* [NativeProcessLinux] Integrate MainLoopPavel Labath2015-07-211-40/+8
| | | | | | | | | | | | | | | | | | | Summary: This commit integrates MainLoop into NativeProcessLinux. By registering a SIGCHLD handler with the llgs main loop, we can get rid of the special monitor thread in NPL, which saves as a lot of thread ping-pong when responding to client requests (e.g. qThreadInfo processing time has been reduced by about 40%). It also makes the code simpler, IMHO. Reviewers: ovyalov, clayborg, tberghammer, chaoren Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D11150 This is a resubmission of r242305 after it was reverted due to bad interactions with the stdio thread. llvm-svn: 242783

* [NativeProcessLinux] Refactor PtraceWrapperPavel Labath2015-06-301-13/+5
| | | | | | | | | | | | | | | | | Summary: This changes PtraceWrapper to return an Error, while the actual result is in an pointer parameter (instead of the other way around). Also made a couple of PtraceWrapper arguments default to zero. This arrangement makes a lot of the code much simpler. Test Plan: Tests pass on linux. It compiles on android arm64/mips64.

* [NativeProcessLinux] Use lambdas in DoOperation callsPavel Labath2015-06-261-149/+71
| | | | | | | | | | | | | | | | | | | Summary: This removes a lot of boilerplate, which was needed to execute monitor operations. Previously one needed do declare a separate class for each operation which would manually capture all needed arguments, which was very verbose. In addition to less code, I believe this also makes the code more readable, since now the implementation of the operation can be physically closer to the code that invokes it. Test Plan: Code compiles on x86, arm and mips, tests pass on x86 linux.

* Move register reading form NativeProcessLinux to NativeRegisterContextLinux*Tamas Berghammer2015-05-261-68/+107
| | | | | | | | | | | | | | | | | This change reorganize the register read/write code inside lldb-server on Linux with moving the architecture independent code into a new class called NativeRegisterContextLinux and all of the architecture dependent code into the appropriate NativeRegisterContextLinux_* class. As part of it the compilation of the architecture specific register contexts are only compiled on the specific architecture because they can't be used in other cases. The purpose of this change is to remove a lot of duplicated code from the different register contexts and to remove the architecture dependent codes from the global NativeProcessLinux class.
