# Builds the TopSpeed-V3 sidecar front-end (TSM2) from
# compiler/src/TopSpeed-V3-M2.atg.
#
# The sidecar is a *grammar* deliverable: it parses the historical
# TopSpeed/JPI V3 dialect (pragmas, H/C/B literals, ::=, address
# constructors, CLASS/IS/VIRTUAL, manifest constants, tagless variant
# records, ...).  It reuses the V3 frontend frame (scanner/parser/
# compiler .frm) and the V3 SymTab/QbeGen/FileIO modules, so it tracks
# the V3 API -- a small drift patch is applied here if a call site has
# moved on (see the sed lines below).
#
# Output: build/TSM2  (build/ is git-ignored)
