Subject: anv: Don't re-upload shaders when merging
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=584f39c65ed24d6c331d8ccf05d93678f3fafe16;p=mesa.git

anv: Don't re-upload shaders when merging

Using anv_pipeline_cache_upload_kernel() will re-upload the kernel and
prog_data when we merge caches. Since the kernel and prog_data is
already in the program_stream, use anv_pipeline_cache_add_entry()
instead to only add the entry to the hash table.
