Subject: i965: Re-index SSA definitions before printing NIR code.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f4310cdbd08f20276237fbefa3eba406aa109636;p=mesa.git

i965: Re-index SSA definitions before printing NIR code.

This makes the SSA definitions use sequential numbers (0, 1, 2, ...)
instead of seemingly random ones.  There's not much point normally,
but it makes debug output much easier to read.
