The original JAM compiler was first implemented by Joe Armstrong. The original BEAM compiler (v1) was first implemented by Bogumil Hausman. The original v2 and v3 compilers were implemented by Robert Virding. Bj�rn Gustavsson adapted the code generation for the BEAM machine and added the optimisation passes. General improvements and corrections were made by Robert Virding, Arndt Jonasson, Tony Rogvall, Bj�rn Gustavsson and Jan-Erik Dahlin. The bit syntax support was implemented by Bj�rn Gustavsson, Arndt Jonasson and Robert Virding. The Core Erlang is used as an intermediate format in the v3 compiler (R7). Core Erlang was suggested by Richard Carlsson (HiPE). The new inliner in R8 is written by Richard Carlsson (HiPE). Updates, extensions, and bugfixes in the R8 compiler were made by Robert Virding, Richard Carlsson (HiPE), and Bj�rn Gustavsson. Bjorn Gustavsson and Raimo Niskanen implemented the beam_validator compiler pass for R10B-2 (it makes that the compiler did not generate code that could crash the run-time system). The current maintainer of the compiler is Bjorn Gustavsson. To the R12B he added a simple form of stack trimming, as well as other optimizations.
