Enrico Granata 88da35f881 Improved the user-friendliness of errors shown by the summary feature in certain areas
Renamed format "signed decimal" to be "decimal". "unsigned decimal" remains unchanged:
 - the name "signed decimal" was interfering with symbol %S (use summary) in summary strings.
   because of the way summary strings are implemented, this did not really lead to a bug, but
   simply to performing more steps than necessary to display a summary. this is fixed.
Documentation improvements (more on synthetic children, some information on filters). This is still a WIP.

Sean Callanan bccce81340 Added support for persistent types to the
expression parser.  You can use a persistent
type like this:

(lldb) expr struct $foo { int a; int b; };
(lldb) struct $foo i; i.a = 2; i.b = 3; i
($foo) $0 = {
  (int) a = 2
  (int) b = 3
}

typedefs work similarly.

This patch affects the following files:

test/expression_command/persistent_types/*
  A test case for persistent types,
  in particular structs and typedefs.

ClangForward.h
  Added TypeDecl, needed to declare some
  functions in ASTResultSynthesizer.h

ClangPersistentVariables.[h,cpp]
  Added a list of persistent types to the
  persistent variable store.

ASTResultSynthesizer.[h,cpp]
  Made the AST result synthesizer iterate
  across TypeDecls in the expression, and
  record any persistent types found.  Also
  made a minor documentation fix.

ClangUserExpression.[h,cpp]
  Extended the user expression class to
  keep the state needed to report the
  persistent variable store for the target
  to the AST result synthesizers. 

  Also introduced a new error code for
  expressions that executed normally but
  did not return a result.

CommandObjectExpression.cpp
  Improved output for expressions (like 
  declarations of new persistent types) that
  don't return a result.  This is no longer
  treated as an error.

Sean Callanan 60dbc63a89 Restored the version of LLVM that we previously
rolled back, and the testcase that the rollback
broke.

The new LLVM has a new ARM disassembler, which
may cause instability.  Keeping the old one would
force us into a contorted position vis-a-vis the
LLVM sources we bring in, so we will address
issues on the new one rather than keeping the old
one around.

Enrico Granata 1d887499c4 Code cleanup and refactoring (round 4):
- FormatCategories now are directly mapped by ConstString objects instead of going through
   const char* -> ConstString -> const char*
 - FormatCategory callback does not pass category name anymore. This is not necessary because
   FormatCategory objects themselves hold their name as a member variable

Enrico Granata def5391ae5 - Support for Python namespaces:
If you have a Python module foo, in order to use its contained objects in LLDB you do not need to use
  'from foo import *'. You can use 'import foo', and then refer to items in foo as 'foo.bar', and LLDB
  will know how to resolve bar as a member of foo.
  Accordingly, GNU libstdc++ formatters have been moved from the global namespace to gnu_libstdcpp and a few
  test cases are also updated to reflect the new convention. Python docs suggest using a plain 'import' en lieu of
  'from-import'.

2011-08-22 16:10:25 +00:00
Greg Clayton 56d9a1b31b Added a new plug-in type: lldb_private::OperatingSystem. The operating system
plug-ins are add on plug-ins for the lldb_private::Process class that can add
thread contexts that are read from memory. It is common in kernels to have
a lot of threads that are not currently executing on any cores (JTAG debugging
also follows this sort of thing) and are context switched out whose state is
stored in memory data structures. Clients can now subclass the OperatingSystem
plug-ins and then make sure their Create functions correcltly only enable 
themselves when the right binary/target triple are being debugged. The 
operating system plug-ins get a chance to attach themselves to processes just
after launching or attaching and are given a lldb_private::Process object 
pointer which can be inspected to see if the main executable, target triple,
or any shared  libraries match a case where the OS plug-in should be used.
Currently the OS plug-ins can create new threads, define the register contexts
for these threads (which can all be different if desired), and populate and
manage the thread info (stop reason, registers in the register context) as
the debug session goes on.

2011-08-19 21:56:10 +00:00
Enrico Granata d64d0bc0ea - Now using ${var} as the summary for an aggregate type will produce "name-of-type @ object-location" instead of giving an error
e.g. you may get "foo_class @ 0x123456" when typing "type summary add -f ${var} foo_class"
- Added a new special formatting token %T for summaries. This shows the type of the object.
  Using it, the new "type @ location" summary could be manually generated by writing ${var%T} @ ${var%L}
- Bits and pieces required to support "frame variable array[n-m]"
  The feature is not enabled yet because some additional design and support code is required, but the basics
  are getting there
- Fixed a potential issue where a ValueObjectSyntheticFilter was not holding on to its SyntheticChildrenSP
  Because of the way VOSF are being built now, this has never been an actual issue, but it is still sensible for
  a VOSF to hold on to the SyntheticChildrenSP as well as to its FrontEnd

Johnny Chen 758f288cdd Add a Python script to locate each binary file under a root directory which matches some pathname pattern
and to invoke lldb-disasm.py on the binary file to disassemble its symbols.  The number of symbols can
be specified by, for example, '-n 10000', to specify 10,000 symbols to disassemble for each module.
By default, only 1000 symbols from each module are disassembled.

Example:

utils/test/run-dis.py -r '/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3/Symbols' -p '^/System/Library/.*Frameworks/.*\.framework/[^/]+$'

tries to disassemble every public/private frameworks (by default only 1000 symbols are disassembled) under iOS4.3.

Sean Callanan a87bee84cf Refined the rollback to LLVM, picking up a newer
revision and adding a patch that fixes an AsmParser
crash on ARM.

One feature that we unfortunately lost (for the
moment!) is the ability to cast unknown code symbols
to arbitrary function types and put the resulting
function pointer in a result variable.  This feature
will be back, though.

Enrico Granata 02b6676d2b Third round of code cleanups:
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
 - applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
 - fixed an issue where command type summary add for type "struct Foo" would not match any types.
   currently, "struct" will be stripped off and type "Foo" will be matched.
   similar behavior occurs for class, enum and union specifiers.

Johnny Chen 31963cea0a Add a decorator for marking clang only expectedFailure. Use it for the test_step_over_3_times_with_dsym/dwarf()
test cases in TestThreadAPI.py by decorating it with @expectedFailureClang.

Example:

    @expectedFailureClang
    @python_api_test
    def test_step_over_3_times_with_dwarf(self):
        """Test Python SBThread.StepOver() API."""
        # We build a different executable than the default buildDwarf() does.
        d = {'CXX_SOURCES': 'main2.cpp', 'EXE': self.exe_name}
        self.buildDwarf(dictionary=d)
        self.setTearDownCleanup(dictionary=d)
        self.step_over_3_times(self.exe_name)

Johnny Chen 293683b6c4 Add an option (-p regexp-pattern) to specify the regular expression symbol pattern we're interested in disassembling.
An example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 20 -p '-\[NSArray .+\]'

disassembles the first 20 NSArray instance methods found in the CoreFoundation module.
