[PATCH v5 00/30] fpu: Export some internals for targets

Posted by Richard Henderson 4 days, 20 hours ago

Changes for v5:
  - Drop target/arm changes as non-essential;
    will be moved to another patch set.
  - Incorporate "Export floatN_minmax" from the FEAT_FP8 patch set.
  - Incorporate "fpu: Compress float_status", to avoid conflicts with...
  - Introduce float_status.e4m3_nan_is_snan
  - Fix NaN encoding for E4M3 in parts64_uncanon
