Subject: mesa/format_info: Add support for compressed floating-point formats
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=84218b598f429bcc4474aa620da906b7b9aadc2b;p=mesa.git

mesa/format_info: Add support for compressed floating-point formats

If the name of a compressed texture format has ‘FLOAT’ in it it will now set
the data type of the format to GL_FLOAT. This will be needed for the BPTC
half-float formats.
