14 days[NFC][DecoderEmitter] Code cleanup in `DecoderEmitter::emitTable` (#158014)Rahul Joshi1-0/+1
Several code cleanup changes in code to emit decoder tables: - Start comments on each line at a fixed column for readibility. - Combine repeated code to decode and emit ULEB128 into a single function. - Add helper `getDecoderOpName` to print decoder op. - Print Filter/CheckField/predicate index values with those opcodes.

2025-08-16[Hexagon] Add missing operand when disassembling Y4_crswap10 (#153849)Sergei Barannikov1-0/+3
Auto-generated decoder fails to add the $sgp10 operand because it has no encoding bits. Work around this by adding the missing operand after decoding is complete. Fixes #153829.
2025-07-18[Hexagon][llvm-objdump] Improve disassembly of Hexagon bundles (#145807)quic-areg1-24/+85
Hexagon instructions are VLIW "bundles" of up to four instruction words encoded as a single MCInst with operands for each sub-instruction. Previously, the disassembler's getInstruction() returned the full bundle, which made it difficult to work with llvm-objdump. For example, since all instructions are bundles, and bundles do not branch, branch targets could not be printed. This patch modifies the Hexagon disassembler to return individual sub-instructions instead of entire bundles, enabling correct printing of branch targets and relocations. It also introduces `MCDisassembler::getInstructionBundle` for cases where the full bundle is still needed. By default, llvm-objdump separates instructions with newlines. However, this does not work well for Hexagon syntax: { inst1 inst2 inst3 inst4 <branch> } :endloop0 Instructions may be followed by a closing brace, a closing brace with `:endloop`, or a newline. Branches must appear within the braces. To address this, `PrettyPrinter::getInstructionSeparator()` is added and overridden for Hexagon.
2025-06-17[llvm] annotate interfaces in llvm/Target for DLL export (#143615)Andrew Rogers1-1/+3
## Purpose This patch is one in a series of code-mods that annotate LLVM’s public interface for export. This patch annotates the `llvm/Target` library. These annotations currently have no meaningful impact on the LLVM build; however, they are a prerequisite to support an LLVM Windows DLL (shared library) build. ## Background This effort is tracked in #109483. Additional context is provided in [this discourse](https://discourse.llvm.org/t/psa-annotating-llvm-public-interface/85307), and documentation for `LLVM_ABI` and related annotations is found in the LLVM repo [here](https://github.com/llvm/llvm-project/blob/main/llvm/docs/InterfaceExportAnnotations.rst). A sub-set of these changes were generated automatically using the [Interface Definition Scanner (IDS)](https://github.com/compnerd/ids) tool, followed formatting with `git clang-format`. The bulk of this change is manual additions of `LLVM_ABI` to `LLVMInitializeX` functions defined in .cpp files under llvm/lib/Target. Adding `LLVM_ABI` to the function implementation is required here because they do not `#include "llvm/Support/TargetSelect.h"`, which contains the declarations for this functions and was already updated with `LLVM_ABI` in a previous patch. I considered patching these files with `#include "llvm/Support/TargetSelect.h"` instead, but since TargetSelect.h is a large file with a bunch of preprocessor x-macro stuff in it I was concerned it would unnecessarily impact compile times. In addition, a number of unit tests under llvm/unittests/Target required additional dependencies to make them build correctly against the LLVM DLL on Windows using MSVC. ## Validation Local builds and tests to validate cross-platform compatibility. This included llvm, clang, and lldb on the following configurations: - Windows with MSVC - Windows with Clang - Linux with GCC - Linux with Clang - Darwin with Clang

2022-09-08[llvm] Use std::size instead of llvm::array_lengthofJoe Loser1-4/+4
LLVM contains a helpful function for getting the size of a C-style array: `llvm::array_lengthof`. This is useful prior to C++17, but not as helpful for C++17 or later: `std::size` already has support for C-style arrays. Change call sites to use `std::size` instead.

2022-05-25[MCDisassembler] Disambiguate Size parameter in tryAddingSymbolicOperand()Maksim Panchenko1-1/+2
MCSymbolizer::tryAddingSymbolicOperand() overloaded the Size parameter to specify either the instruction size or the operand size depending on the architecture. However, for proper symbolic disassembly on X86, we need to know both sizes, as an instruction can have two operands, and the instruction size cannot be reliably calculated based on the operand offset and its size. Hence, split Size into OpSize and InstSize. For X86, the new interface allows to fix a couple of issues: * Correctly adjust the value of PC-relative operands. * Set operand size to zero when the operand is specified implicitly.

2020-08-03[MC] Fix memory leak when allocating MCInst with bump allocatorhgreving1-3/+3
Adds the function createMCInst() to MCContext that creates a MCInst using a typed bump alloctor. MCInst contains a SmallVector<MCOperand, 8>. The SmallVector is POD only for <= 8 operands. The default untyped bump pointer allocator of MCContext does not delete the MCInst, so if the SmallVector grows, it's a leak. This fixes https://bugs.llvm.org/show_bug.cgi?id=46900.

Summary: For builds with LLVM_BUILD_LLVM_DYLIB=ON and BUILD_SHARED_LIBS=OFF this change makes all symbols in the target specific libraries hidden by default. A new macro called LLVM_EXTERNAL_VISIBILITY has been added to mark symbols in these libraries public, which is mainly needed for the definitions of the LLVMInitialize* functions. This patch reduces the number of public symbols in libLLVM.so by about 25%. This should improve load times for the dynamic library and also make abi checker tools, like abidiff require less memory when analyzing libLLVM.so One side-effect of this change is that for builds with LLVM_BUILD_LLVM_DYLIB=ON and LLVM_LINK_LLVM_DYLIB=ON some unittests that access symbols that are no longer public will need to be statically linked.

2017-06-06Sort the remaining #include lines in include/... and lib/....Chandler Carruth1-3/+3
I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
