Mirrors cgen.c §5130-5223 / cgfnparams: reg-spill, tagged-partial-fit, pure-stack. Pure-stack does not bump cursor (cstage semantics). Fixes 16B over-allocation on 7+ arg functions; bootstrap stays byte-identical. Slice/str at reg/stack straddle is deferred to task #11 (cgfnparams doesn't stitch them either); pre-scan stays symmetric until then.

# ---- bootstrap (phase 10) ----------------------------------------------
|
|
# Four-stage self-host: Cstage (these C tools) → ww1 → ww2 → ww3 → ww4
|
|
# with cmp ww2 == ww3 and cmp ww3 == ww4. Stage 1 is wwdump_ww (the
|
|
# ww-built frontend); stages 2/3/4 assemble with w6a_ww and link with
|
|
# w6l_ww — every tool below the driver is now in ww. The C `ww` driver
|
|
# still orchestrates the pipeline (porting it is the remaining phase-10
|
|
# work).
|
|
#
|
|
# Why a fourth stage? Stage 3 proves ww1 and ww2 (which differ in how
|
|
# they were built) emit the same machine code. Stage 4 proves ww3 is
|
|
# byte-stable when used as a compiler — i.e. the fixed point is truly
|
|
# fixed, not merely a coincidental two-stage equilibrium.
