attributes

Name	Description
`name`	`Name`, required. A unique name for this target.
`deps`	`List of labels`, optional, defaults to `[]`. The dependencies for this target. Use `ll_library` targets here. Other targets won't work.
`srcs`	`List of labels`, optional, defaults to `[]`. Compilable source files for this target. Allowed file extensions: `[".ll", ".o", ".S", ".c", ".cl", ".cpp"]`. Place headers in the `hdrs` attribute.
`data`	`List of labels`, optional, defaults to `[]`. Extra files made available to compilation and linking steps. Not appended to the default command line arguments, but available to actions. Reference these files manually for instance in the `includes`, and `compile_flags` attributes. Use this attribute to make intermediary outputs from non-ll targets, for example from `rules_cc` or `filegroup`, available to the rule.
`hdrs`	`List of labels`, optional, defaults to `[]`. Header files for this target. When including a header file with a nested path, for instance `#include "some/path/myheader.h"`, add `"some/path"` to `includes` to make it visible to the rule. Unavailable to downstream targets.
`angled_includes`	`List of strings`, optional, defaults to `[]`. Angled include paths, relative to the target workspace. Useful if you require include prefix stripping for dynamic paths, for instance the ones generated by `bzlmod`. Instead of `compile_flags = ["-Iexternal/mydep.someversion/include"]`, use `angled_includes = ["include"]` to add the path to the workspace automatically. Expands paths starting with `$(GENERATED)` to the workspace location in the `GENDIR` path. Unavailable to downstream targets.
`compilation_mode`	`String`, optional, defaults to `"cpp"`. Enables compilation of heterogeneous single source files. Prefer this attribute over adding SYCL/HIP/CUDA flags manually in the `compile_flags` and `link_flags`. See CUDA and HIP. `"cpp"` The default C++ toolchain. `"cuda_nvptx"` The CUDA toolchain. `"cuda_nvptx_nvcc"` The CUDA toolchain with `nvcc` as device compiler. `"hip_nvptx"` The HIP toolchain. `"bootstrap"` The bootstrap toolchain used by internal dependencies of the `ll_toolchain`.
`compile_flags`	`List of strings`, optional, defaults to `[]`. Flags for the compiler. Pass a list of strings here. For instance `["-O3", "-std=c++20"]`. Split flag pairs `-Xclang -somearg` into separate flags `["-Xclang", "-somearg"]`. Unavailable to downstream targets.
`compile_string_flags`	`List of labels`, optional, defaults to `[]`. Flags for the compiler in the form of `string_flag`s. Splits the values of each `string_flag` along colons like so: `load("@bazel_skylib//rules:common_settings.bzl", "string_flag") string_flag( name = "myflags", build_setting_default = "a:b:c", ) ll_library( # ... # Equivalent to compile_flags = ["a", "b", "c"] compile_string_flags = [":myflags"], )` Useful for externally configurable build attributes, such as generated flags from Nix environments.
`defines`	`List of strings`, optional, defaults to `[]`. Defines for this target. Pass a list of strings here. For instance `["MYDEFINE_1", "MYDEFINE_2"]`. Unavailable to downstream targets.
`depends_on_llvm`	`Boolean`, optional, defaults to `False`. Whether this target directly depends on targets from the `llvm-project-overlay`. Setting this to `True` makes the `cc_library` targets from the LLVM project overlay available to this target.
`experimental_device_intrinsics`	`List of labels`, optional, defaults to `[]`. Custom intrinsics for device compilation. Adds `-Xarch_device -include<thefile>` to the compile commands for this target.
`exposed_angled_includes`	`List of strings`, optional, defaults to `[]`. Exposed angled include paths, relative to the original target workspace. Expands paths starting with `$(GENERATED)` to the workspace location in the `GENDIR` path. Added to the compile command line arguments of direct dependents.
`exposed_defines`	`List of strings`, optional, defaults to `[]`. Exposed defines for this target. Added to the compile command line arguments of direct dependents.
`exposed_hdrs`	`List of labels`, optional, defaults to `[]`. Exposed headers for this target. Direct dependents can see exposed headers. Put the public API headers for libraries here.
`exposed_includes`	`List of strings`, optional, defaults to `[]`. Exposed include paths, relative to the original target workspace. Expands paths starting with `$(GENERATED)` to the workspace location in the `GENDIR` path. Added to the compile command line arguments of direct dependents.
`exposed_interfaces`	`Dictionary: Label -> String`, optional, defaults to `{}`. Transitive interfaces for this target. See C++ modules for a guide. Makes precompiled modules and compiled objects visible to direct dependents. Files in this attribute can see BMIs from modules in `interfaces`. Primary module interfaces go here.
`includes`	`List of strings`, optional, defaults to `[]`. Include paths, relative to the target workspace. Uses `-iquote`. Useful if you need custom include prefix stripping for dynamic paths, for instance the ones generated by `bzlmod`. Instead of `compile_flags = ["-iquoteexternal/mydep.someversion/include"]`, use `includes = ["include"]` to add the path to the workspace automatically. Expands paths starting with `$(GENERATED)` to the workspace location in the `GENDIR` path. Unavailable to downstream targets.
`interfaces`	`Dictionary: Label -> String`, optional, defaults to `{}`. Module interfaces for this target. See C++ modules for a guide. Makes precompiled modules and compiled objects visible to direct dependents and to `exposed_interfaces`. For instance, you can put module partitions in `interfaces` and the primary module interface in `exposed_interfaces`. Files in the same `interfaces` attribute can't see each other's BMIs.
`libraries`	`List of labels`, optional, defaults to `[]`. Libraries linked to the final executable. Adds these libraries to the command line arguments for the linker.
`link_flags`	`List of strings`, optional, defaults to `[]`. Flags for the linker. Place library search paths and external link targets here. Assuming you have a library `/some/path/libmylib.a` on your host system, you can make `mylib.a` available to the linker by passing `["-L/some/path", "-lmylib"]` to this attribute. Prefer the `libraries` attribute for library files already present within the Bazel build graph.
`link_string_flags`	`List of labels`, optional, defaults to `[]`. Flags for the linker in the form of `string_flag`s. See `compile_string_flags` for semantics. Prefer the `libraries` attribute for library files already present within the Bazel build graph.
`sanitize`	`List of strings`, optional, defaults to `[]`. Enable sanitizers for this target. See the Sanitizers guide. Some sanitizers come with heavy performance penalties. Enabling several sanitizers at the same time often breaks builds. If possible, use just one at a time. Sanitizers produce nondeterministic error reports. Run sanitized executables several times and build them with different optimization levels to maximize coverage. `"address"`: Enable AddressSanitizer to detect memory errors. `"leak"`: Enable LeakSanitizer to detect memory leaks. `"memory"`: Enable MemorySanitizer to detect uninitialized reads. `"undefined_behavior"`: Enable UndefinedBehaviorSanitizer to detect undefined behavior. `"thread"`: Enable ThreadSanitizer to detect data races.
`toolchain_configuration`	`Label`, optional, defaults to `"@rules_ll//ll:current_ll_toolchain_configuration"`. TODO
