Subject: mesa: do not use a constant for MAX_COMPUTE_SHARED_SIZE
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=be27f77;p=mesa.git

mesa: do not use a constant for MAX_COMPUTE_SHARED_SIZE

This will allow to query the underlying drivers for the maximum
total storage size of all variables declared as <shared> with
PIPE_COMPUTE_CAP_MAX_LOCAL_SIZE.
