Roman Lebedev fbb823891d [llvm-exegesis] Fix serialization/deserialization of special NoRegister register (PR41448)
Summary:
A *lot* of instructions have this special register.
It seems this never really worked, but i finally noticed it only
because it happened to break for `CMOV16rm` instruction.

We serialized that register as "" (empty string), which is naturally
'ignored' during deserialization, so we re-create a `MCInst` with
too few operands.

And when we then happened to try to resolve variant sched class
for this mis-serialized instruction, and the variant predicate
tried to read an operand that was out of bounds since we got less operands,
we crashed.

Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=41448 | PR41448 ]].

Fangrui Song 6a285dfe71 [DWARF] Set discriminator to 0 for DW_LNS_copy
Summary:
Make DW_LNS_copy set the discriminator register to 0, to conform to
DWARF 4 & 5: "Then it sets the discriminator register to 0, and sets the
basic_block, prologue_end and epilogue_begin registers to false."

Because all of DW_LNE_end_sequence, DN_LNS_copy, and special opcodes reset
discriminator to 0, we can move discriminator=0 to appendRowToMatrix.

Also, make DW_LNS_copy print before appending the row, as it is similar
to a address+=0,line+=0 special opcode, which prints before appending
the row.

Craig Topper 61f31cbcb2 [X86] Teach foldMaskedShiftToScaledMask to look through an any_extend from i32 to i64 between the and & shl
foldMaskedShiftToScaledMask tries to reorder and & shl to enable the shl to fold into an LEA. But if there is an any_extend between them it doesn't work.

This patch modifies the code to look through any_extend from i32 to i64 when the and mask only uses bits that weren't from the extended part.

This will prevent a regression from D60358 caused by 64-bit SHL being narrowed to 32-bits when their upper bits aren't demanded.

Craig Topper 4a32ce39b7 [X86] Make _Int instructions the preferred instructon for the assembly parser and disassembly parser to remove inconsistencies between VEX and EVEX.
Many of our instructions have both a _Int form used by intrinsics and a form
used by other IR constructs. In the EVEX space the _Int versions usually cover
all the capabilities include broadcasting and rounding. While the other version
only covers simple register/register or register/load forms. For this reason
in EVEX, the non intrinsic form is usually marked isCodeGenOnly=1.

In the VEX encoding space we were less consistent, but usually the _Int version
was the isCodeGenOnly version.

This commit makes the VEX instructions match the EVEX instructions. This was
done by manually studying the AsmMatcher table so its possible I missed some
cases, but we should be closer now.

I'm thinking about using the isCodeGenOnly bit to simplify the EVEX2VEX
tablegen code that disambiguates the _Int and non _Int versions. Currently it
checks register class sizes and Record the memory operands come from. I have
some other changes I was looking into for D59266 that may break the memory check.

I had to make a few scheduler hacks to keep the _Int versions from being treated
differently than the non _Int version.

Jonas Devlieghere 8b3af63b89 [NFC] Remove ASCII lines from comments
A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.

Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.

I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

Craig Topper 87a8f9761e [X86] Replace some if statements in isel address matching that should never be true with asserts. And move them earlier before we looked through operands that don't change size. NFC
These ifs were ensuring we don't have to handle types larger than 64 bits probably because we use getZExtValue in several places below them.

None of the callers of this code pass types larger than 64-bits so we can just assert instead of branching in release code.

I've also moved them earlier since we're just looking through operations that don't effect bit width.

This is prep work for some refactoring I plan to do to the (and (shl)) handling code.

Nick Desaulniers ad8f3a1440 [X86AsmPrinter] refactor to limit use of Modifier. NFC
Summary:
The Modifier memory operands is used in 2 cases of memory references
(H & P ExtraCodes). Rather than pass around the likely nullptr Modifier,
refactor the handling of the Modifier out from printOperand().

The refactorings in this patch:
- Don't forward declare printOperand, move its definition up.
  - The diff makes it look like there's a change to printPCRelImm
    (narrator: there's not).
- Create printModifiedOperand()
  - Move logic for Modifier to there from printOperand
  - Use printModifiedOperand in 3 call sites that actually create
    Modifiers.
- Remove now unused Modifier parameter from printOperand
- Remove default parameter from printLeaMemReference as it only has 1
  call site that explicitly passes a parameter.
- Remove default parameter from printMemReference, make call lone call
  site explicitly pass nullptr.
- Drop Modifier parameter from printIntelMemReference, as Intel style
  memory references don't support the Modifiers in question.

This will allow future changes to printOperand() to make it a pure virtual
method on the base AsmPrinter class, allowing for more generic handling
of some architecture generic constraints. X86AsmPrinter was the only
derived class of AsmPrinter to have additional parameters on its
printOperand function.
