Subject: r300: fix VP source conflict resolution on 64-bit machines
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e0fda040135490fdd54e57000c7995e27dc70657;p=mesa.git

r300: fix VP source conflict resolution on 64-bit machines

On 32bit machines we were lucky because the sizeof(reg) == sizeof(rc_src_register).
On 64bit machines pointers are 8 bytes long, so we were overwriting other data.
