Because everything live is spilled at the end of a
block by fast regalloc, assume this will happen and
avoid the copies of the resource descriptor.

These instructions were only defined for microMIPSR6 previously. Add
definitions for MIPSR6, correct definitions for microMIPSR6, flag these
instructions as having unmodelled side effects (they disable/enable
virtual processors) and add missing disassember tests for microMIPSR6.

Summary:
ObjectFileELF::RefineModuleDetailsFromNote() identifies Linux core dumps by searching for
library paths starting with /lib/x86_64-linux-gnu or /lib/i386-linux-gnu. This change widens the
test to allow for linux installations which have addition directories in the path.

AST matchers are useful for the analyzer's checkers.
More patches on particular checkers shall follow.
This is the first time clang binary gets linked to ASTMatchers.
The binary size increase for the clang executable would be
+0.5% in release mode, +2% in debug mode.

* When moving an outermost enclosing class, all its nested classes should also
be moved together.
* Add a test for not moving nested class.

OpenMP creates a variable array type with a a null size-expr. The Debug
generation failed to due to this. This patch corrects the openmp
implementation, updates the tests, and adds a new one for this
condition.

The Register Calling Convention (RegCall) was introduced by Intel to optimize parameter transfer on function call.
This calling convention ensures that as many values as possible are passed or returned in registers.
This commit presents the basic additions to LLVM CodeGen in order to support RegCall in X86.

We don't need to check if AVX is enabled. It's implied by the operation action being set to Custom.
We don't need to check both the input and output type widths. We only need to check the type that's being inserted or extracted. The other type is known to be a legal type and we can assume its a different width.

Summary:
If Python is installed to a location that contains spaces
(e.g. "C:\Program Files\Python3") then the build fails while attempting
to run the modify-python-lldb.py script because the path to the Python
executable is not double-quoted before being passed to the shell. The
fix consists of letting Python handle the formatting of the command
line, since subprocess.Popen() is perfectly capable of handling paths
containing spaces if it's given the command and arguments as a list
instead of a single pre-formatted string.

This allows RegBankSelect in greedy mode to get rid some of the cross

- Use storage class C_STAT for 'PrivateLinkage' The storage class for
PrivateLinkage should equal to the Internal Linkage.
- Set 'PrivateGlobalPrefix' from "L" to ".L" for MM_WinCOFF (includes
x86_64) MM_WinCOFF has empty GlobalPrefix '\0' so PrivateGlobalPrefix
"L" may conflict to the normal symbol name starting with 'L'.
Based on a patch by Han Sangjin! Manually updated test cases.

still crashes.

On macOS (but not iOS), if an ObjC property has no setter, the nib-loading code
for an IBOutlet is documented as directly setting the backing ivar without
retaining the value -- even if the property is 'retain'.
This resulted in false positives from the DeallocChecker for code that did not
release such ivars in -dealloc.
To avoid these false positives, treat IBOutlet ivars that back a property
without a setter as having an unknown release requirement in macOS.

This document describes the proposal to move to GitHub, and
compare the two proposals through various workflow examples,
presenting the current set of commands following by the ones
involved in each of the two proposals.
It is intended to supersede the previous "submodule proposal"
document entirely, and drive the discussion at the BoF during
the next Dev Meeting.
