Apologies, I haven't had time to follow this discussion very
well, but I
should note setting EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION=t
in the
environment may help suppress trampoline compilation.
According to the function `comp-trampoline-compile', the
EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION environment variable
does not prevent trampoline compilation, only the saving of the
output of said trampoline compilation to the file system.
I just checked, EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION is
already set to t anyway. Sean exported it from dh_elpa_test just
before Christmas (65a588ca).
As of now, from what I understood of what I read in the upstream
mailing list and the comp.el file, the only way to truly prevent
trampoline compilation of a primitive is to add it to the variable
`native-comp-never-optimize-functions'. I think it could also be
possible to prevent the trampoline compilation of *any* primitive
by setting `comp-enable-subr-trampolines' to nil.
Best,
Aymeric
