This is analogous to glsl_type::int_type and all the others.
|
|
This is nice because printing type->base_type in GDB will now give you a
readable name instead of a number.

As of 1.20, variable names, function names, and structure type names all
share a single namespace, and should conflict with one another in the
same scope, or hide each other in nested scopes.
However, in 1.10, variables and functions can share the same name in the
same scope. Structure types, however, conflict with/hide both.
Fixes piglit tests redeclaration-06.vert, redeclaration-11.vert,
redeclaration-19.vert, and struct-05.vert.

The variable is used but only in the body of an assert.

Make glsl include only main/core.h from core mesa.

Because the static types talloc their names at dlopen time,
talloc_freeing the types at DRI driver screen teardown means that if
the screen gets brought back up again, the names will point at freed
memory. talloc_autofree_context() exists to do just what we want
here: Free memory referenced across the program's lifetime so that we
avoid noise in memory leak checkers.
Fixes: bug #29722 (assertion failure in unigine).

to GLSL spec (and Win7 ATI drivers do complain about that)

Previously some sampler types were duplicated in GLSL 1.30 and
GL_EXT_texture_array. This resulted in not being able to find the
built-in sampler functions when the extension was used. When the
built-in functions were compiled, they bound to the 1.30 version.
This caused a type mismatch when trying to find the function. It also
resulted in a confusing error message:
0:0(0): error: no matching function for call to `texture2DArray(sampler2DArray, vec3)'
0:0(0): error: candidates are: vec4 texture2DArray(sampler2DArray, vec3)
0:0(0): error: vec4 texture2DArray(sampler2DArray, vec3, float)

Otherwise, we end up losing structure names after compile time, and
dumping IR often ends up reporting some other mysterious string.

This is quite a large patch because breaking it into smaller pieces
would result in the tree being intermitently broken. The big changes
are:
* Add the ir_var_temporary variable mode
* Change the ir_variable constructor to take the mode as a
parameter and correctly specify the mode for all ir_varables.
* Change the linker to not cross validate ir_var_temporary
variables.
* Change the linker to pull all ir_var_temporary variables from
global scope into 'main'.

Since the types are singletons across the lifetime of the compiler,
repeatedly compiling a program with the same structure type defined
would drop a copy of the array on the floor per compile.
This is a bit tricky because the static GLSL types are not called with
the talloc-based new, so we have to use the global type context, which
may not be initialized yet.
|
|
We regularly do lookups on the field names of the structure to find
the types within the struct, so returning a structure type with bad
names will lead to lots of error types being found.

Fixes glsl-fs-uniform-array-1, glsl-vs-uniform-array-1, and the -2
tests on software.

All scalar, vector, and matrix constructors are generated in-line
during AST-to-HIR translation. There is no longer any need to
generate function versions of the constructors.
