# EDITING AND DEBUGGING THIS FILE MAY DAMAGE YOUR BRAIN SERIOUSLY.

# Uncomment the following line to get exhaustive debug output.

# m4_debugmode(aceflqtx)
|

#
|
||||
# How it works:
|
||||
# 1) Instruction to code conversion (uses diversions 100..199)
|
||||
# 2) Code wrapping (uses diversions 1..99)
|
||||
# 3) Final preparation (uses diversions 200..299)
|
||||
# 4) Shipout
|
||||
#
|
||||
# See below for detailed description.
|
||||
#
|
||||
#
|
||||
# 1) Instruction to code conversion
|
||||
# The code provided in f-inst.c between consecutive INST() calls
|
||||
# is interleaved for many different places. It is here processed
|
||||
# and split into separate instances where split-by-instruction
|
||||
# happens. These parts are stored in temporary diversions listed:
|
||||
#
|
||||
# Per-inst Diversions:
|
||||
# 101 content of per-inst struct
|
||||
# 102 constructor arguments
|
||||
# 103 constructor body
|
||||
# 104 dump line item content
|
||||
# (there may be nothing in dump-line content and
|
||||
# it must be handled specially in phase 2)
|
||||
# 105 linearize body
|
||||
# 106 comparator body
|
||||
# 107 struct f_line_item content
|
||||
# 108 interpreter body
|
||||
#
|
||||
# Final diversions
|
||||
# 200+ completed text before it is flushed to output
