pub fn set_list_code(p: usize, type_code: i32, cmplx: bool)Expand description
Patch a list-placeholder wordcode with its actual opcode +
jump distance. Direct port of zsh/Src/parse.c:738
set_list_code. zsh emits an ecadd(0) placeholder before
par_sublist runs, then comes back through set_list_code to
rewrite the slot with WCB_LIST(type, distance) once the
sublist’s final length is known.
Port of set_list_code(int p, int type, int cmplx) from
Src/parse.c:738. Patches the WCB_LIST header at p based on
whether the sublist body is simple (single command, no
pipeline) and Z_SYNC/Z_END — emits the Z_SIMPLE-optimized
header when possible, otherwise the plain WCB_LIST(type, 0).
