Subject: target/alpha: Fix SWCR_MAP_UMZ
X-Git-Tag: v4.2.0~128^2~26
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=712e7c6112c0c7df719b943a0138785e02f383c1;p=mirror_qemu.git

target/alpha: Fix SWCR_MAP_UMZ

We were setting the wrong bit.  The fp_status.flush_to_zero
setting is overwritten by either the constant 1 or the value
of fpcr_flush_to_zero depending on bits within an fp insn.
