# Makefile.cbm — Build system for pure C rewrite
#
# Usage:
#   make -f Makefile.cbm test           # Build + run all tests (ASan + UBSan)
#   make -f Makefile.cbm test-foundation # Foundation tests only (fast)
#   make -f Makefile.cbm test-tsan      # Thread sanitizer build
#   make -f Makefile.cbm cbm            # Production binary
#   make -f Makefile.cbm clean-c        # Remove build artifacts

# Compiler selection — override via: make CC=gcc CXX=g++
# macOS: cc (Apple Clang) — universal binary with ASan support
# Linux: gcc/g++ — system default with full sanitizer support
# CI scripts pass CC/CXX explicitly; don't rely on defaults here

# Target architecture (macOS): build.sh/test.sh export ARCHFLAGS="-arch <arch>"
# (see scripts/env.sh). Fold it into the compiler drivers with `override` so it
# reaches EVERY compile and link recipe — including the vendored objects below
# that use their own *_CFLAGS — and so it survives a command-line `CC=` override.
# ARCHFLAGS is empty on Linux/Windows and for native direct `make` invocations,
# leaving CC/CXX unchanged there.
#
# Minimum macOS version (Apple targets only). Without one, clang takes the
# minimum from the SDK it compiles against (LC_BUILD_VERSION minos), so a
# release built on a macos-15 runner would refuse to start on macOS 14. 14.0
# keeps every macOS that could run a release built on the macos-14 runner
# (retired 2026-11-02). A flag folded into the drivers like ARCHFLAGS, not an
# exported MACOSX_DEPLOYMENT_TARGET: it reaches every compile AND link on every
# build path (build.sh, test.sh, direct make) and is part of each command line.
# Detected from the compiler's target, not the host, so a cross compiler run
# on a Mac is left untouched.

# fixes the CAUSE (an unannotated object makes ld assume the worst for the whole
# link), this flag fixes the OUTCOME, and the composition gate proves it on the
# shipped artifact. ELF-only: Apple's ld rejects -z noexecstack outright and it
# is meaningless for PE, so it is gated rather than made "common".
#
# -z separate-code additionally keeps read-only DATA out of the executable
# segment. GNU ld enables it by default on x86-64 but NOT on aarch64, so the
# arm64 binaries emitted ONE R E PT_LOAD spanning the whole image: .rodata is
# correctly marked A (not AX), but the kernel applies SEGMENT permissions, so
# ~259 MB of tree-sitter parse tables was mapped executable at runtime while the
# amd64 build of the same source mapped them R only. That is a large ROP gadget
# surface for data that is never executed, and it is invisible to section flags.
#
# -z relro + -z now finish the same job on the OTHER writable-but-shouldn't-be
# region: the GOT. Both are free at runtime here (a static binary resolves
# everything at link time, so there is no lazy binding left to pay for), and
# they are added because the SHIPPED artifact measurably lacked the property --
# not because the linker accepts the flags. Measured on this binary, built the
# way .github/workflows/_build.yml builds the Linux release (STATIC=1, gcc 13.3
# / GNU ld 2.42, Ubuntu 24.04 aarch64); PT_GNU_RELRO ends at 0x11DA0000 in both:
#
#   without -z now:  .got 0x11d9ec20+0x13c8, .got.plt 0x11d9ffe8+0x40
#                    -> .got.plt ends at 0x11DA0028, i.e. 40 bytes PAST the
#                       window: those GOT slots stayed writable for the whole
#                       process lifetime, in every Linux binary we have shipped
#   with    -z now:  .got.plt folded into .got (0x11d9ec20+0x13c8, ends
#                    0x11D9FFE8) -> the whole GOT is inside the window and is
#                    re-mapped read-only after startup
#
# -z relro is already this toolchain's default and changes nothing here; it is
# named anyway so the property stops depending on one distro's spec file (the
# musl/portable and glibc-floor images are different toolchains, and a default
# is not a guarantee). A1c/A1d in scripts/ci/check-binary-composition.sh assert

# like production -- -O2, mimalloc, the real allocator routing -- plus the event
# layer and its observers, because waste measured under ASan's allocator would
# describe ASan. Frame pointers stay so the macOS observer can walk to the
# caller. On Linux this is also what finally LINKS the --wrap observation shim:
# its flags and source were defined here but never reached a link line, so the
# Linux profiler had been reporting nothing.
#
# Every object is built this way, VENDORED ones included (grammars, the
# tree-sitter runtime, SQLite, tre, lz4, zstd, the C++ preprocessor): waste in
# a vendored parser is waste in this program. mimalloc alone is left as it is --
# its reads and writes are the allocator's own bookkeeping, not program data.
#
# MEMWASTE_ACCESS=1 adds the access lane (reads and writes of every tracked
# block through the compiler's load/store callbacks; clang only). It builds at
# -O1 without vectorisation: at -O2 the callbacks describe the OPTIMISED program,
# and reads the optimiser removed would be reported as never read.
# MEMWASTE_PROFILE=1 adds clang's execution counters (-fprofile-instr-generate)
# for the CPU scaling lane (scripts/memwaste-scaling.py).
# Each flavour needs its own BUILD_DIR: vendored objects are not rebuilt when
# only the flavour changes.

# The libc wrappers (mem_override_libc.c) need --wrap on Linux and Windows;
# macOS defines the symbols instead. STATIC=1 (musl) is not a memwaste target.

# mimalloc (vendored, global allocator override)
#
# Override strategy is platform-specific:
#  * Unix (macOS/Linux): rely on static-link-order override — the prod mimalloc
#    object is linked first so its strong malloc/free symbols win. We do NOT
#    define MI_MALLOC_OVERRIDE here: that would compile alloc-override.c's
#    forwarding definitions (malloc/free/posix_memalign/...) which, on macOS's
#    two-level namespace, makes the binary's free == mi_free while system
#    libraries keep allocating via the system allocator — pointers crossing that
#    boundary hit "mimalloc: error: mi_free: invalid pointer". (Repro:
#    `codebase-memory-cli index <dir>` aborted on every run.)
#  * Windows (MinGW, static CRT): the link-order trick fails (#424's allocator
#    mismatch), so we define MI_MALLOC_OVERRIDE=1 to compile the static-CRT
#    override added in mimalloc 3.3.0 (the _MSC_VER / _ACRTIMP /
#    _CRT_HYBRIDPATCHABLE entry points) which take precedence over the static
#    CRT's malloc/free.
# Note: mimalloc's source gates the override body on MI_MALLOC_OVERRIDE (CMake
# derives it from the MI_OVERRIDE option); MI_OVERRIDE alone is not read by the
# source — it is kept here only as this project's prod/test marker.
MIMALLOC_SRC = vendored/mimalloc/src/static.c
# Linux belongs on this list too (#1360). The "Unix relies on static-link-order
# override" strategy described above never actually worked: mimalloc defines
# malloc/free ONLY when MI_MALLOC_OVERRIDE is set (it gates alloc-override.c),
# so with the define off there were no strong symbols for the link order to
# prefer. Measured on the shipped v0.9.1-rc.1 artifacts — linux-arm64 glibc AND
# musl-static both report 0/6 allocator-owned size classes, i.e. ordinary malloc
# was going to libc and every purge/reclaim option set in cbm_mem_init applied
# only to the bound sqlite/tree-sitter populations.
#
# The macOS objection does not transfer. That abort is specific to the two-level
# namespace, where this binary's free becomes mi_free while system libraries keep
# allocating from the system allocator, so a pointer crossing the boundary hits
# "mi_free: invalid pointer". ELF is a flat namespace: interposition is
# process-wide and all-or-nothing, which is the configuration mimalloc is
# normally deployed in. macOS therefore stays off, deliberately and permanently.
#
# TWO defines, switched together in ONE place so they cannot drift:
# MI_MALLOC_OVERRIDE reaches the mimalloc translation unit and turns the
# override on; CBM_MEM_GLOBAL_OVERRIDE reaches OUR sources and tells the startup
# audit what to expect. CBM_MEM_GLOBAL_OVERRIDE goes only into CFLAGS_PROD,
# because MIMALLOC_CFLAGS_TEST compiles mimalloc with -DMI_OVERRIDE=0 and no
# override define at all — a test binary has no global override BY CONSTRUCTION

# also compiles its constructor, so _mi_auto_process_init runs twice (that
# constructor plus the CRT TLS callback) and the second options flush writes a
# stray newline to stderr before main: a blank first line on every run, which

# assertions, fine-grained statistics, padding on every block and a memset of

# (macOS) and 444 GB (Linux, where mimalloc also serves libc's malloc) of byte
# work inside the allocator (2026-09-17). Committed-bytes accounting, which the
# memory budget reads, is kept in every build (subproc stats, not MI_STAT).
# The TEST build below keeps mimalloc's debug checks.
# MI_PROFILE=0: mimalloc 3.5.2+ compiles its allocation-sampling profiler in by
# default, which puts a sample countdown on the allocation path. The product
# never uses it, so the production allocator leaves it out (the contract in

# detect_invalid_pointer_pairs is deliberately NOT here. It fires during

# red lane reporting a non-defect, which teaches people to ignore the lane.
# The instrumentation it requires (-fsanitize=pointer-compare,pointer-
# subtract) comes out with it, since it is dead weight without the check.

# Gating variant: identical run, but vendored-tree diagnostics are excluded
# (analyzer diagnostics bypass --header-filter by design; this mirrors the
# .cppcheck vendored suppression) and any finding the gate cannot account for
# fails the target. A finding here is a leak path, null deref, or uninitialized
# read the analyzer can prove — triage it against the code.
#
# A finding is accounted for by being FIXED, or — only where the analyzer is
# genuinely wrong — by an argued entry in scripts/lint-mem-whitelist.txt. Each
# entry is pinned to the sha256 of the function it argues about, so editing
# that function invalidates it and the finding must be argued again against
# the new code. A suppression is never allowed to outlive its reasoning, and
# NOLINT is never honoured here.
