From ce9a86975fbefead7b510da848dc1c6cbda5b5ed Mon Sep 17 00:00:00 2001 From: Giovanni Mascellani Date: Mon, 25 Oct 2021 09:06:28 +0200 Subject: [PATCH] vkd3d-shader/hlsl: Return the shape of the left operand when appropriate. The assumption about the size of matrices is not correct: it is legitimate to compose a matrix 2x2 with a vector of length 4, in which case it appears that the result has the shape of the first (leftmost) operand. Even for matrices 1xN or Nx1, the result is not always a vector: in general it has the shape of the first operand again.
