pub fn signature_epilogue(sig_base: u32) -> Vec<u32>Expand description
Emit the signature epilogue (no terminator): materialize sig_base into the
scratch base register, then sd each captured register to sig_base + 8*i.
sig_base is the guest VA the scratchpad (slot[0]) DataCap maps at; the
guest’s stores CoW the region’s pages, and the host reads the effective
bytes back as the run’s lossless register signature (vs the old lossy x10
fold).
