This patch modifies the Get/Set Register Value/Context functions for Intel to not duplicate code for reading non-AVX registers. This is similar to other transformations I've been making to the AVX register handling code.
llvm-svn: 297787
This patch consolidates the DEBUG_FPU_REGS code for i386 and x86_64 to take advantage of the fact that the non-AVX members of the avx register state structure overlap with the standard fpu register state structure.
This reduces the amount of code required to set debug values into the register state structures because the register state structures are stored in a union.

Summary:
The first Sandybridge iMacs with AVX support shipped in Spring 2011 with Snow Leopard as their OS. Unfortunately due to a kernel bug debugging AVX code was not really possible until 10.7.4.
The old code here checked the kernel build number to determine when to support AVX, but that code was incorrect. It verified that the kernel build number was greater than xnu-2020, which is the build of the kernel that had the fix for 10.8. The fix was also back ported to 10.7.4. Which means all publicly available OS builds 10.7.4 and later have working AVX support.
This new patch verifies that the host OS is greater than or equal to 10.7.4 by checking that the build number is greater than or equal to 11Exx.
The patch also removes the HasAVX assembly blob in favor of querying the kernel via sysctl for the hardware features.
Using sysctl is slower, however since the code is executed once and the result cached it is a better approach because it is possible for the kernel to disable AVX support on hardware that supports it, so listening to the kernel is a better approach for the debugger to take.

Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.
This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

requires that this private framework be available - and it is not
available earlier than macOS 10.12 - to build lldb), dlopen the
framework binary on demand in debugserver. We're already using
dlsym() to look up all the symbols so there is no need to use weak
linking here.

30 seconds to match the old springboard timeout; the launcher
should time out before that and we will hopefully get back
an informative error message instead of timing out ourselves.

In LLVM's CMake we have a convention that components have both a build and an install target. Making LLDB follow this convention will allow LLDB to take advantage of the LLVM_DISTRIBUTION_COMPONENTS build option from LLVM.
llvm-svn: 289879
Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.
With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.
The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.
With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Ubuntu 14.04 with clang-3.6.
