Move compat/txm.c's top-level ranges verbatim into
compat/txm/{trust_cache,image4_aspace}.c and #include them from txm.c
in their original order; txm.c keeps only its includes. Cuts fall only
between top-level definitions; every part has balanced conditionals.
tools/test-txm-aspace-wide.py reads txm.c through read_source(), so its
mutants find their anchors and are written out as the whole unit. The
other readers (test-descriptor-stores, test-token-costs) already read
whole units since the sptm-user split.
Verification (base 84dd208 vs this commit):
- clang -c with the qualification flags (no -flto) and with
probes/run.py FLAGS, each plus -I shadow -I q1n1/platform/uefi:
compat/txm.c objects byte-identical (cmp). PASS
- Qualification flags with -flto: llvm-dis output identical and the
bitcode byte-identical. PASS
- probes/run.py build('xnuboot') with the qualification flags:
xnuboot.bin unchanged (sha256 0d8b9ec3...). PASS
- Reconstruction from the parts reproduces txm.c exactly.
- Host subset (50 commands: the standard battery and every test or
tool that names txm.c or builds the SPTM/TXM core), 300 s limit:
every outcome equal to base 84dd208. No new failure.
- wc -l: txm.c 9, parts 501 and 519 lines.
