Subject: clover: Dynamically calculate __OPENCL_VERSION__ and CLC language version
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c95d953b18d5174153e55957fb6947b9b59588ce;p=mesa.git

clover: Dynamically calculate __OPENCL_VERSION__ and CLC language version

Use get_language_version to calculate default cl standard based on
device capabilities and -cl-std specified in build options.

v5; move dev_clc_version declaration from an earlier patch
v4: Squash the __OPENCL_VERSION__ and CLC language version patches
v3: (Jan) Allow device_version up to 2.2 while device_clc_version
    only goes to 2.0
    Use get_cl_version to calculate version instead
v2: Split out from the previous patch (Pierre)
