Late IPA passes (GNU Compiler Collection (GCC) Internals) (original) (raw)

8.4.3 Late IPA passes ¶

Late IPA passes are simple IPA passes executed after the regular passes. In WHOPR mode the passes are executed after partitioning and thus see just parts of the compiled unit.

• Materialize all clones
  Once all functions from compilation unit are in memory, produce all clones and update all calls. It is located in ipa.cc and is described bypass_materialize_all_clones.
• IPA points-to analysis
  Points-to analysis; this is the same as the points-to-analysis pass run with the small IPA passes (see Small IPA passes).
• OpenMP simd clone
  This is the OpenMP constructs’ SIMD clone pass. It creates the appropriate SIMD clones for functions tagged as elemental SIMD functions. It is located in omp-simd-clone.cc and is described bypass_omp_simd_clone.
