-15 is 0-7 twice times.Luminance Index 1 corresponds to (-12,-4, 4, 12);3. The 2-bit pixel index is 0, so the luminance supplement is-12. The color value of this pixel can be obtained (0-12, 34-12, 255-12), i.e. (0, 22, 243).The four mobile device GPUs support ETC1, so non-transparent textures on various Android devices can be in the ETC1 format, unfortunately ETC1 does not support transparency. For transparent textures, on Android devices, you can split RGB and alpha onto 2 ETC1 textures, which

example, for 4 (%esp,%eax,4) This operand, it represents the memory address is 4+%esp+4*%eax the value of the memory area.The operands are the majority of the instructions, so the above-mentioned methods, in the following articles we will often see, they will be a good friend of the ape friends.Article SummaryThis chapter only introduces some of the basics of the compilation, which is relatively not particularly difficult, but is the key to opening the door behind the mystery.
