[Mesa-dev] [PATCH 7/7] i965: Remove inst_info table from brw_eu_validate.

Francisco Jerez currojerez at riseup.net
Thu Apr 28 07:19:18 UTC 2016


At this point this doesn't contain any information not already in the
opcode_desc tables, the validation code can just call
brw_opcode_desc() in order to find out whether an instruction is
supported by the device.
