Move compat/ans.c's top-level ranges verbatim into
compat/ans/{nvme_model,sptm_dma}.c and #include them from ans.c in
their original order. ans.c keeps its header comment, include, layout
assertions, the ANS_ORDER barrier and the NVMe register and status
macros. Cuts fall only between top-level definitions; every part has
balanced conditionals.
No tool reads ans.c as text: tools/test-nvme-async.py compiles and
preprocesses it, which follows the includes, and the tools that pin
monitor sources already hash every part (first commit of this series).
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/ans.c objects byte-identical (cmp). PASS
- Qualification flags with -flto: llvm-dis output equal; the full IR
differs only in 2 inline-asm !srcloc source-location cookies (the
ANS_ORDER barrier). PASS
- probes/run.py build('xnuboot') with the qualification flags:
xnuboot.bin unchanged (sha256 0d8b9ec3...). PASS
- tools/test-ans.c host harness (ASan/UBSan, -DANS_HOST) on both trees:
"402324 checks, 0 failures". PASS
- Reconstruction from the parts reproduces ans.c exactly.
- Host subset (23 commands, including test-nvme-async), 300 s limit:
every outcome equal to base 84dd208. No new failure.
- wc -l: ans.c 34, parts 472 and 508 lines.
