This updates the DIL code for handling array subscripting to more
closely match and handle all the cases from the original 'frame var'
implementation. Also updates the DIL array subscripting test. This
particularly fixes some issues with handling synthetic children, objc
pointers, and accessing specific bits within scalar data types.
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 updates the DIL implementation to handle smart pointers (accessing
field members and dereferencing) in the same way the current 'frame
variable' implementation does. It also adds tests for handling smart
pointers, as well as some additional DIL tests.
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.
