[PATCH v2 00/34] target/arm: FEAT_AFP followups for FEAT_SME2

[Richard Henderson]

Hi Peter,

I know you've sent a PR with some of this, but I don't have a
complete tree against which to rebase.  So this is still

Based-on: 20250124162836.2332150-1-peter.maydell@linaro.org
("[PATCH 00/76] target/arm: Implement FEAT_AFP and FEAT_RPRES")

Up to patch 22 is unchanged; after patch 22 is all new.

Most of them simplify floatN_muladd to use float_muladd_negate_*.
Five of them (25, 26, 27, 31, 32) address functions missed in
your v1 patchset.

Patch 30 was easier to write with the reversion in patch 29 first.
Obviously I wouldn't think you'd apply as-is.
