This lets drivers override ir_to_mesa with their own codegen, or at
least have a native alternative.
|
|
These are passes that we expect all codegen to be happy with. The
other lowering passes for Mesa IR are moved to the Mesa IR generator.

All the current HW backends transform subtract to adding the negation,
so I haven't bothered peepholing it back out in Mesa IR. This allows
some subtract of subtract to get removed in ir_algebraic.

Whereas constant folding evaluates constant expressions at rvalue
nodes, constant propagation tracks constant components of vectors
across execution to replace (possibly swizzled) variable dereferences
with constant values, triggering possible constant folding or reduced
variable liveness.

This lets us handle arrays much better than trying to work backwards
from assembly.
Fixes fbo-drawbuffers-maxtargets on swrast (i965 needs loop unrolling)

Include mtypes.h for GLcontext symbol.

Include mtypes.h for GLcontext symbol.

Support for samplers in general is still incomplete -- anything in a
uniform struct will still be broken. But that doesn't appear to be
any different from master.

Fixes glean shaderAPI.

Fixes a failure in glean shaderAPI.

st_program.h
Remove p_shader_tokens.h
Include st_context.h for st_context symbol.
Include p_state.h for PIPE_MAX_SHADER_INPUTS symbol.
Remove unnecessary forward declarations.
st_cb_bitmap.c
st_cb_clear.c
Include p_shader_tokens.h now that st_program.h doesn't include it.

Fixes piglit test array_texture.

The correct for this is of course to do what comment says

st_mesa_to_tgsi.h
Replace tgsi_ureg.h with a forward declaration.
Include p_compiler.h for ubyte symbol.
st_program.c
Include tgsi_ureg.h directly.
|
|
Include mtypes.h for GLcontext, gl_buffer_index, and GLframebuffer
symbols.
Include p_compiler.h for boolean symbol.
Include st_context.h in st_cb_eglimage.c as it previously included
st_context.h indirectly through st_manager.h.

Fixes fd.o bug 29388
NOTE: this is a candidate for the 7.8 branch.

Fixes ir_to_mesa handling of unop_log, which used the weird ARB_vp LOG
opcode that doesn't do what we want. This also lets the multiplication
coefficients in there get constant-folded, possibly.
Fixes:
glsl-fs-log

Optimizations at compile time should generally be done with the goal
of reducing instruction count so that other work, particularly
linking, is less time-consuming if the shader is used multiple times.
However, function inlining increases instruction count for the inlined
function bodies without removing the original function body, since we
don't know if it will be used at link time or not.
Reduces the runtime of linking and executing a Yo Frankie fragment
shader from 0.9 seconds to 0.5 seconds (-45.9%, +/- 2.2%, n=5).

This can only happen along a malloc failure path, but check anyway.

Mixing stderr (_mesa_print_program, _mesa_print_instruction,
_mesa_print_alu) with stdout means that when writing both to a file,
there isn't a consistent ordering between the two.

While the Mesa IR dumping includes some corresponding GLSL IR for
correlating Mesa IR to GLSL IR, it doesn't completely express it.
This printing includes things like variable declarations and control
flow structure that is hard to read otherwise.

Add inclusion guard.
Add forward declaration.
