The accumulator tail recursion transform claims to work for any associative
...
operation, but the way it's implemented requires the operation to also be
commutative. So add a check for commutativity (and tweak the corresponding
comments). This makes no difference in practice since every associative
LLVM instruction is also commutative! Here's an example to show the need
for commutativity: the accum_recursion.ll testcase calculates the factorial
function. Before the transformation the result of a call is
((((1*1)*2)*3)...)*x
while afterwards it is
(((1*x)*(x-1))...*2)*1
which clearly requires both associativity and commutativity of * to be equal
to the original.

Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"
...
builds to "Release". The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts. The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown). This will bring them
in line with MacOS releases, which ship with assertions disabled. It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.

Implement the "linker_private_weak" linkage type. This will be used for
...
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.
For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:
.globl l_objc_msgSend_fixup_alloc
.weak_definition l_objc_msgSend_fixup_alloc
.section __DATA, __objc_msgrefs, coalesced
.align 3
l_objc_msgSend_fixup_alloc:
.quad _objc_msgSend_fixup
.quad L_OBJC_METH_VAR_NAME_1
This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
Currently only supported on Darwin platforms.

Include the use kind along with the expression in the key of the

use sharing map. The reconcileNewOffset logic already forces a
separate use if the kinds differ, so incorporating the kind in the
key means we can track more sharing opportunities.
More sharing means fewer total uses to track, which means smaller
problem sizes, which means the conservative throttles don't kick
in as often.

When canonicalizing icmp operand order to put the loop invariant
...
operand on the left, the interesting operand is on the right. This
fixes a bug where LSR was failing to recognize ICmpZero uses,
which led it to be unable to reverse the induction variable in the
attached testcase.
Delete test/CodeGen/X86/stack-color-with-reg-2.ll, because its test
is extremely fragile and hard to meaningfully update.

to two calls to the same push_back function, or fold away the two copies of
push_back() in:
struct T { int; };
struct S { char; };
vector<T*> t;
vector<S*> s;
void f(T *x) { t.push_back(x); }
void g(S *x) { s.push_back(x); }
but leave f() and g() separate, since they refer to two different global
variables.
