1.25.23

Features:

• all deprecated macros are gone. All macros are typed macros now
• all macros 1.0 infrastructure is gone
• removed quite a bit of dead code
• back down to 6189 total lines of code

1.25.22

Features:

• all but one macro moved to macros 2.0
• quite a bit faster, not a lot of memory saved

1.25.21

Features:

• remove small type allocations and replace with constants
• only small performance improvements

1.25.20

Features:

• add a term count profiler that counts how many terms are allocated before and after preprocessing/typechecking
• add support for suffix rewriting in macros 2.0
• move some core macros to macros 2.0 (no significant performance impact so far)
• move some redundant temporary allocations to be constants
  • it is easy to underestimate how impactful this would be
  • t2(c"Arrow", t0(c"Any"), t0(c"Any")) creates at least 3 new heap allocations
• down to 9.5GB run allocation for GC-disabled compiler
• down to 7.8 minutes for all tests to run from 9.5 minutes last commit

1.25.19

Features:

• new Type case TId for numerical ids
• change Phi::Ids to use TIds instead of string identifiers
• integers don't use any heap memory
• integers are very fast to compare because they never need to load indirect memory like strcmp
• about 10-20x speedup and significantly reduced memory usage for GC enabled compiler
• full test suite takes 9.5 minutes to run with GC enabled for all tests

1.25.18

Features:

• replace memset calls with universal zero initializer (7% speedup overall)
• silence a linear leaked variable in if cases
  • this needs to be released not ignored, so next commit will fix this
  • otherwise it would be a memory leak

1.25.17

Features:

• moved AST.Typedef case from direct declaration to indirect declaration behind a pointer
• this reduces the size of the AST type by 90%
• speed is improved by about 30% (somehow memory size reduction helps here with zeroing and moves)
• resulting in a total memory usage reduction in the compiler of 40% (9GB total with GC disabled)
• PCTX was heavily affected by this because it contains a blame field and has many rows
• so this will affect the memory usage of GC-enabled compiler more than current one

1.25.16

Features:

• greatly reduced absolute number of memory allocations
• down to 14GB total

1.25.15

Features:

• add ability to count type allocations to profile memory usage
• lots of type allocations (potentially, hard to get rid of)
• lots of U8, and S allocations (no idea why this is so high)

1.25.14

Features:

• move a few more data structures from List to Vector
• ~5% performance improvement runtime and memory usage
