Filipe was attempting to do a:
(lldb) process load ~/path/foo.dylib
But the process load command wasn't resolving the path. We have to be careful
about resolving the path here because we want to do it in terms of the platform
we are using. the "~/" can mean a completely different path if you are remotely
debugging on another machine as another user. So to support this, platforms now
can resolve remote paths:
bool
Platform::ResolveRemotePath (const FileSpec &platform_path,
FileSpec &resolved_platform_path);
The host/local platform will just resolve the path.

This is helping us track down some extra references to ModuleSP objects that
are causing things to get kept around for too long.
Added a module pointer accessor to target and change a lot of code to use
it where it would be more efficient.
"taret delete" can now specify "--clean=1" which will cleanup the global module
list for any orphaned module in the shared module cache which can save memory
and also help track down module reference leaks like we have now.

10 second timeout zone. When launching we increase the
timeout to 10 seconds to ensure we have time to launch a
process, and then set it back.

of string literals ("hello"[2]). Also fixed a
problem in which empty string literals were not
being compiled correctly ((int)printf("") would
print garbage).
Added a testcase that covers both.
llvm-svn: 137247
ability to dump more information about modules in "target modules list". We
can now dump the shared pointer reference count for modules, the pointer to
the module itself (in case performance tools can help track down who has
references to said pointer), and the modification time.
Added "target delete [target-idx ...]" to be able to delete targets when they
are no longer needed. This will help track down memory usage issues and help
to resolve when module ref counts keep getting incremented. If the command gets
no arguments, the currently selected target will be deleted. If any arguments
are given, they must all be valid target indexes (use the "target list"
command to get the current target indexes).
Took care of a bunch of "no newline at end of file" warnings.
TimeValue objects can now dump their time to a lldb_private::Stream object.
Modified the "target modules list --global" command to not error out if there
are no targets since it doesn't require a target.
Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared
library was updated on disk, we would keep using the older one, even if it was
updated.
Don't allow the ModuleList::GetSharedModule(...) to return an empty module.
Previously we could specify a valid path on disc to a module, and specify an
architecture that wasn't contained in that module and get a shared pointer to
a module that wouldn't be able to return an object file or a symbol file. We
now make sure an object file can be extracted prior to adding the shared pointer
to the module to get added to the shared list.

new --raw-output (-R) option to frame variable prevents using summaries and synthetic children
other future formatting enhancements will be excluded by using the -R option
test case enhanced to check that -R works correctly

library has already been unloaded by the time we get to it.

event is removed. Also use the return value of asynchronous breakpoint callbacks, they get checked before, and override the
breakpoint conditions.
Added ProcessModInfo class, to unify "stop_id generation" and "memory modification generation", and use where needed.

if your datatype provides synthetic children, "frame variable object[index]" should now do the right thing
in cases where the above syntax would have been rejected before, i.e.
object is not a pointer nor an array (frame variable ignores potential overload of [])
object is a pointer to an Objective-C class (which cannot be dereferenced)
expression will still run operator[] if available and complain if it cannot do so
synthetic children by name do not work yet
llvm-svn: 137097
command that allows us to see all modules that exist and
their corresponding global shared pointer count. This will
help us track down memory issues when modules aren't being
removed and cleaned up from the module list.

that detects what context the current expression is
meant to execute in. LLDB now properly consults
the method declaration in the debug information
rather than trying to hunt down the "this" or "self"
pointer by name, which can be misleading.
Other fixes include:
- LLDB now properly detects that it is inside
an inlined C++ member function.
- LLDB now allows access to non-const members when
in const code.
- The functions in SymbolFile that locate the
DeclContext containing a DIE have been renamed
to reflect what they actually do. I have added
new functions that find the DeclContext for the
DIE itself.
I have also introduced testcases for C++ and
Objective-C.

a native architecture that doesn't match the universal
slice that is being used for all executables, we weren't
correctly descending through the platform architectures
and resolving the binaries.
llvm-svn: 136980
expressions that used function pointers. The problem
was that IRForTarget previously only scanned the IR
for the expression for call instructions; if a function
was used in another context, it was ignored.
Now LLDB scans the Module for functions that are only
declared (not also defined -- so these are externals);
it then constructs function pointers for these
functions and substitutes them wherever the function
is used.
Also made some changes so that "expr main" works just
as well as "expr &main"; they end up being the same
code, but LLDB was generating the result variable in
different ways.

- accordingly, the test cases for the synthetic providers for the std:: containers have been edited to use
${svar%#} instead of ${svar.len} to print out the count of elements ; the .len synthetic child has been
removed from the synthetic providers
The synthetic children providers for the std:: containers now return None when asked for children indexes >= num_children()
Basic code to support filter names based on regular expressions (WIP)
llvm-svn: 136862
The synthetic children providers now use the new (safer) APIs to get the values of objects
As a side effect, fixed an issue in ValueObject where ResolveValue() was not always updating the value before reading it
llvm-svn: 136861
the SBType implementation classes.
Fixed LLDB core and the test suite to not use deprecated SBValue APIs.
Added a few new APIs to SBValue:
int64_t
SBValue::GetValueAsSigned(int64_t fail_value=0);
uint64_t
SBValue::GetValueAsUnsigned(uint64_t fail_value=0)
llvm-svn: 136829
current context. Previously, if there was a variable
called "self" available, the expression parser
assumed it was inside a method. But class methods
in Objective-C also take a "self" parameter, of DWARF
type "id". We now detect this properly, and only
assume we're in an instance method if "self" is a
pointer to an Objective-C object.

The entire .a file gets cached, and after the first .o file
gets loaded, a cached version would get used when trying to
extract the skinny slice from a fat BSD archive and would
cause a code path to get taken in the BSD archive parser
even if we aren't at a BSD archive offset.

- see the test case in lang/objc/objc-dynamic-value for an example
Objective-C dynamic type lookup now works for every Objective-C type
- previously, true dynamic lookup was only performed for type id
