Previously, this was not really handled at all in
_mesa_ex3_error_check_format_and_type.  When the checks were tightened in
commit f15a7f3c, we accidentally tightened things too far and GL_BGRA_EXT
would always cause an error to be thrown.

There were two primary issues here.  First, is that
_mesa_es3_effective_internal_format_for_format_and_type didn't handle the
GL_BGRA_EXT format.  Second is that it blindly uses _mesa_base_tex_format
which returns GL_RGBA for GL_BGRA_EXT.  This commit fixes both of these
issues as well as adds explicit checks that GL_BGRA_EXT is only ever used
with GL_BGRA_EXT and GL_UNSIGNED_BYTE.

nouveau: make sure there's always room to emit a fence

I started seeing a lot of situations on nv30 where fence emission
wouldn't fit into the previous buffer (causing assertions). This ensures
that whenever checking for space, we always leave a bit of extra room
for the fence emission commands. Adjusts the nv30 and nvc0 fence
emission logic to bypass the space checking as well.

i965: Make vec4_visitor's destructor virtual

We need a virtual destructor when at least one of the class' methods is virtual.
Failure to do so might lead to undefined behavior when destructing derived classes.
Fixes the following warning:

brw_vec4_gs_visitor.cpp: In function 'const unsigned int* brw::brw_gs_emit(brw_context*, gl_shader_program*, brw_gs_compile*, void*, unsigned int*)':
brw_vec4_gs_visitor.cpp:703:11: warning: deleting object of polymorphic class type 'brw::vec4_gs_visitor' which has non-virtual destructor might cause undefined behaviour [-Wdelete-non-virtual-dtor]
    delete gs;

Curro: This shouldn't be causing any actual bugs at the moment because
gen6_gs_visitor is the only subclass of vec4_visitor destroyed through
a pointer of a base class (vec4_gs_visitor *) and its destructor is
basically the same as its parent's. Anyway it seems sensible to change
this so it doesn't bite us in the future.

9 years agonir: Introduce new nir_intrinsic_load_per_vertex_input intrinsics.
Kenneth Graunke [Thu, 1 Oct 2015 07:46:19 +0000 (00:46 -0700)]
nir: Introduce new nir_intrinsic_load_per_vertex_input intrinsics.

Geometry and tessellation shaders process multiple vertices; their
inputs are arrays indexed by the vertex number.  While GLSL makes
this look like a normal array, it can be very different behind the
scenes.

On Intel hardware, all inputs for a particular vertex are stored
together - as if they were grouped into a single struct.  This means
that consecutive elements of these top-level arrays are not contiguous.
In fact, they may sometimes be in completely disjoint memory segments.

NIR's existing load_input intrinsics are awkward for this case, as they
distill everything down to a single offset.  We'd much rather keep the
vertex ID separate, but build up an offset as normal beyond that.

This patch introduces new nir_intrinsic_load_per_vertex_input
intrinsics to handle this case.  They work like ordinary load_input
intrinsics, but have an extra source (src[0]) which represents the
outermost array index.

v2: Rebase on earlier refactors.
v3: Use ssa defs instead of nir_srcs, rebase on earlier refactors.

nir/lower_io: Make get_io_offset() return a nir_ssa_def * for indirects.

get_io_offset() already walks the dereference chain and discovers
whether or not we have an indirect; we can just return that rather than
computing it a second time via deref_has_indirect().  This means moving
the call a bit earlier.

By returning a nir_ssa_def *, we can pass back both an existence flag
(via NULL checking the pointer) and the value in one parameter.  It
also simplifies the code somewhat.  nir_lower_samplers works in a
similar fashion.
