CPunch cd37cfdae5 cparse: removed stale expressionStatement forward declare 2023-12-29 18:01:33 -06:00
cpunch e0455902b0 'return' is now a valid statement outside of a function 
lets us do some cool things later. also the repl can print returned values. eg.

`return "hello world"` will print `<string> "hello world"` to the console

CPunch 89be01aaf6 even more error handling refactoring 
removing all of these useless checks has actually made cosmoV_execute just a
lil bit faster :)
 2023-09-04 20:14:53 -05:00

CPunch 6126b50941 cosmoV_throw() now resets the vm stack as well 
also a minor GC bug in cosmoO_newError was fixed.

i'm going to try to phase out cosmoM_freezeGC & friends
since that would cause hell with this new
error handling solution. the only thing still using it is the GC.
 2023-08-29 16:48:38 -05:00
CPunch 7fa7eb8d94 fixed minor memory leak in cparse 
we keep track of internal values used by the parser by pushing them onto the stack
and popping them off once complete.

CPunch 0633e87aa6 WIP: removed stale error handling 
currently, scripts seem to run fine. however I'm a bit worried about stack related issues. maybe i'll need to reset state->top as well? but not entirely sure

CPunch 2b3825d258 implemented jump table dispatch 
- currently only enabled on supported platforms (GNU C Compiler + Clang)
- when enabled, sped up examples/fibtest.cosmo by about 20% (avg of 11.179s prior and 8.799 after)

NOTE: malicious dumps can trivially cause crashes now by having junk function chunks
