7b63453e9a [cmake] Declare LLVM_CMAKE_PATH for use in subprojects
Declare the LLVM_CMAKE_PATH to the source directory location of CMake
files, in order to make it possible to easily use them in subprojects.
Such a variable is already declared in most of LLVM projects
(and inconsistently mixed with direct source tree references), including
Clang, LLDB, compiler-rt, libcxx... Declaring it inside main LLVM tree
makes it possible to avoid having to declare fallback values or use
conditionals in those projects.

It should be noted that in some of the subprojects LLVM_CMAKE_PATH is
used to reference generated LLVMConfig.cmake file. However, these
references are conditional to stand-alone builds and explicitly
including this file is unnecessary in combined builds.

ab4e0362c7 [Thumb-1] Synthesize TBB/TBH instructions to make use of compressed jump tables
The TBB and TBH instructions in Thumb-2 allow jump tables to be compressed into sequences of bytes or shorts respectively. These instructions do not exist in Thumb-1, however it is possible to synthesize them out of a sequence of other instructions.

It turns out this sequence is so short that it's almost never a lose for performance and is ALWAYS a significant win for code size.

TBB example:
Before: lsls r0, r0, #2    After: add  r0, pc
        adr  r1, .LJTI0_0         ldrb r0, [r0, #6]
        ldr  r0, [r0, r1]         lsls r0, r0, #1
        mov  pc, r0               add  pc, r0
  => No change in prologue code size or dynamic instruction count. Jump table shrunk by a factor of 4.

The only case that can increase dynamic instruction count is the TBH case:

Before: lsls r0, r4, #2    After: lsls r4, r4, #1
        adr  r1, .LJTI0_0         add  r4, pc
        ldr  r0, [r0, r1]         ldrh r4, [r4, #6]
        mov  pc, r0               lsls r4, r4, #1
                                  add  pc, r4
  => 1 more instruction in prologue. Jump table shrunk by a factor of 2.

So there is an argument that this should be disabled when optimizing for performance (and a TBH needs to be generated). I'm not so sure about that in practice, because on small cores with Thumb-1 performance is often tied to code size. But I'm willing to turn it off when optimizing for performance if people want (also note that TBHs are fairly rare in practice!)

cdb220aad5 [AVX-512] Teach isel lowering that a subvector broadcast being inserted into both halves of a 512-bit vector can be combined into a larger subvector broadcast.
Summary:
This allows us to create broadcasts of 128-bit vector loads into 512-bit vectors.

New patterns added to support 8-bit and 16-bit vector types and v2f64/v2i64->v8f64/v8i64 without DQI instructions.

There also fallback patterns when the load can't be folded. These patterns are a little complex as we first need to insert the lower 128-bits into the second 128-bits using a zmm subvector insert instruction. We need to use a zmm insert in case VLX isn't available. Then use another zmm sub vector insert to take those 256-bits and insert them into the upper bits. Since we used a zmm insert to create the 256-bits we also need to do a extract_subreg to get just the lower 256-bits to pass to the second insert.

The outer insert for the fallback patterns should have its type correct because eventually we should also supported masked operations here too. So we need a DQI and a NoDQI version of the v16f32/v16i32 patterns.

f2a459b587 Using branch probability to guide critical edge splitting.
Summary:
The original heuristic to break critical edge during machine sink is relatively conservertive: when there is only one instruction sinkable to the critical edge, it is likely that the machine sink pass will not break the critical edge. This leads to many speculative instructions executed at runtime. However, with profile info, we could model the splitting benefits: if the critical edge has 50% taken rate, it would always be beneficial to split the critical edge to avoid the speculated runtime instructions. This patch uses profile to guide critical edge splitting in machine sink pass.

fe89a6bcf0 Conditionally eliminate library calls where the result value is not used
Summary:
This pass shrink-wraps a condition to some library calls where the call
result is not used. For example:
   sqrt(val);
 is transformed to
   if (val < 0)
     sqrt(val);
Even if the result of library call is not being used, the compiler cannot
safely delete the call because the function can set errno on error
conditions.
Note in many functions, the error condition solely depends on the incoming
parameter. In this optimization, we can generate the condition can lead to
the errno to shrink-wrap the call. Since the chances of hitting the error
condition is low, the runtime call is effectively eliminated.

These partially dead calls are usually results of C++ abstraction penalty
exposed by inlining. This optimization hits 108 times in 19 C/C++ programs
in SPEC2006.

d9b0063780 [AArch64] Avoid materializing 0.0 when generating FP SELECT
Transform `a == 0.0 ? 0.0 : x` to `a == 0.0 ? a : x` and `a != 0.0 ? x : 0.0`
to `a != 0.0 ? x : a` to avoid materializing 0.0 for FCSEL, since it does not
have to be materialized beforehand for FCMP, as it has a form that has 0.0
as an implicit operand.

c6b8aca5b5 One more additional error check for invalid Mach-O files for a
load command that use the MachO:: linkedit_data_command
type but is not used in llvm libObject code but used in llvm tool code.

This is for the LC_CODE_SIGNATURE load command.

10519cde2d GlobalISel: select small binary operations on AArch64.
AArch64 actually supports many 8-bit operations under the definition used by
GlobalISel: the designated information-carrying bits of a GPR32 get the right
value if you just use the normal 32-bit instruction.
