Subject: [PATCH] [SystemZ] Use LA instead of AGR in eliminateFrameIndex().
Since AGR clobbers CC it should not be used here.
Fixes https://bugs.llvm.org/show_bug.cgi?id=47736.

[AMDGPU] Avoid an illegal operand in si-shrink-instructions
Before the patch it was possible to trigger a constant bus
violation when folding immediates into a shrunk instruction.
The patch adds a check to enforce the legality of the new operand.

Subject: [PATCH] Enable SSP and PIE by default
This is a minimal set of changes needed to make clang use SSP and PIE by
default on Arch Linux. Tests that were easy to adjust have been changed
accordingly; only test/Driver/linux-ld.c has been marked as "expected
failure" due to the number of changes it would require (mostly replacing
crtbegin.o with crtbeginS.o).
Doing so is needed in order to align clang with the new default GCC
behavior in Arch which generates PIE executables by default and also
defaults to -fstack-protector-strong. It is not meant to be a long term
solution, but a simple temporary fix.
Hopefully these changes will be obsoleted by the introduction upstream
of a compile-time option (https://bugs.llvm.org/show_bug.cgi?id=13410)

From 3d3abc22b3ef189813a3b9061c2a90ba86a32f44 Mon Sep 17 00:00:00 2001
From: serge-sans-paille <sguelton@redhat.com>
Date: Tue, 11 May 2021 20:46:58 +0200
Subject: [PATCH] Force visibility of llvm::Any to external
llvm::Any::TypeId::Id relies on the uniqueness of the address of a static
variable defined in a template function. hidden visibility implies vague linkage
for that variable, which does not guarantee the uniqueness of the address across
a binary and a shared library. This totally breaks the implementation of
llvm::Any.
Ideally, setting visibility to llvm::Any::TypeId::Id should be enough,
unfortunately this doesn't work as expected and we lack time (before 12.0.1
release) to understand why setting the visibility to llvm::Any does work.
See https://gcc.gnu.org/wiki/Visibility and
https://gcc.gnu.org/onlinedocs/gcc/Vague-Linkage.html
for more information on that topic.

Subject: [PATCH 1/3] Fix limit behavior of dynamic alloca
When the allocation size is 0, we shouldn't probe. Within [1, PAGE_SIZE], we
should probe once etc.
This fixes https://bugs.llvm.org/show_bug.cgi?id=47657

Subject: [PATCH 2/3] Fix interaction between stack alignment and inline-asm
stack clash protection
As reported in https://github.com/rust-lang/rust/issues/70143 alignment is not
taken into account when doing the probing. Fix that by adjusting the first probe
if the stack align is small, or by extending the dynamic probing if the
alignment is large.

Subject: [PATCH 3/3] [stack-clash] Fix probing of dynamic alloca
- Perform the probing in the correct direction.
Related to https://github.com/rust-lang/rust/pull/77885#issuecomment-711062924
- The first touch on a dynamic alloca cannot use a mov because it clobbers
existing space. Use a xor 0 instead
Differential Revision: https://reviews.llvm.org/D90216
(cherry picked from commit 0f60bcc36c34522618bd1425a45f8c6006568fb6)

Subject: [PATCH] [Polly] Support linking ScopPassManager against LLVM dylib
Link ScopPassManager to LLVM dylib target if LLVM_LINK_LLVM_DYLIB
is enabled. This fixes build failures on systems where static LLVM
libraries are not installed.
