Changelog

[2.1.0] - 2018-11-01

Added

  • tracepoint provider to use the kernel's stable tracepoints.
  • delete keyword to remove associations from a map.
  • Numeric constants can now be in binary using the 0b prefix.
  • Numeric constants can be grouped by insering _'s, i.e. one million could be written as 1_000_000 a 32-bit address could be written as 0xc1ab_dead

Fixed

  • Architecture specific files are now a part of the distribution tarball (#10).
  • Multiple off-by-one issues with string literals have been fixed (#14).
  • Unary operators now work with arguments that require AST rewrites (#11).

[2.0.0] - 2018-10-18

The entire compiler has been re-written using the lessons learned from the limitations of v1. There is now a proper type system that be extended to describe all C types, there is an intermediate representation (IR) that makes instruction selection much easier. Some NIH accidents regarding the grammar have been corrected to align with existing work (DTrace). Error messages on invalid scripts should be more helpful, though there is still much to be done in this area.
