Subject: aarch64: Rename REG_TYPE_ZA* to REG_TYPE_ZAT*
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fd855fbb378e466fe8976b65743704da1136fe6e;p=binutils-gdb.git

aarch64: Rename REG_TYPE_ZA* to REG_TYPE_ZAT*

The ZA tile registers were called REG_TYPE_ZA, REG_TYPE_ZAH and
REG_TYPE_ZAV.  However, a later patch wants to make plain "za"
a register type too, and REG_TYPE_ZA is the obvious name for that.

This patch therefore adds "T" (tile) to the existing names.
