Register implied expression reads in OpLoad/OpAccessChain.

9728f9c1b7 Use correct block-name / other-name aliasing rules. 
A block name cannot alias with any name in its own scope,
and it cannot alias with any other "global" name.

To solve this, we need to complicate the name cache updates a little bit
where we have a "primary" namespace and "secondary" namespace.

acae607703 Register implied expression reads in OpLoad/OpAccessChain. 
This is required to avoid relying on complex sub-expression elimination
in compilers, and generates cleaner code.

The problem case is if a complex expression is used in an access chain,
like:

Composite comp = buffer[texture(...)];
vec4 a = comp.a + comp.b + comp.c;

Before, we did not have common subexpression tracking for
OpLoad/OpAccessChain, so we easily ended up with code like:

vec4 a = buffer[texture(...)].a + buffer[texture(...)].b + buffer[texture(...)].c;

A good compiler will optimize this, but we should not rely on it, and
forcing texture(...) to a temporary also looks better.

The solution is to add a vector "implied_expression_reads", which works
similarly to expression_dependencies. We also need an extra mechanism in
to_expression which lets us skip expression read checking and do it
later. E.g. for expr -> access chain -> load, we should only trigger
a read of expr when using the loaded expression.

MSL: Force signedness of shader vertex attributes to match the host.
 2018-12-04 09:37:55 -05:00
Chip Davis
06d483459b MSL: Force signedness of shader vertex attributes to match the host. 
Based on a patch by Stefan Dösinger.

Metal cannot do signedness conversion on vertex attributes, and for good
reason. Putting a `uint4` into an `int4`, or a `char4` into a `uint4`,
would lose those values that are outside the range of the target type.
But putting a `uchar4` into a `short4` or an `int4`, or a `ushort4` into
an `int4`, should work. In that case, force the signedness in the shader
to match the declared type of the host.

Unfortunately, I don't really know how to automatically test this. This
remapping is done based on input parameters normally supplied by
MoltenVK. I'm not sure how we'd set this up for the command-line
`spirv-cross` tool.

816c1167ce Handle invariant decoration more robustly. 
Avoids certain cases of variance between translation units by forcing
every dependent expression of a store to be temporary.
Should avoid the major failure cases where invariance matters.

6d675ae6a2 Correct carry/borrow bit checks. 
Don't use `addsat()`/`subsat()`; that'll erroneously flag cases where
the sum is exactly the maximum integer value, or the difference is
exactly 0. Also, correct the condition for the `select()` function; it's
basically `mix()` with a boolean factor.

(What was I *thinking*?)
