Module llvm

Source
Expand description

The LLVM backend: intrinsics, the host system and the CPUs and features of LLVM targets.

The functions of python/tvm_tirx/codegen/llvm.py, and the host queries python/tvm_tirx/target/detect_target.py makes. A query that takes an optional target falls back to the current one, and answers nothing for a target that is not llvm.

Functionsยง

  • cpu_has_feature
    Whether the CPU of target has the feature feature (codegen.llvm_cpu_has_feature).
  • get_cpu_archlist
    The CPUs of the -mtriple of target (codegen.llvm_get_cpu_archlist).
  • get_cpu_features
    The CPU features of the -mtriple, -mcpu and -mattr of target (codegen.llvm_get_cpu_features).
  • get_default_target_triple
    The default LLVM target triple of the host (tvm.codegen.llvm.GetDefaultTargetTriple).
  • get_host_cpu_features
    The features of the host CPU, each with a boolean saying whether it is enabled; empty when LLVM cannot tell (tvm.codegen.llvm.GetHostCPUFeatures).
  • get_host_cpu_name
    The LLVM name of the host CPU (tvm.codegen.llvm.GetHostCPUName).
  • get_intrinsic_name
    The name of the LLVM intrinsic intrin_id (codegen.llvm_get_intrinsic_name).
  • get_process_triple
    The LLVM target triple of the running process (tvm.codegen.llvm.GetProcessTriple).
  • get_system_cpu
    The LLVM name of the host CPU (codegen.llvm_get_system_cpu).
  • get_system_triple
    The default LLVM target triple of the host (codegen.llvm_get_system_triple).
  • get_system_x86_vendor
    The vendor of the host x86 CPU: intel, amd, unknown, or unimplemented on other CPUs (codegen.llvm_get_system_x86_vendor).
  • get_targets
    The LLVM targets LLVM was built with (codegen.llvm_get_targets).
  • get_vector_width
    The vector width of the CPU of target, in bits; -1 for a target that is not llvm (codegen.llvm_get_vector_width).
  • is_valid_cpu
    Whether LLVM knows the CPU cpu for the target triple triple (codegen.llvm_is_valid_cpu).
  • lookup_intrinsic_id
    The id of the LLVM intrinsic name, 0 when there is none (codegen.llvm_lookup_intrinsic_id).
  • target_enabled
    Whether LLVM can create a target machine for the target string target, such as "llvm -mtriple=aarch64-linux-gnu" (codegen.llvm_target_enabled).
  • version_major
    The major version of LLVM (codegen.llvm_version_major).
