Replace adhoc inline implementation of llvm::array_lengthof in favour of the
implementation in LLVM. This is simply a cleanup change, no functional change
intended.
llvm-svn: 211868
Rationale:
Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as
std::__1::vector<int, std::__1::allocator<....
rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code
Proposed solution:
Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name
Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point
LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem
Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice
The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one
It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type
Caveats:
- for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet.
- while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters

This decision has always been statically-bound to the individual formatter. With this patch, the idea is that this decision could potentially be dynamic depending on the ValueObject itself
llvm-svn: 207046
Enable data formatters to see-through pointers/references to typedefs
For instance, if Foo is a typedef to Bar, and there is a formatter for any/all of Bar*, Bar&, Bar&&, then Foo*, Foo&, and Foo&& should pick these up if Foo-specific formatters don't exist

This is a purely mechanical change explicitly casting any parameters for printf
style conversion. This cleans up the warnings emitted by gcc 4.8 on Linux.

This is a mechanical cleanup of unused functions. In the case where the
functions are referenced (in comment form), I've simply commented out the
functions. A second pass to clean that up is warranted.
The functions which are otherwise unused have been removed. Some of these were
introduced in the initial commit and not in use prior to that point!

Provide a filter for libc++ std::atomic<T>
This just hides some implementation clutter and promotes the actual content to only child status
llvm-svn: 200984
The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)
The SB API has also been improved to handle both types of formats, and a test case is added

So, rename the class for what it truly is: a FormattersContainer
Also do a bunch of related text substitutions in the interest of overall naming clarity

Rework data formatters matching algorithm
What happens now is that, for each category, the FormatNavigator generates all possible matches, and checks them one by one
Since the possible matches do not actually depend on the category (whether a match is accepted or not does, but that check can be shifted at a more convenient time),
it is actually feasible to generate every possible match upfront and then let individual categories just scan through those
This commit changes things by introducing a notion of formatters match candidate, and shifting responsibility for generating all of them given a (ValueObject,DynamicValueType) pair
from the FormatNavigator back to the FormatManager
A list of these candidates is then passed down to each category for matching
Candidates also need to remember whether they were generated by stripping pointers, references, typedefs, since this is something that individual formatters can choose to reject
This check, however, is conveniently only done once a "textual" match has been found, so that the list of candidates is truly category-independent
While the performance benefit is small (mostly, due to caching), this is much cleaner from a design perspective
llvm-svn: 195395
User-vended by-type formatters still would prevail on these hardcoded ones
For the time being, while the infrastructure is there, no such formatters exist
This can be useful for cases such as expanding vtables for C++ class pointers, when there is no clear cut notion of a typename matching, and the feature is low-level enough that it makes sense for the debugger core to be vending it
llvm-svn: 193724
Introduce a new boolean setting enable-auto-oneliner
This setting if set to false will force LLDB to not use the new compact one-line display
By default, one-line mode stays on, at least until we can be confident it works.
But now if it seriously impedes your workflow while it evolves/it works wonders but you still hate it, there's a way to turn it off
llvm-svn: 193450
This check was overly strict. Relax it.
While one could conceivably want nested one-lining:
(Foo) aFoo = (x = 1, y = (t = 3, q = “Hello), z = 3.14)
the spirit of this feature is mostly to make *SMALL LINEAR* structs come out more compact.
Aggregates with children and no summary for now just disable the one-lining. Define a one-liner summary to override :)
