* Introduce chrono to more gdb-remote functionsPavel Labath2016-11-248-105/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This replaces the usage of raw integers with duration classes in the gdb-remote packet management functions. The values are still converted back to integers once they go into the generic Communication class -- that I am leaving to a separate change. The changes are mostly straight-forward (*), the only tricky part was representation of infinite timeouts. Currently, we use UINT32_MAX to denote infinite timeout. This is not well suited for duration classes, as they tend to do arithmetic on the values, and the identity of the MAX value can easily get lost (e.g. microseconds(seconds(UINT32_MAX)).count() != UINT32_MAX). We cannot use zero to represent infinity (as Listener classes do) because we already use it to do non-blocking polling reads. For this reason, I chose to have an explicit value for infinity. The way I achieved that is via llvm::Optional, and I think it reads quite natural. Passing llvm::None as "timeout" means "no timeout", while passing zero means "poll". The only tricky part is this breaks implicit conversions (seconds are implicitly convertible to microseconds, but Optional<seconds> cannot be easily converted into Optional<microseconds>). For this reason I added a special class Timeout, inheriting from Optional, and enabling the necessary conversions one would normally expect. (*) The other tricky part was GDBRemoteCommunication::PopPacketFromQueue, which was needlessly complicated. I've simplified it, but that one is only used in non-stop mode, and so is untested.

* [clang-move] Enable dump all declarations in old header.Haojian Wu2016-11-244-135/+279
| | | | | | | | | | | | | | | | | | | Summary: * Add -dump_dels option to dump all declarations from old header. It will allow clang-move used as a frontend to get declarations from header. Further more, this will make debugging stuff easier. Currently only class/function types are supported. * Refactoring code a little bit by creating a ClangMoveContext which holds all options for ClangMoveTool, which can simplify the code in some degree.

* Patch for lldb bug 26322 “core load hangs”Howard Hellyer2016-11-2415-2/+477
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch changes the way ProcessElfCore.cpp handles signal information. The patch changes ProcessElfCore.cpp to use the signal from si_signo in SIGINFO notes in preference to the value of cursig in PRSTATUS notes. The value from SIGINFO seems to be more thread specific. The value from PRSTATUS is usually the same for all threads even if only one thread received a signal. If it cannot find any SIGINFO blocks it reverts to the old behaviour and uses the value from cursig in PRSTATUS. If after that no thread appears to have been stopped it forces the status of the first thread to be SIGSTOP to prevent lldb hanging waiting for any thread from the core file to change state. The order is: - If one or more threads have a non-zero si_signo in SIGINFO that will be used. - If no threads had a SIGINFO block with a non-zero si_signo set all threads signals to the value in cursig in their PRSTATUS notes. - If no thread has a signal set to a non-zero value set the signal for only the first thread to SIGSTOP. This resolves two issues. The first was identified in bug 26322, the second became apparent while investigating this problem and looking at the signal values reported for each thread via “thread list”. Firstly lldb is able to load core dumps generated by gcore where each thread has a SIGINFO note containing a signal number but cursig in the PRSTATUS block for each thread is 0. Secondly if a SIGINFO note was found the “thread list” command will no longer show the same signal number for all threads. At the moment if a process crashes, for example with SIGILL, all threads will show “stop reason = signal SIGILL”. With this patch only the thread that executed the illegal instruction shows that stop reason. The other threads show “stop reason = signal 0”.

| | | | | | | | | | | | | | Change the IRObjectFile symbol iterator to be a pointer into a vector of PointerUnions representing either IR symbols or asm symbols. This change is in preparation for a future change for supporting multiple modules in an IRObjectFile. Although it causes an increase in memory consumption, we can deal with that issue separately by introducing a bitcode symbol table.

| | | | | | | | | | | | The scavenger was not passed if requiresFrameIndexScavenging was enabled.

* Rely on a single DWARF version instead of having two copiesGreg Clayton2016-11-237-16/+24
| | | | | | | | This patch makes AsmPrinter less reliant on DwarfDebug by relying on the DWARF version in the AsmPrinter's MCStreamer's MCContext. This allows us to remove the redundant DWARF version from DwarfDebug. It also lets us change code that used to access the AsmPrinter's DwarfDebug just to get to the DWARF version by changing the DWARF version accessor on AsmPrinter so that it grabs the version from its MCStreamer's MCContext.

* [ELF][MIPS] Fix handling of _gp/_gp_disp/__gnu_local_gp symbolsSimon Atanasyan2016-11-237-22/+86
| | | | | | | | | | | | | | | | | | | | | | | | Offset between beginning of a .got section and _gp symbols used in MIPS GOT relocations calculations. Usually the expression looks like VA + Offset - GP, where VA is the .got section address, Offset - offset of the GOT entry, GP - offset between .got and _gp. Also there two "magic" symbols _gp_disp and __gnu_local_gp which hold the offset mentioned above. These symbols might be referenced by MIPS relocations. Now the linker always defines _gp symbol and uses hardcoded value for its initialization. So offset between .got and _gp is 0x7ff0. The _gp_disp and __gnu_local_gp defined if required and initialized by 0x7ff0. In fact that is not correct because _gp symbol might be defined by a linker script and holds arbitrary value. In that case we need to use this value in relocation calculation and initialize _gp_disp and __gnu_local_gp properly. The patch fixes the problem and completes fixing the bug #30311. https://llvm.org/bugs/show_bug.cgi?id=30311 Differential revision: https://reviews.llvm.org/D27036 llvm-svn: 287832
