[Mesa-dev] [PATCH 1/3] gallium: add PIPE_CAP_TGSI_CAN_READ_OUTPUTS
Nicolai Hähnle
nhaehnle at gmail.com
Tue Nov 29 11:01:45 UTC 2016
From: Nicolai Hähnle <nicolai.haehnle at amd.com>
Drivers that support this benefit by saving one lowering pass in the
GLSL-to-TGSI conversion.
radeonsi already supports this because all outputs are stored in temporary
variables before the export (except for TCS outputs, which have always
been readable in TGSI anyway due to their special semantics).

Components may overlap, notably when the gaps in an array of dvec3 are
