d8c87888a7 Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for fixed-length instruction encodings.
A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks
provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen
like the existing disassembly emitters do.

The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove
some of the hacks the old one introduced to tblgen.

214c920818 lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this.
FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

a2b6e4151b Fix encoding and add parsing support for the arm/thumb CPS instruction:
- Add custom operand matching for imod and iflags.
- Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC
  from mnemonic.
- While adding ".w" as an operand, don't change "Head" to avoid passing the
  wrong mnemonic to ParseOperand.
- Add asm parser tests.
- Add disassembler tests just to make sure it can catch all cps versions.

f922c47143 AsmMatcher custom operand parser failure enhancements.
Teach the AsmMatcher handling to distinguish between an error custom-parsing
an operand and a failure to match. The former should propogate the error
upwards, while the latter should continue attempting to parse with
alternative matchers.

Update the ARM asm parser accordingly.

b9db0c50d8 Do AsmMatcher operand classification per-opcode.
When matching operands for a candidate opcode match in the auto-generated
AsmMatcher, check each operand against the expected operand match class.
Previously, operands were classified independently of the opcode being
handled, which led to difficulties when operand match classes were
more complicated than simple subclass relationships.

1aac1864cf emit a specific error when the input file is empty. This fixes
an annoyance of mine when working on tests: if the input .ll file
is broken, opt outputs an error and generates an empty file.  FileCheck
then emits its "ooh I couldn't find the first CHECK line, scanning
from ..." which obfuscates the actual problem.

e7a54520b3 Implement support for custom target specific asm parsing of operands.
Motivation: Improve the parsing of not usual (different from registers or
immediates) operand forms.

This commit implements only the generic support. The ARM specific modifications
will come next.

A table like the one below is autogenerated for every instruction
containing a 'ParserMethod' in its AsmOperandClass

static const OperandMatchEntry OperandMatchTable[20] = {
 /* Mnemonic, Operand List Mask, Operand Class, Features */
 { "cdp", 29 /* 0, 2, 3, 4 */, MCK_Coproc, Feature_IsThumb|Feature_HasV6 },
 { "cdp", 58 /* 1, 3, 4, 5 */, MCK_Coproc, Feature_IsARM },

A matcher function very similar (but lot more naive) to
MatchInstructionImpl scans the table. After the mnemonic match, the
features are checked and if the "to be parsed" operand index is
present in the mask, there's a real match. Then, a switch like the one
below dispatch the parsing to the custom method provided in
'ParseMethod':

 case MCK_Coproc:
   return TryParseCoprocessorOperandName(Operands);

685c350ae7 Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.
(yes, this is different from R_ARM_CALL)

- Adds a new method getARMBranchTargetOpValue() which handles the
  necessary distinction between the conditional and unconditional br/bl
  needed for ARM/ELF

At least for ARM mode, the needed fixup for conditional versus unconditional
br/bl is identical, but the ARM docs and existing ARM tools expect this
reloc type...

Added a few FIXME's for future naming fixups in ARMInstrInfo.td

79fcb6dec3 Changed the TableGen created MatchInstructionImpl() setting of ErrorInfo.
The algorithm for identifying which operand is invalid will now always point to
some operand and not the mnemonic sometimes.  The change is now that ErrorInfo
is the index of the highest operand that does not match for any of the matching
mnemonics records.  And no longer the ~0U value when the mnemonic matches and
not every record with a matching mnemonic has the same mismatching operand
index.

9d7f011110 [AVX] Implement EnforceSmallerThan for mixed int/fp type lists. This
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

a49c7dfb36 Improve the AsmMatcher's ability to handle suboperands.
When an operand class is defined with MIOperandInfo set to a list of
suboperands, the AsmMatcher has so far required that operand to also define
a custom ParserMatchClass, and InstAlias patterns have not been able to
set the individual suboperands separately.  This patch removes both of those
restrictions.  If a "compound" operand does not override the default
ParserMatchClass, then the AsmMatcher will now parse its suboperands
separately.  If an InstAlias operand has the same class as the corresponding
compound operand, then it will be handled as before; but if that check fails,
TableGen will now try to match up a sequence of InstAlias operands with the
corresponding suboperands.
