mesa/glsl: delete previously linked shaders earlier when linking

2016-11-09T13:53:50+00:00

This moves the delete linked shaders call to
_mesa_clear_shader_program_data() which makes sure we delete them
before returning due to any validation problems.

It also reduces some code duplication.

From the OpenGL 4.5 Core spec:

   "If LinkProgram failed, any information about a previous link of
   that program object is lost. Thus, a failed link does not restore
   the old state of program.

   ...

   If one of these commands is called with a program for which
   LinkProgram failed, no error is generated unless otherwise noted.
   Implementations may return information on variables and interface
   blocks that would have been active had the program been linked
   successfully. In cases where the link failed because the program
   required too many resources, these commands may help applications
   determine why limits were exceeded."

Therefore it's expected that we shouldn't be able to query the
program that failed to link and retrieve information about a
previously successful link.

Before this change the linker was doing validation before freeing
the previously linked shaders and therefore could exit on failure
before they were freed.

This change also fixes an issue in compat profile where a program
with no shaders attached is expect to fall back to fixed function
but was instead trying to relink IR from a previous link.

glsl/mesa: remove unused namespace support from the symbol table

2016-10-27T18:11:47+00:00

Namespace support seems to have been unused for a very long time.

Previously the hash table entry was never removed and the symbol name
wasn't freed until the symbol table was destroyed.

In theory this could reduced the number of times we need to copy a string
as duplicate names are reused. However in practice there is likely only a
limited number of symbols that are the same and this is likely to cause
other less than optimal behaviour such as the hash_table continuously
growing.

Along with dropping namespace support this change removes entries from
the hash table as they become unused.

mesa/st: support lowering multi-planar YUV

Support multi-planar YUV for external EGLImage's (currently just in the
dma-buf import path) by lowering to multiple texture fetch's for each
plane and CSC in shader.

There was some discussion of alternative approaches for tracking the
additional UV or U/V planes:

glsl: add subpass image type (v2)

2016-09-16T05:16:31+00:00

SPIR-V/Vulkan have a special image type for input attachments
called the subpass type. It has different characteristics than
other images types.

The main one being it can only be an input image to fragment
shaders and loads from it are relative to the frag coord.

This adds support for it to the GLSL types. Unfortunately
we've run out of space in the sampler dim in types, so we
need to use another bit.
