glsl: Refactor #version validation to be more future-proof.
The previous implementation required a flag in _mesa_glsl_parse_state
and line of code to initialize it for every version of the shading
language we intend to support. As we look to add 150, 330, 400, 410,
420, and beyond, this gets rather unwieldy.
This patch retains the switch statement (to reject, say, #version 111),
but removes all the bits. Code to check for ctx->API == API_OPENGL_CORE
could easily be added to the 110 and 120 cases to reject those.
v2: Use _mesa_is_desktop_gl to preserve the existing behavior in the
presence of the new API_OPENGL_CORE enumeration.

glsl: Generate IR for switch statements
Up until now modifying the GLSL compiler has been pretty straightforward.
This is where things get interesting. But still pretty straightforward.
Switch statements can be thought of a series of if/then/else statements.
Case labels are compared with the value of a test expression and the case
statements are executed if the comparison is true.
There are a couple of aspects of switch statements that complicate this simple
view of the world. The primary one is that cases can fall through sequentially
to subsequent case, unless a break statement is encountered, in which case,
the switch statement exits completely.
But break handling is further complicated by the fact that a break statement
can impact the exit of a loop. Thus, we need to coordinate break processing
between switch statements and loop statements.
The code generated by a switch statement maintains three temporary state
variables:
int test_value;
bool is_fallthru;
bool is_break;
test_value is initialized to the value of the test expression at the head of
the switch statement. This is the value that case labels are compared against.
is_fallthru is used to sequentially fall through to subsequent cases and is
initialized to false. When a case label matches the test expression, this
state variable is set to true. It will also be forced to false if a break
statement has been encountered. This forcing to false on break MUST be
after every case test. In practice, we defer that forcing to immediately after
the last case comparison prior to executing a case statement, but that is
an optimization.
is_break is used to indicate that a break statement has been executed and is
initialized to false. When a break statement is encountered, it is set to true.
This state variable is then used to conditionally force is_fallthru to to false
to prevent subsequent case statements from executing.
Code generation for break statements depends on whether the break statement is
inside a switch statement or inside a loop statement. If it inside a loop
statement is inside a break statement, the same code as before gets generated.
But if a switch statement is inside a loop statement, code is emitted to set
the is_break state to true.
Just as ASTs for loop statements are managed in a stack-like
manner to handle nesting, we also add a bool to capture the innermost switch
or loop condition. Note that we still need to maintain a loop AST stack to
properly handle for-loop code generation on a continue statement. Technically,
we don't (yet) need a switch AST stack, but I am using one for orthogonality
with loop statements, in anticipation of future use. Note that a simple
boolean stack would have sufficed.
We will illustrate a switch statement with its analogous conditional code that
a switch statement corresponds to by examining an example.
Consider the following switch statement:
switch (42) {
case 0:
case 1:
gl_FragColor = vec4(1.0, 2.0, 3.0, 4.0);
case 2:
case 3:
gl_FragColor = vec4(4.0, 3.0, 2.0, 1.0);
break;
case 4:
default:
gl_FragColor = vec4(0.0, 0.0, 0.0, 0.0);
}
Note that case 0 and case 1 fall through to cases 2 and 3 if they occur.
Note that case 4 and the default case must be reached explicitly, since cases
2 and 3 break at the end of their case.
Finally, note that case 4 and the default case don't break but simply fall
through to the end of the switch.
For this code, the equivalent code can be expressed as:
int test_val = 42; // capture value of test expression
bool is_fallthru = false; // prevent initial fall through
bool is_break = false; // capture the execution of a break stmt
is_fallthru |= (test_val == 0); // enable fallthru on case 0
is_fallthru |= (test_val == 1); // enable fallthru on case 1
is_fallthru &= !is_break; // inhibit fallthru on previous break
if (is_fallthru) {
gl_FragColor = vec4(1.0, 2.0, 3.0, 4.0);
}
is_fallthru |= (test_val == 2); // enable fallthru on case 2
is_fallthru |= (test_val == 3); // enable fallthru on case 3
is_fallthru &= !is_break; // inhibit fallthru on previous break
if (is_fallthru) {
gl_FragColor = vec4(4.0, 3.0, 2.0, 1.0);
is_break = true; // inhibit all subsequent fallthru for break
}
is_fallthru |= (test_val == 4); // enable fallthru on case 4
is_fallthru = true; // enable fallthru for default case
is_fallthru &= !is_break; // inhibit fallthru on previous break
if (is_fallthru) {
gl_FragColor = vec4(0.0, 0.0, 0.0, 0.0);
}
The code generate for |= and &= uses the conditional assignment capabilities
of the IR.

glsl: Reference data structure ctors in grammar
We now tie the grammar to the ctors of the ASTs they reference.
This requires that we actually have definitions of the ctors.
In addition, we also need to define "print" and "hir" methods for the AST
classes. The Print methods are pretty simple to flesh out. However, at this
stage of the development, we simply stub out the "hir" methods and flesh
them out later.
Also, since actual class instances get returned by the productions in the
grammar, we also need to designate the type of the productions that
reference those instances.

Very simple shaders don't actually use GLSL built-ins. For example:
- gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
- gl_FragColor = vec4(0.0);
Both of the shaders used by _mesa_meta_glsl_Clear() also qualify.
By waiting to initialize the built-ins until the first time we need to
look for a signature, we can avoid the overhead entirely in these cases.

glsl: Rewrote _mesa_glsl_process_extension to use table-driven logic.
Instead of using a chain of manually maintained if/else blocks to
handle "#extension" directives, we now consult a table that specifies,
for each extension, the circumstances under which it is available, and
what flags in _mesa_glsl_parse_state need to be set in order to
activate it.
This makes it easier to add new GLSL extensions in the future, and
fixes the following bugs:
- Previously, _mesa_glsl_process_extension would sometimes set the
"_enable" and "_warn" flags for an extension before checking whether
the extension was supported by the driver; as a result, specifying
"enable" behavior for an unsupported extension would sometimes cause
front-end support for that extension to be switched on in spite of
the fact that back-end support was not available, leading to strange
failures, such as those in
https://bugs.freedesktop.org/show_bug.cgi?id=38015.
- "#extension all: warn" and "#extension all: disable" had no effect.
Notes:
- All extensions are currently marked as unavailable in geometry
shaders. This should not have any adverse effects since geometry
shaders aren't supported yet. When we return to working on geometry
shader support, we'll need to update the table for those extensions
that are available in geometry shaders.
- Previous to this commit, if a shader mentioned
ARB_shader_texture_lod, extension ARB_texture_rectangle would be
automatically turned on in order to ensure that the types
sampler2DRect and sampler2DRectShadow would be defined. This was
unnecessary, because (a) ARB_shader_texture_lod works perfectly well
without those types provided that the builtin functions that
reference them are not called, and (b) ARB_texture_rectangle is
enabled by default in non-ES contexts anyway. I eliminated this
unnecessary behavior in order to make the behavior of all extensions
consistent.
NOTE: This is a candidate for the 7.10 and 7.11 branches.

glsl: Add a new opt_copy_propagation variant that does it channel-wise.
This patch cleans up many of the extra copies in GLSL IR introduced by
i965's scalarizing passes. It doesn't result in a statistically
significant performance difference on nexuiz high settings (n=3) or my
demo (n=10), due to brw_fs.cpp's register coalescing covering most of
those extra moves anyway. However, it does make the debug of wine's
GLSL shaders much more tractable, and reduces instruction count of
glsl-fs-convolution-2 from 376 to 288.

glsl: Fix memory error when creating the supported version string.
Passing ralloc_vasprintf_append a 0-byte allocation doesn't work. If
passed a non-NULL argument, ralloc calls strlen to find the end of the
string. Since there's no terminating '\0', it runs off the end.
Fixes a crash introduced in 14880a510a1a288df0778395097d5a52806abfb0.

glsl: Reject shader versions not supported by the implementation
Previously we'd happily compile GLSL 1.30 shaders on any driver. We'd
also happily compile GLSL 1.10 and 1.20 shaders in an ES2 context.
This has been a long standing FINISHME in the compiler.
NOTE: This is a candidate for the 7.9 and 7.10 branches

glsl: add continue/break/return unification/elimination pass (v2)
Changes in v2:
- Base class renamed to ir_control_flow_visitor
- Tried to comply with coding style
This is a new pass that supersedes ir_if_return and "lowers" jumps
to if/else structures.
Currently it causes no regressions on softpipe and nv40, but I'm not sure
whether the piglit glsl tests are thorough enough, so consider this
experimental.
It can be asked to:
1. Pull jumps out of ifs where possible
2. Remove all "continue"s, replacing them with an "execute flag"
3. Replace all "break" with a single conditional one at the end of the loop
4. Replace all "return"s with a single return at the end of the function,
for the main function and/or other functions
This gives several great benefits:
1. All functions can be inlined after this pass
2. nv40 and other pre-DX10 chips without "continue" can be supported
3. nv30 and other pre-DX10 chips with no control flow at all are better supported
Note that for full effect we should also teach the unroller to unroll
loops with a fixed maximum number of iterations but with the canonical
conditional "break" that this pass will insert if asked to.
Continues are lowered by adding a per-loop "execute flag", initialized to
TRUE, that when cleared inhibits all execution until the end of the loop.
Breaks are lowered to continues, plus setting a "break flag" that is checked
at the end of the loop, and trigger the unique "break".
Returns are lowered to breaks/continues, plus adding a "return flag" that
causes loops to break again out of their enclosing loops until all the
loops are exited: then the "execute flag" logic will ignore everything
until the end of the function.
Note that "continue" and "return" can also be implemented by adding
a dummy loop and using break.
However, this is bad for hardware with limited nesting depth, and
prevents further optimization, and thus is not currently performed.

glsl: Set default language version in mesa_glsl_parse_state constructor.
This should make it easier to change the default version based on the
API (say, version 1.00 for OpenGL ES).
Also, synchronize the symbol table's version with the parse state's
version just before doing AST-to-HIR. This way, it will be set when
it matters, but the main initialization code doesn't have to care about
the symbol table.
