- Determine memory operands by there membership of patterns.
Operands can be defined via patterns. The pattern has a type itself.
Patterns are commonly used to define memory operands
(as a collection of multiple other operands).
Here we check, if the operand is part of a pattern with type iPTR.
Type iPTR indicates a memory operand.
- Search for unspecified instruction patterns and extract memory op info from them.
AArch64 has the case of patterns which are not set in the CGI class.
Instead those patterns are free floating in the record keeper.
With this commit we first collect all such unassigned patterns and save them in a map
(indexed by instruction name they belong to).
When instruction operand details are generated, the operand type is searched in the pattern of the instruction.
If there is an operand with the same type in the pattern, which is also of a iPTR pattern, we treat it as memory operand.
Note that we can not compare the operands of the instruction and the pattern operands by name.
Because they simply are not named the same way.
This is a short coming in the td files and should be addressed in LLVM.
Because it is enormiously hard to get a 1 to 1 mapping from a pattern to an instruction
and its operands.
The MCInstDesc table changed. Bsides this only minor changes were done
and some additional code is emitted now for LLVM.
This commit is the combination of all previous Auto-Sync commits.
The list of commit messages follows:
-----------
Combination of all commits of the refactored tablegen backends.
These are the changes made for LLVM 16.
Refactor Capstone relevant TableGen Emitter backends.
This commit extracts the code which emits generated tables into two printer classes.
The Printer is called whenever actual code is written to a file.
There is the PrinterLLVM which emits tht code as before and
PrinterCapstone which is tailored to or needs (emitting C and generates
more info).
Additionally missing memory access properties were added to ARMs td
files.
Emit a single header for all files.
Captialize Target name for enums.
Add lay metric to emit enum value for Banked and system regs.
Malloc substr
Sort instructions in ascending order.
Free substr after use
Add vanished constrainsts
Fix `regInfoEmitEnums()` and indent
Fix `GenDisassemblerTables.inc#checkDecoderPredicate()`
Fix `TriCoreGenRegisterInfo.inc` | `PrinterCapstone::regInfoEmitRegClasses`
revert changes to NEON instructions
Add instructions with duplicate operands as Matchables.
Add memory load and store info
Correct memory access and out operand info
Set register lists again as read ops due to https://github.com/llvm/llvm-project/issues/62455
Make printAliasInstr and getMnemonic static.
Generate CS instruction enums from actual mnemonic. Not via the flawed AsmMatcher.
Fix typo in InstrInfoEmitter.cpp
Add deprecated QPX feature
Replace + and - with p and m
Add AssemblerPredicates to PPC
Generate RegEncodingTable
Define functions which are called by the Mapper as static.
Necessary because these functions are present in each arch'
Remove set_mem_access().
The cases where this is used to mark access to actual memory operands are
either very rare, or those are neon lane indicies.
Generate correct op type for absolute addresses.
Check for RegisterPointer operands first to prevent mis-categorization.
Add missing Operand types
Generate Instruction formats for PPC.
Add Paired Single instructions.
Partly revert 94e41ce23a7fd863a96288ec05b6c7202c3cfbf1 (introduces accidentially removed code.)
Set correct operand types for PS operands
Add memory read/write attributes
Add missing operand types
Add mayLoad and mayStore information.
Add documentation.
Handle special AArch64 operand
Replace C++ with C code.
Check for duplicate enum instr. names
Check for duplicate defintions of system registers.
Add note about missing target names.
Resolve templates in a single static method and add docs about it.
Revert printing target name in upper case.
Revert partially C++ syntax fixes in .td files.
They break the TemplateCOllector since it searches for exactly those references but can't find any'
Add all SubtargetFeatures to feature enum.
Not just the one used by CGIs.
Pass Decoder
Enable to check specific table fields to determine if reg enum must be emitted.
Allow to add namespace to type name/
Formatting
Rework emitting of tables.
The system operands are now emitted in reg, imm and aliass groups.
Also a bug was fixed which emitted incorrect code..
Check for rename IMPLICIT_IMM operand types
Pass DecodeComplete as pointer not as reference
Print undef when it needs to be printed.
Add namespace ids to all types and functions.
Rework C translation.
Pass MCOp as pointer not as ref
Add missing SysImm type
Fix syntax mistakes
Generate additonal sys immediates and op groups.
Handle edge case for printSVERegOp
Handle default arguments of template functions.
Add two missing op groups
Generate a static RecEncodingTable
Set enum values to encodings of the sys ops
Generate a single Enum value file for system operands.
Replace System operand groups with their operand types
Fix missing braces warning
Emit MCOperand validator.
Emit lookupByName functions for sys operands
Add namespaces for ARM.
Check for Target if default arguments of template functions are resolved.
auto-sync opcode & operand encoding info generation (#14)
* Added operand and opcode info generation
* Wrapped deprecated macro under an intellisense check
Basically intellisense fails, causing multiple errors in other files,
so when intellisense parses the code it will use the different version of the macro
* Fixed a small bug
Used double braces to prevent an old bug
Removed extra new line and fixed a bug regarding move semantics
When speculating an instruction in `InstCombinerImpl::FoldOpIntoSelect`,
the call may result in undefined behavior. This patch drops all
UB-implying attrs/metadata to fix this.
Fixes#85536.
(cherry picked from commit 252d01952c087cf0d141f7f281cf60efeb98be41)
As noted in <https://github.com/llvm/llvm-project/pull/78537>, MSVC
places import descriptors in both the EC and regular map - that PR moved
the descriptors to ONLY the regular map, however this causes linking
errors when linking as Arm64EC:
```
bcryptprimitives.lib(bcryptprimitives.dll) : error LNK2001: unresolved external symbol __IMPORT_DESCRIPTOR_bcryptprimitives (EC Symbol)
```
This change copies import descriptors from the regular map to the EC
map, which fixes this linking error.
ARM64EC import libraries expose two additional symbols: mangled thunk
symbol (like `#func`) and auxiliary import symbol (like`__imp_aux_func`).
The main functional change with this patch is that those symbols are
properly added to static library ECSYMBOLS.
getExportName implementation is based on lld-link. In its current form,
it's mostly about convenience, but it will be more useful for EXPORTAS
support, for which export name is not possible to deduce from other
printed properties.
