Stack (1.0)

vendor/gcc (gcc-15, BASE-VER 16.2.0)
    → build/gcc (host + self-host)
    → bin/g16 (unified driver)
    → libexec/grok16/{g16-cc,g16-cxx,g16-ld-bfd}

Forge tools

Tool	Role
gcc_fetch	Clone upstream GCC
gcc_configure	Host configure
gcc_build	Host build + install
gcc_rebuild	Self-host with g16
linker_install	g16-ld wrapper + BFD backend

Unified driver

• g16 — discern C/C++/Python/ASM + delegate
• g++16 — symlink to g16
• Backends in libexec/grok16/ (not moved — cc1 paths stay valid)

Key paths

Var	Default
GROK16_ROOT	repo root
G16_PREFIX	install prefix (= root in dev)
GROK16_GCC_SRC	vendor/gcc
GROK16_GCC_BUILD	build/gcc
