From 2c91e086563541271668f9ea6ca58689c0c97d44 Mon Sep 17 00:00:00 2001 From: Marta Lofstedt Date: Mon, 26 Oct 2015 11:22:27 +0100 Subject: mesa: Draw Indirect return wrong error code on unalinged From OpenGL 4.4 specification, section 10.4 and Open GL Es 3.1 section 10.5: "An INVALID_VALUE error is generated if indirect is not a multiple of the size, in basic machine units, of uint." However, the current code follow the ARB_draw_indirect: https://www.opengl.org/registry/specs/ARB/draw_indirect.txt "INVALID_OPERATION is generated by DrawArraysIndirect and DrawElementsIndirect if commands source data beyond the end of a buffer object or if is not word aligned." V2: After discussions on the list, it was suggested to only keep the INVALID_VALUE error.
