address]
DILParser.h:119:8: warning: private field 'm_fragile_ivar' is not used
[-Wunused-private-field]
DILParser.h:120:8: warning: private field 'm_check_ptr_vs_member' is not
used [-Wunused-private-field]
Add the Data Inspection Language (DIL) implementation pieces for
handling plain local and global variable names.
See https://discourse.llvm.org/t/rfc-data-inspection-language/69893 for
information about DIL.
This change includes the basic AST, Lexer, Parser and Evaluator pieces,
as well as some tests.
