Subject: intel/tools: add binary output type to i965_asm
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=430823c96b1ab9c5e99fedbf06856a2a24d36d91;p=mesa.git

intel/tools: add binary output type to i965_asm

Add '-t,--type' command line option to specify the output type
which can be 'bin', 'c_literal' or 'hex'.
