* compiler: update list of constant and effect-free functions.Kaz Kylheku2024-04-051-25/+28
| | | | | | | | | | | | | | | * stdlib/constfun.tl (%const-foldable-funs%): Numerous functions added, mostly new ones. (%effect-free-funs%): Indentation fixed. Some functions added, but also removed. We don't want anything in here that could take a functional argument. The optimizer will blindly a call to an effect-free function, if its result is not used, regardless of what the arguments are. It won't take into consideration that there is a functional argument, which could be a function that has a side effect, and that is called by the supposedly effect-free function. So for instance, sort is out; the comparison or key functions could have side effects. We could put these functions into a special category.

* constantp: fully expand; recognize functions.Kaz Kylheku2021-06-281-0/+63
This patch improves the constantp function dramatically. It now performs a full expansion of its argument, and recognizes all of the constant foldable functions that the compiler recognizes. * eval.c (const_foldable_s): New symbol variable. (const_foldable_hash): New static variable. (constantp_noex): Look up function in the hash table of const foldable functions, including in the case when it appears in a dwim form as in [+ 2 2] which is (dwim + 2 2). In this case, recursively check the arguments for constantp_noex. We get the hash table of foldable functions from the sys:%const-foldable% variable, which comes from an autoloaded module. (constantp): Fully expand the input form, not just m macroexpand. (eval_init): Register the const_foldable_s variable. * lisplib.c (constfun_instantiate, constfun_set_entries): New static functions. (lisplib_init): Register auto-loading of constfun module via new static functions. * stdlib/compiler.tl; Load the constfun module if %const-foldable% is not defined. (%const-foldable-funs%, %const-foldable%): Removed from here. * stdlib/constfun.tl: New file. (%const-foldable-funs%, %const-foldable%): Moved here. * txr.1: Documented changes to constantp.
