Andrea Di Biagio 30e94029d8 [MCSchedule] Always generate processor resource names.
With this patch, the tablegen 'SubtargetEmitter' always generates processor
resource names. 
The impact of this patch on the code size of other llvm tools is small.  I have
observed an average increase of 0.03% in code size when doing a release build of
LLVM (on windows, using MSVC) with all the default backends.

This change is done in preparation for the upcoming llvm-mca patch.

Nicolai Haehnle 0409b28af1 TableGen: Use DefInit::getDef() instead of the type's getRecord()
The former simply makes more sense: we want to access the data here in
the backend, not information about the type.

More importantly, removing users of RecordRecTy::getRecord() allows us
more freedom to refactor the frontend.

Geoff Berry f8bf2ec0a8 [MachineOperand][Target] MachineOperand::isRenamable semantics changes
Summary:
Add a target option AllowRegisterRenaming that is used to opt in to
post-register-allocation renaming of registers.  This is set to 0 by
default, which causes the hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq
fields of all opcodes to be set to 1, causing
MachineOperand::isRenamable to always return false.

Set the AllowRegisterRenaming flag to 1 for all in-tree targets that
have lit tests that were effected by enabling COPY forwarding in
MachineCopyPropagation (AArch64, AMDGPU, ARM, Hexagon, Mips, PowerPC,
RISCV, Sparc, SystemZ and X86).

Add some more comments describing the semantics of the
MachineOperand::isRenamable function and how it is set and maintained.

Change isRenamable to check the operand's opcode
hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq bit directly instead of
relying on it being consistently reflected in the IsRenamable bit
setting.

Clear the IsRenamable bit when changing an operand's register value.

Remove target code that was clearing the IsRenamable bit when changing
registers/opcodes now that this is done conservatively by default.

Change setting of hasExtraSrcRegAllocReq in AMDGPU target to be done in
one place covering all opcodes that have constant pipe read limit
restrictions.

Pavel Labath 3b17b84b9c Resubmit r325107 (case folding DJB hash)
The issue was that the has function was generating different results depending
on the signedness of char on the host platform. This commit fixes the issue by
explicitly using an unsigned char type to prevent sign extension and
adds some extra tests.

The original commit message was:

This patch implements a variant of the DJB hash function which folds the
input according to the algorithm in the Dwarf 5 specification (Section
6.1.1.4.5), which in turn references the Unicode Standard (Section 5.18,
"Case Mappings").

To achieve this, I have added a llvm::sys::unicode::foldCharSimple
function, which performs this mapping. The implementation of this
function was generated from the CaseMatching.txt file from the Unicode
spec using a python script (which is also included in this patch). The
script tries to optimize the function by coalescing adjecant mappings
with the same shift and stride (terms I made up). Theoretically, it
could be made a bit smarter and merge adjecant blocks that were
interrupted by only one or two characters with exceptional mapping, but
this would save only a couple of branches, while it would greatly
complicate the implementation, so I deemed it was not worth it.

Since we assume that the vast majority of the input characters will be
US-ASCII, the folding hash function has a fast-path for handling these,
and only whips out the full decode+fold+encode logic if we encounter a
character outside of this range. It might be possible to implement the
folding directly on utf8 sequences, but this would also bring a lot of
complexity for the few cases where we will actually need to process
non-ascii characters.

We are running lld tests with "--full-shutdown" option because we don't

is needed for leak sanitizer.

This patch changes the way how we tell lld that it is running tests.
Now "--full-shutdown" is removed, and LLD_IN_TEST environment variable
is used instead.

This patch enables full shutdown on all ports, e.g. ELF, COFF and wasm.
Previously, we enabled it only for ELF.

Sam McCall 2d8242d60d [gtest] Support raw_ostream printing functions more comprehensively.
Summary:
These are functions like operator<<(raw_ostream&, Foo).

Previously these were only supported for messages. In the assertion
  EXPECT_EQ(A, B) << C;
the local modifications would explicitly try to use raw_ostream printing for C.
However A and B would look for a std::ostream printing function, and often fall
back to gtest's default "168 byte object <00 01 FE 42 ...>".

This patch pulls out the raw_ostream support into a new header under `custom/`.

I changed the mechanism: instead of a convertible stream, we wrap the printed
value in a proxy object to allow it to be sent to a std::ostream.
I think the new way is clearer.

I also changed the policy: we prefer raw_ostream printers over std::ostream
ones. This is because the fallback printers are defined using std::ostream,
while all the raw_ostream printers should be "good".

Sander de Smalen 5b691a10c0 [TableGen][AsmMatcherEmitter] Fix tied-constraint checking for InstAliases
Summary:
This is a bit of a reimplementation the work done in
https://reviews.llvm.org/D41446, since that patch only really works for
tied operands of instructions, not aliases.

Instead of checking the constraints based on the matched instruction's opcode,
this patch uses the match-info's convert function to check the operand
constraints for that specific instruction/alias.
This is based on the matched operands for the instruction, not the
resulting opcode of the MCInst.

This patch adds the following enum/table to the *GenAsmMatcher.inc file:
  enum {
    Tie0_1_1,
    Tie0_1_2,
    Tie0_1_5,
    ...
  };

  const char TiedAsmOperandTable[][3] = {
    /* Tie0_1_1 */ { 0, 1, 1 },
    /* Tie0_1_2 */ { 0, 1, 2 },
    /* Tie0_1_5 */ { 0, 1, 5 },
    ...
  };

And it is referenced directly in the ConversionTable, like this:
static const uint8_t ConversionTable[CVT_NUM_SIGNATURES][13] = {
  ...
  { CVT_95_addRegOperands, 1,
    CVT_95_addRegOperands, 2,
    CVT_Tied, Tie0_1_5,
    CVT_95_addRegOperands, 6, CVT_Done },
  ...


The Tie0_1_5 (and corresponding table) encodes that:
* Result operand 0 is the operand to copy (which is e.g. done when
  building up the operands to the MCInst in convertToMCInst())
* Asm operands 1 and 5 should be the same operands (which is checked
  in checkAsmTiedOperandConstraints()).

Summary:
Apparently, we missed on constraining register classes of VReg-operands of all the instructions
built from a destination pattern but the root (top-level) one. The issue exposed itself
while selecting G_FPTOSI for armv7: the corresponding pattern generates VTOSIZS wrapped
into COPY_TO_REGCLASS, so top-level COPY_TO_REGCLASS gets properly constrained,
while nested VTOSIZS (or rather its destination virtual register to be exact) does not.

Fixing this by issuing GIR_ConstrainSelectedInstOperands for every nested GIR_BuildMI.

Benjamin Kramer cbce2f02e9 [TableGen] Optimize the regex search.
llvm::Regex is still the slowest regex engine on earth, running it over
all instructions on X86 takes a while. Extract a prefix and use a binary
search to reduce the search space before we resort to regex matching.

There are a couple of caveats here:
- The generic opcodes are outside of the sorted enum. They're handled in an extra loop.
- If there's a top-level bar we can't use the prefix trick.
- We bail on top-level ?. This could be handled, but it's rare.

This brings the time to generate X86GenInstrInfo.inc from 21s to 4.7s on
my machine.

Justin Bogner eaae305a09 update_mir_test_checks: Improve the check for LLVM IR in MIR files
The LLVM IR section of a MIR document can start with "--- |" rather
than just "---", because "|" is a sigil for a freeform document in
YAML. We need to handle this so that we don't try to add check lines
to the LLVM IR functions in a MIR file.

Dimitry Andric d05541f7d6 Add a -no-libcxxabi option to the test-release.sh script.
On FreeBSD, it is currently not possible to build libcxxabi and link
against it, so we have been building releases with -no-libs for quite
some time.

However, libcxx and libunwind should build without problems, so provide
an option to skip just libcxxabi.

Daniel Sanders 12e6e709e9 [globalisel][tablegen] Honour priority order within nested instructions.
It appears that we haven't been prioritizing rules that contain nested
instructions properly. InstructionOperandMatcher didn't override
isHigherPriorityThan so it never compared the instructions/operands/predicates
inside nested instructions.

Fixes PR35926. Thanks to Diana Picus for the bug report.
