| * Faster, more compact, and readable closure creationMattias Engdegård2021-02-211-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify closure creation by calling a single function at run time instead of putting it together from small pieces. This is faster (by about a factor 2), takes less space on disk and in memory, and makes internal functions somewhat readable in disassembly listings again. This is done by creating a prototype function at compile-time whose closure variables are placeholder values V0, V1... which can be seen in the disassembly. The prototype is then cloned at run time using the new make-closure function that replaces the placeholders with the actual closure variables. * lisp/emacs-lisp/bytecomp.el (byte-compile-make-closure): Generate call to make-closure from a prototype function. * src/alloc.c (Fmake_closure): New function. (syms_of_alloc): Defsubr it. * src/data.c (syms_of_data): Defsym byte-code-function-p.
| * * lisp/emacs-lisp/bytecomp.el: Don't warn for repeated _ argsStefan Monnier2021-02-191-1/+3
| | | | | | | | | | (byte-compile-check-lambda-list): Skip warnings of repeated arg for those that are declared as unused anyway.

| * * lisp/emacs-lisp/macroexp.el: Break cycle with bytecomp/byte-optStefan Monnier2021-02-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change in macroexp triggered a cyclic dependency error during eager macroexpansion when neither `bytecomp` nor `byte-opt` had been byte-compiled yet. This fixes it by moving the offending function to macroexp.el. * lisp/emacs-lisp/macroexp.el (macroexp--unfold-lambda): Move from byte-opt.el and rename.
