0.3.2

[0.3.2] - 2016-09-18

Fixed

• The ponyc version is now consistently set from the VERSION file.
• Stop generating llvm.invariant.load intrinsic for "let" references, as these don't necessarily match the semantics of that intrinsic.

Changed

• The setversion and release commands have been removed from Makefile.
• LTO is again enabled by default on OSX
• make now builds a release rather than debug build by default

0.3.1

[0.3.1] - 2016-09-14

Fixed

• Make sure all scheduler threads are pinned to CPU cores; on Linux/FreeBSD this wasn't the case for the main thread.
• Account for both hyperthreading and NUMA locality when assigning scheduler threads to cores on Linux.
• Stop generating llvm.invariant.start intrinsic. It was causing various problems in code generation.
• Buffer overflow triggerable by very long ponyc filename (issue #1177).
• Assertion failure in optimisation passes.
• Race condition in scheduler queues on weakly-ordered architectures.
• Issue #1212 by reverting commit e56075d

Added

• --ponypinasio runtime option for pinning asio thread to a cpu core.
• --ponynopin runtime option for not pinning any threads at all.

Changed

• Path.base now provides option to omit the file extension from the result.
• Map.upsert returns value for upserted key rather than this.
• ponyc --version now includes llvm version in its output.
• LTO is now disabled by default on OSX.
