[Mesa-dev] [PATCH 13/15] gallium: add entry_point field to pipe_compute_state

[Karol Herbst]

for binaries containing multiple entry_points the driver can if this field is
set, optimize the binary in order to save memory.

For spir-v it can be used to compile against a specific entry_point. It is
guarenteed that the pc field can be ignored by the driver later if it decides
to do so.
