0.15

New Features:

  • Added a new --no-simplify option to disable Seafoam’s graph simplification (#66, @chrisseaton).
  • Updated the synthetic Truffle argument nodes to use our packed argument name rather than an index offset (e.g., T(5) -> T(SELF) and T(8) -> T(args[0])) (#72, @nirvdrum).

Bug Fixes:

  • Fixed issue with Truffle arg simplification where some edges could fail to simplify (#69, @nirvdrum).

  • Removed hidden nodes from the describe command output (#66, @chrisseaton).
  • Improved the describe command output to ignore hidden nodes (@chrisseaton).
  • Added more “triggers” to detect if we’re looking at Graal or Truffle graphs (as opposed to regular JVM graphs) (@chrisseaton).
  • Support simplifying more allocation node classes (#67, @nirvdrum).

0.14

New Features:

  • Added a histogram of nodes in the describe command output (#52, @eregon).

Bug Fixes:

Changes:

  • Hide BeginNode and EndNode in graphs (#59, @eregon).
  • Split the "effect" kind into "alloc", "call", "memory", and "sync", each with a different color, for easier identification (#59, @eregon).
  • Enhanced the style of Mermaid graphs (#61, @chrisseaton).
  • Enhanced allocation node simplification by replacing various allocation nodes with a single node per new object (#63, @eregon)

0.13

Bug Fixes:

Changes:
