Get debugserver to call task_set_state to prime the control registers so that watchpoints take for threads created while the program is running. Remove the testcase skips from TestConcurrentEvents.py, since they all pass now, and fix TestWatchpointMultipleThreads.py - which should have caught this problem - so it doesn't artificially break on new thread creation before the watchpoint triggers. llvm.org/pr16566 <rdar://problem/14383244> git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@186132 91177308-0d34-0410-b5e6-96231b3b80d8

Remove some unnecessary uses of nub_break_t in the arm specific support files for debugserver to fix a build failure for arm. Also remove some of the code used for software-driven single instruction stepping; this is slowly being yanked out and these particular bits overlap with the nub_break_t going away. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@184828 91177308-0d34-0410-b5e6-96231b3b80d8

Previous check-ins allow to hit the arm hardware watchpoint, with a workaound to handle the issue that the inferior cannot execute past the watchpoint-triggering instruction. The solution is disable the watchpoint before resuming the inferior and make it hardware single step; when the inferior stops again due to single step, re-enable the watchpoint and disable the single step to make the inferior able to continue again without obstacle. rdar://problem/9667960 git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@153273 91177308-0d34-0410-b5e6-96231b3b80d8

WIP snapshot of hardware watchpoints for arm. A simple watchpoint has triggered. However, the debugserver cannot get past the instruction which triggered the watchpoint. So a workaround is in place for the time being which disables the triggered watchpoint before resuming. Lots of commented out printf's remain in the source which needs to be cleaned up.

Many improvements to the Platform base class and subclasses. The base Platform class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@128563 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed Process::Halt() as it was broken for "process halt" after recent changes to the DoHalt down in ProcessGDBRemote. I also moved the functionality that was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has to implement a tricky halt/resume on the internal state thread. The functionality is the same as it was before with two changes: - when we eat the event we now just reuse the event we consume when the private state thread is paused and set the interrupted bool on the event if needed - we also properly update the Process::m_public_state with the state of the event we consume. Prior to this, if you issued a "process halt" it would eat the event, not update the process state, and then produce a new event with the interrupted bit set and send it. Anyone listening to the event would get the stopped event with a process that whose state was set to "running". Fixed debugserver to not have to be spawned with the architecture of the inferior process. This worked fine for launching processes, but when attaching to processes by name or pid without a file in lldb, it would fail. Now debugserver can support multiple architectures for a native debug session on the current host. This currently means i386 and x86_64 are supported in the same binary and a x86_64 debugserver can attach to a i386 executable. This change involved a lot of changes to make sure we dynamically detect the correct registers for the inferior process. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@119680 91177308-0d34-0410-b5e6-96231b3b80d8

Got the ARM version of debugserver up to date. Renamed the "dispatchqaddr" setting that was coming back for stop reply packets to be named "qaddr" so that gdb doesn't thing it is a register number. gdb was checking the first character and assuming "di" was a hex register number because 'd' is a hex digit. It has been shortened so gdb can safely ignore it. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@113475 91177308-0d34-0410-b5e6-96231b3b80d8
