There was a problem hiding this comment.
Mostly good, see comments. I think we need the same for caml_curry functions to avoid explosion for them as well.

A
caml_applyfunction generated for atyp_valargument or result can also be used with a tagged immediate in the same argument or result position. At present, this fact is not exploited, meaning that we are generating many morecaml_applyfunctions than we should be.This patch uses a new
Extended_machtype.ttype which distinguishes tagged immediates, unlikeCmm.machtype. This is sufficient to make use of the above fact.More than 80% of the
caml_applyfunctions inocamlopt.optare removed by this scheme.Tested using Closure, Flambda 1 and Flambda 2.
Still needs porting to the
ocaml/subdirectory.
