# Fetch the upstream F32 disassembler used by the RLC/SDMA analysis, and apply our
# one-hunk fix. Not tracked: upstream work, no LICENSE file in the repo, and

# Pinned to the commit this analysis was done against. The patch makes
# out-of-range branch targets print as addresses instead of the string "True";
# see f32dis-loc.patch for why that matters.
