M2compiler-V3/compiler/build.sh

#!/bin/sh
#
# Builds the V3 M2 compiler (step 1: minimal integer pipeline to QBE).
# Requires GNU Modula-2 (gm2 -fiso) and the Coco/R CR binary.
#
# Usage: ./build.sh   (from the compiler directory)
#
# All sources live in src/ (grammar, frames, FileIO, SymTab, QbeGen,
# generated scanner/parser/driver). Objects land in the cwd; the
# binary links to ./M2. Generated .ssa goes to gen_ssa/.
#
# Pipeline: src/M2.atg -> src/M2S/M2P/M2 (.mod)
#           -> gm2 -fiso -I src -> ./M2
#           -> ./M2 tests/foo.mod -> gen_ssa/FOO.ssa -> qbe -> cc
