When gl_Position is defined by SPIR-V, but neither used nor initialized, it appeared twice in the MSL output, as gl_Position and glPosition_1. The existing tests for whether an output is active check only that it is used by an op, or initialized. Adding the implicit gl_Position also marked the existing gl_Position as active, duplicating the output variable. Fix is that when checking for the need to add an implicit gl_Position output, also check if the var is already defined in the shader, and just needs to be marked as active. Add test shader. |
