glsl: Modify strategy for accumulating conditions when lowering if-statements
Previously if-statements were lowered from inner-most to outer-most
(i.e., bottom-up). All assignments within an if-statement would have
the condition of the if-statement appended to its existing condition.
As a result the assignments from a deeply nested if-statement would
have a very long and complex condition.
Several shaders in the OpenGL ES2 conformance test suite contain
non-constant array indexing that has been lowered by the shader
writer. These tests usually look something like:
if (i == 0) {
value = array[0];
} else if (i == 1) {
value = array[1];
} else ...
The IR for the last assignment ends up as:
(assign (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@20) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@22) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@24) ) (var_ref if_to_cond_assign_condition@26) ) ) ) ) (x) (var_ref value) (array_ref (var_ref array) (constant int (5)))
The Mesa IR that is generated from this is just as awesome as you
might expect.
Three changes are made to the way if-statements are lowered.
1. Two condition variables, if_to_cond_assign_then and
if_to_cond_assign_else, are created for each if-then-else structure.
The former contains the "positive" condition, and the later contains
the "negative" condtion. This change was implemented in the previous
patch.
2. Each condition variable is added to a hash-table when it is created.
3. When lowering an if-statement, assignments to existing condtion
variables get the current condition anded. This ensures that nested
condition variables are only set to true when the condition variable
for all outer if-statements is also true.
Changes #1 and #3 combine to ensure the correctness of the resulting
code.
4. When a condition assignment is encountered with a condition that is
a dereference of a previously added condition variable, the condition
is not modified.
Change #4 prevents the continuous accumulation of conditions on
assignments.
If the original if-statements were:
if (x) {
if (a && b && c && d && e) {
...
} else {
...
}
} else {
if (g && h && i && j && k) {
...
} else {
...
}
}
The lowered code will be
if_to_cond_assign_then@1 = x;
if_to_cond_assign_then@2 = a && b && c && d && e
&& if_to_cond_assign_then@1;
...
if_to_cond_assign_else@2 = !if_to_cond_assign_then
&& if_to_cond_assign_then@1;
...
if_to_cond_assign_else@1 = !if_to_cond_assign_then@1;
if_to_cond_assign_then@3 = g && h && i && j;
&& if_to_cond_assign_else@1;
...
if_to_cond_assign_else@3 = !if_to_cond_assign_then
&& if_to_cond_assign_else@1;
...
Depending on how instructions are emitted, there may be an extra
instruction due to the duplication of the '&&
if_to_cond_assign_{then,else}@1' on the nested else conditions. In
addition, this may cause some unnecessary register pressure since in
the simple case (where the nested conditions are not complex) the
nested then-condition variables are live longer than strictly
necessary.
Before this change, one of the shaders in the OpenGL ES2 conformance
test suite's acos_float_frag_xvary generated 348 Mesa IR instructions.
After this change it only generates 124. Many, but not all, of these
instructions would have also been eliminated by CSE.

At least one of the invariants verified by IR validation concerns the

global variables must come after the declarations of those global
variables.
Since linking affects the ordering of toplevel constructs in the IR,
it's possible that a bug in the linker will cause invalid IR to be

such a bug was fixed by the previous commit.)
Bugs like this are easily masked by further optimization passes,
particularly inlining. So to make them easier to track down, this

final optimization occurs. The validation only occurs on debug

The ast-to-hir conversion needs to emit function signatures in two
circumstances: when a function declaration (or definition) is

To avoid emitting a function signature in an illegal place (such as
inside a function), emit_function() checked whether we were inside a
function definition, and if so, emitted the signature before the
function definition.
However, this didn't cover the case of emitting function signatures
for built-in functions when those built-in functions are called from
inside the constant integer expression that specifies the length of a
global array. This failed because when processing an array length, we
are emitting IR into a dummy exec_list (see process_array_type() in
ast_to_hir.cpp). process_array_type() later checks (via an assertion)
that no instructions were emitted to the dummy exec_list, based on the

Revert "glsl: Skip processing the first function's body in do_dead_functions()."
opt_dead_functions contained a shortcut to skip processing the first
function's body, based on the assumption that IR functions are
topologically sorted, with callees always coming before their callers
(therefore the first function cannot contain any calls).
This assumption turns out not to be true in general. For example, the
following code snippet gets translated to IR that violates this
assumption:
void f();
void g();
void f() { g(); }
void g() { ... }
In practice, the shortcut didn't cause bugs because of a coincidence
of the circumstances in which opt_dead_functions is called:
(a) we do inlining right before dead function elimination, and
inlining (when successful) eliminates all calls.
(b) for user-defined functions, inlining is always successful, because
previous optimization passes (during compilation) have reduced
them to a form that is eligible for inlining.
(c) the function that appears first in the IR can't possibly call a
built-in function, because built-in functions are always emitted
before the function that calls them.
It seems unnecessarily fragile to have opt_dead_functions depend on
these coincidences. And the next patch in this series will break (c).
So I'm reverting the shortcut. The consequence will be a slight
increase in link time for complex shaders.

validate_program relies on validate_shader_program to fill in errMsg;
empirically, there exist cases where that doesn't happen.
While tracking those down may be worthwhile, initializing the string so
we don't try to ralloc_strdup random garbage also seems wise.
Fixes issues caught by valgrind while running some test case.
NOTE: This is a candidate for stable release branches.
