In one case, some headers were included solely for the purpose of declaring a nested class in Target, which was not needed by anybody outside the class.

* Fixed more fallout from running the test suite remotely on iOS devices.Greg Clayton2014-11-171-4/+27
| | | | | | | | | | | | | | | | Fixed include: - Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch). - Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. - Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now - Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules: size_t Target::UnloadModuleSections (const ModuleList &module_list); size_t Target::UnloadModuleSections (const lldb::ModuleSP &module_sp); llvm-svn: 222167
* Fixed SBTarget::ReadMemory() to work correctly and the TestTargetAPI.py test ↵Greg Clayton2014-11-041-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | case that was reading target memory in TargetAPITestCase.test_read_memory_with_dsym and TargetAPITestCase.test_read_memory_with_dwarf. The problem was that SBTarget::ReadMemory() was making a new section offset lldb_private::Address by doing: size_t SBTarget::ReadMemory (const SBAddress addr, void *buf, size_t size, lldb::SBError &error) { ... lldb_private::Address addr_priv(addr.GetFileAddress(), NULL); bytes_read = target_sp->ReadMemory(addr_priv, false, buf, size, err_priv); This is wrong. If you get the file addresss from the "addr" argument and try to read memory using that, it will think the file address is a load address and it will try to resolve it accordingly. This will work fine if your executable is loaded at the same address (no slide), but it won't work if there is a slide. The fix is to just pass along the "addr.ref()" instead of making a new addr_priv as this will pass along the lldb_private::Address that is inside the SBAddress (which is what we want), and not always change it into something that becomes a load address (if we are running), or abmigious file address (think address zero when you have 150 shared libraries that have sections that start at zero, which one would you pick). The main reason for passing a section offset address to SBTarget::ReadMemory() is so you _can_ read from the actual section + offset that is specified in the SBAddress. llvm-svn: 221213

* Make the "synchronous" mode actually work without race conditions.Greg Clayton2014-10-211-4/+4
| | | | | | There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file. llvm-svn: 201003

The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform. The API in SBPlatform is subject to change and will be getting many new functions. llvm-svn: 195273

StackFrame is currently the only subclass and the methods that Frame vends are nearly identical to StackFrame's old methods. Update all callers to use Frame*/Frame& instead of pointers to StackFrames. This is almost entirely a mechanical change that touches a lot of the code base so I'm committing it alone. No new functionality is added with this patch, no new subclasses of Frame exist yet. I'll probably need to tweak some of the separation, possibly moving some of StackFrame's methods up in to Frame, but this is a good starting point. <rdar://problem/15314068> llvm-svn: 193907

| | | | | | | | | | | | This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain) With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection llvm-svn: 193564

So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging. Linux and FreeBSD should quickly enable this feature if possible, or return an error for any breakpoints that are hardware breakpoint sites in the "virtual Error Process::EnableBreakpointSite (BreakpointSite *bp_site);" function. llvm-svn: 192491

* Huge change to clean up types.Greg Clayton2013-07-111-3/+3
| | | | | | | | A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130
* Added a way to extract the module specifications from a file. A module ↵Greg Clayton2013-07-081-0/+11
| | | | | | | | | | | | | specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files). There are two new classes: lldb::SBModuleSpec lldb::SBModuleSpecList The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList. llvm-svn: 185877

| | | | | | | | | | PC relative loads are missing disassembly comments when disassembled in a live process. This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually. The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases. llvm-svn: 178315
