Historically, we have told contributors that GnuWin32 is a pre-requisite
because our tests depend on utilities such as sed, grep, diff, and more.
However, Git on Windows includes versions of these utilities in its
installation. Furthermore, GnuWin32 has not been updated in many years.
For these reasons, it makes sense to have the ability to run llvm tests
in a way that is both:
a) Easier on the user (less stuff to install)
b) More up-to-date (The verions that ship with git are at least as
new, if not newer, than the versions in GnuWin32.
We add support for this here by attempting to detect where Git is
installed using the Windows registry, confirming the existence of
several common Unix tools, and then adding this location to lit's PATH
environment.

This patch adds support for the lxvp, lxvpx, plxvp, stxvp, stxvpx and pstxvp
instructions in the PowerPC backend. These instructions allow loading and
storing VSX register pairs. This patch also adds the VSRp register class
definition needed for these instructions.

Add the --include-generated-funcs option to update_cc_test_checks.py so that any
functions created by the compiler that don't exist in the source will also be
checked.
We need to maintain the output order of generated function checks so that
CHECK-LABEL works properly. To do so, maintain a list of functions output for
each prefix in the order they are output. Use this list to output checks for
generated functions in the proper order.

When generating matching tables for GlobalISel, TableGen would output
"::zero_reg" whenever encountering the zero_reg, which in turn would
result in compilation error. This patch fixes that by instead outputting
NoRegister (== 0), which is the same result that TableGen produces when
generating matching tables for ISelDAG.

Some compilers generation functions with '$' in their names, so recognize those
functions.
This also requires recognizing function names inside quotes in some contexts in
order to escape certain characters.

If you want to build everything, building the default target
via just `ninja` is better, but `ninja all` shouldn't give you
compile errors -- this fixes that.
Building LLVM with -DEXPENSIVE_CHECKS fails with the following error
message with libstdc++ in debug mode:
Error: comparison doesn't meet irreflexive requirements,
assert(!(a < a)).
The patch fixes the comparison function SizeOrder by returning false
when comparing two equal items.
This patch recommits "[ConstraintSystem] Add helpers to deal with linear constraints."
(it reverts the revert commit 8da6ae4ce1b686c5c13698e4c5ee937811fda6f7).
The reason for the revert was using __builtin_multiply_overflow, which
is not available for all compilers. The patch has been updated to use
MulOverflow from MathExtras.h
As to not conflict with the legacy PM example passes under
llvm/lib/Transforms/Hello, this is under HelloNew. This makes the
CMakeLists.txt and general directory structure less confusing for people
following the example.
Much of the doc structure was taken from WritinAnLLVMPass.rst.
This adds a HelloWorld pass which simply prints out each function name.
More will follow after this, e.g. passes over different units of IR, analyses.
https://llvm.org/docs/WritingAnLLVMPass.html contains a lot more.
Relanded with missing "Support" dependency in LLVMBuild.txt.

The "name" of a non-leaf complex pattern (MY_PAT $op1, $op2) is
"MY_PAT:op1:op2" and the ones with same "name" represent same operand.
Add 'same operand check' for this case.

Predicates with 'let PredicateCodeUsesOperands = 1' want to examine
matched operands. When we encounter predicate code that uses operands,
analyze its named operand arguments and create a map between argument
index and name. Later, when leaf node with name is encountered, emit
GIM_RecordNamedOperand that will store that operand at its argument
index in operand list. This operand list will be an argument to c++
code of the predicate.

Tablegen does not have link time dependencies on MC. Having llvm-tblgen
depend on it causes it to be rebuilt in the gn build every time somebody
touches any cpp file in llvm/lib/MC* or llvm/lib/DebugInfo/Codeview*.
Touching tablegen invalidates most of the rest of the build, and
re-running it takes a while. This is is annoying for me when swapping
between branches that touch CodeView logic.
This dep was added to LLVMBuild.txt back in 2018, and presumably it was
carried over into the gn build.
