52c76dbad3 glsl: use without_array() rather than get_scalar_type()
Here get_scalar_type() was just being use to remove the array
after that we converted it back to base_type anyway so just
use the without_array() helper.

f81ede4699 glsl: builtin: always return clones of the builtins
Builtins are created once and allocated using their own private ralloc
context. When reparenting IR that includes builtins, we might be steal
bits of builtins. This is problematic because these builtins might now
be freed when the shader that includes then last is disposed. This
might also lead to inconsistent ralloc trees/lists if shaders are
created on multiple threads.

Rather than including builtins directly into a shader's IR, we should
include clones of them in the ralloc context of the shader that
requires them. This fixes double free issues we've been seeing when
running shader-db on a big multicore (72 threads) server.

v2: Also rename _mesa_glsl_find_builtin_function_by_name() to better
    reflect how this function is used. (Ken)

9fc86d4f53 glsl: fix subroutine mismatch between declarations/definitions
Previously, when q.subroutine was set to 1, a new subroutine
declaration was added to the AST, while 0 meant a subroutine
definition has been detected by the parser.

Thus, setting the q.subroutine flag in both situations is
obviously wrong because a new type identifier is added instead
of trying to match the declaration. To fix it up, introduce
ast_type_qualifier::is_subroutine_decl() to differentiate
declarations and definitions easily.

This fixes a regression with:
arb_shader_subroutine/compiler/direct-call.vert

87ee1729d0 glsl: use an enum for AMD_conservative_depth layout qualifiers
The main idea behind this is to free some bits in the flags.q
struct because currently all 64-bits are used and we can't
add more layout qualifiers without reaching a static assert.

In order to do that (mainly for ARB_bindless_texture), use an
enumeration for the AMD_conservative_depth layout qualifiers
because it's forbidden to declare more than one depth qualifier
for gl_FragDepth.

Note that ast_type_qualifier::merge_qualifier() will prevent
using duplicate layout qualifiers by returning a compile-time
error.

No piglit regressions found (including compiler tests) with
RX480 on RadeonSI.

a73a618933 glsl: fix heap-use-after-free in ast_declarator_list::hir()
The get_variable_being_redeclared() function can free 'var' because

we set the array type to the 'earlier' declaration and free 'var' as it is

5bc222ebaf glsl: non-last member unsized array on SSBO must fail compilation on GLSL ES 3.1
From GLSL ES 3.10 spec, section 4.1.9 "Arrays":

"If an array is declared as the last member of a shader storage block
 and the size is not specified at compile-time, it is sized at run-time.
 In all other cases, arrays are sized only at compile-time."

In desktop GLSL it is allowed to have unsized-arrays that are
not last, as long as we can determine that they are implicitly
sized, which is detected at link-time.

the following shader:

We can also find:

From page 37 (page 43 of the PDF) of the GLSL 1.30 spec:

    " Initially, by default, all output variables are allowed to be
      variant. To force all output variables to be invariant, use the

      use this pragma in a fragment shader."

In do_assignment, we realized we needed an rvalue for (1 = 1), and
generated a temporary variable and assignment from the RHS.  We've
already flagged an error (non-lvalue in assignment), and return a bogus
value as the rvalue.  But process_array_size sees the bogus value, which
happened to be a constant expression, and rightly assumes that
processing a constant expression shouldn't have generated any code.

173558445d glsl: Size TCS->TES unsized arrays to gl_MaxPatchVertices for queries.
SSO validation and other program interface queries want to see that
unsized (non-patch) TCS output/TES input arrays are implicitly sized
to gl_MaxPatchVertices.

By the time we create the program resource lists, we've sized the arrays
to their actual size.  (We try to create TCS output arrays to match the
output patch size right away, and at this point, we should have shrunk
TES input arrays.)  One option would be to keep them sized to
gl_MaxPatchVertices, and defer shrinking them.  But that's a big change,
and I don't think it's a good idea.

Instead, this patch introduces a new ir_variable flag which indicates
the variable is implicitly to gl_MaxPatchVertices.  Then, the linker
munges the types when creating the resource list, ignoring the size
in the IR's types.  Basically, lie about it for resource queries.
It's ugly, but I think it ought to work.

We probably could use var->data.implicit_sized_array for this, but
I opted for a separate bit to try and avoid convoluting the existing
SSBO handling.  They're similar in concept, but share none of the
same code...

d0cd504046 glsl: Fix locations of variables in patch qualified interface blocks.
As of commit d82f8d9772, we actually
parse and attempt to handle the 'patch' qualifier on interface blocks.

This patch fixes explicit locations for variables in such blocks.
Without it, many program interface query dEQP/CTS tests hit this
assertion in ir_set_program_inouts.cpp

   if (is_patch_generic) {
      assert(idx >= VARYING_SLOT_PATCH0 && idx < VARYING_SLOT_TESS_MAX);
      bitfield = BITFIELD64_BIT(idx - VARYING_SLOT_PATCH0);
   }

because the location was incorrectly based on VARYING_SLOT_VAR0.

Note that most of the tests affected currently fail before they hit
this, due to confusion about what the program interface query name
of those resources should be.

72b56e8b1a glsl: Reject TCS/TES input arrays not sized to gl_MaxPatchVertices.
We handled the unsized case, implicitly sizing arrays to the value
of gl_MaxPatchVertices.  But if a size was present, we failed to
raise a compile error if it wasn't the value of gl_MaxPatchVertices.

Fixes CTS tests:

  *.tessellation_shader.compilation_and_linking_errors.
  {tc,te}_invalid_array_size_used_for_input_blocks

Piglit's tcs-input-read-nonconst-* tests have recently been fixed.
This patch will break older copies of those tests, but the latest
should continue working.  Update to Piglit 75819c13af2ed5.

19e929a177 glsl: Handle the inout qualifier in fragment shader output declarations.
According to the EXT_shader_framebuffer_fetch extension the inout
qualifier can be used on ESSL 3.0+ shaders to declare a special kind
of fragment output that gets implicitly initialized with the previous
framebuffer contents at the current fragment coordinates.  In addition
we allow using the same language to define FB fetch outputs in GLSL
1.3+ shaders in preparation for the desktop MESA_shader_framebuffer_fetch
extensions.

a32c87f74b glsl: emit a specific error when ast_*_assign changes type
For regular ast_add, we can implicitly change either a or b's type.
However in an assignment situation, the type of the lvalue is fixed. So
if the implicit conversion logic decides to change it, it means that the
rhs's type could not be converted to the lhs type.

Emit a specific error for this rather than the rather mysterious "is not
an lvalue" error that results from having a i2f or other operation as
the lvalue.
