Subject: aubinator: Make the iterator store a pointer to structure descriptions.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b2c0c1d9a5c6b1dd55d4e06f504e1ce9fe823c32;p=mesa.git

aubinator: Make the iterator store a pointer to structure descriptions.

When the iterator encounters a structure field, it now looks up the
gen_group for that structure definition and saves a pointer to it.

This lets us drop a lot of ridiculous code in the caller, which looked
at item->value (<struct NAME dword>), strtok'd the structure name back
out, and looked it up itself.
