MSL does not support the unary "-" operator on matrix types. Similarly the SPIR-V OpFNegate/OpSNegate operations only work on scalar and vector type. * An expression such as "-<mat>" is now transformed to "-1.0 * <mat>" when generating MSL. * The same expression now generates a component-wise negation in SPIR-V, matching what glslang outputs for GLSL. * A unary "+" is now treated as NOP for MSL, matching the SPIR-V backend. An expression such as "+<expr>" is now evaluated as "<expr>". * The shared/Negation.sksl has been moved to folding/ as much of its contents exercise constant-folding of comparison expressions. * The shared/UnaryPositiveNegative.sksl test has been extended to exercise scalar and matrix types. NOTE: The SPIR-V backend changes have caused a minor re-ordering of SSA IDs generated when writing out a prefix-expression. The affected gold files have been updated.
