# usage: cc1_dumps.sh <draft.c> <tag> -> .run/c294/dumps_<tag>/<tag>.i.{rtl,jump,cse,loop,flow,combine,sched,lreg,greg} + <tag>.s
|

# gcc-2.7.2 cc1 writes dump files as <inputname>.<pass> in its CWD; we cd into a private dir so
|
|
# the repo root never collects gccdump.* droppings again.
|
|
# The draft must be self-contained (its own typedefs/externs); edit the cc1 line for -O0 (boot) modules.
|
|
# Prints: the .frame line (vars= is THE frame-residue oracle, §172/§501-M), the instruction count, the reload
|
|
# spill lines, and the ghost census (tools/ghost_census.py — the old standalone-`(use)` grep UNDER-COUNTS, §172 note).
