This patch resubmits the SVE ZIP1/ZIP2 patch series consisting of
of r320992, r320986, r320973, and r320970 by reverting
https://reviews.llvm.org/rL321024.
The issue that caused r321024 has been addressed in https://reviews.llvm.org/rL321158,
so this patch-series should be safe to resubmit.
llvm-svn: 321163
This reverts changes r320992, r320986, r320973, and r320970.
r320970 by itself breaks the test case, and the rest depend on it.
Test case will land soon.

Summary:
When emitting a diagnostic for an invalid operand, a specific diagnostic
should only be reported when the instruction being matched is actually
enabled by the feature flags.
Patch [3/4] in a series to add parsing of predicates and properly parse SVE
ZIP1/ZIP2 instructions. This patch fixes bogus diagnostic messages for when
the SVE feature is not specified.

These instructions were previously marked as codegen only preventing
them from being assembled as microMIPS or disassembled.

Previously these instructions were marked codegen only and had
an under-specified instruction description that did not record the
fcc register.

Permit explicit $fcc<X> operand in c.cond.fmt instruction.
Add c.cond.fmt to the MIPS to microMIPS instruction mapping table.
Check that $fcc1 - $fcc7 are unusable for MIPS-I to MIPS-III for
c.cond.fmt, bc1t, bc1f.

This patch adds the single operand form of the not alias to microMIPS and
MIPS along with additional tests.
This partially resolves PR/30381.
Thanks to Sean Bruno for reporting the issue!

Add synci to the microMIPS instruction definitions, mark the MIPS sync & synci
as not being part of microMIPS. This does not cover the sync instruction alias,
as that will be handled with a different patch. Add sync to the valid tests for
microMIPS.

Commit r266977 was reason for failing LLVM test suite with error message: fatal error: error in backend: Cannot select: t17: i32 = rotr t2, t11 ...

Summary:
The bug was that microMIPS's [ls]w[lr]e instructions claimed to support a
12-bit offset when it is only 9-bit.

Summary:
Also renamed li_simm7 to li16_imm since it's not a simm7 and has an unusual
encoding (it's a uimm7 except that 0x7f represents -1).

Summary:
The bug was that dextu's operand 3 would print 0-31 instead of 32-63 when
printing assembly. This came up when replacing
MipsInstPrinter::printUnsignedImm() with a version that could handle arbitrary
bit widths.
MipsAsmPrinter::printUnsignedImm*() don't seem to be used so they have been
removed.

Summary:
The bugs were:
* append, prepend, and balign were not tested
* balign takes a uimm2 not a uimm5.
* drotr32 was correctly implemented with a uimm5 but the tests expected
'52' to be valid.
* li/la were implemented with a uimm5 instead of simm32. simm32 isn't
completely correct either but I'll fix that when I get to simm32.
A notable omission are some of the shift instructions. Several of these
have been implemented using a single uimm6 instruction (rather than two
uimm5 instructions and a CodeGen-only uimm6 pseudo). These will be updated
in the uimm6 patch.

Summary:
The bug was that the sldi instructions have immediate widths dependant on
their element size. So sldi.d has a 1-bit immediate and sldi.b has a 4-bit
immediate. All of these were using 4-bit immediates previously.
