/**
* This file contains macros for building command buffers in memory.

* Use NEW_CB for buffers with a varying size and it will also allocate
* the buffer.
* Use BEGIN_CB for arrays with a static size.
*
* Example:
*
* uint32_t cb[3];
* CB_LOCALS;
*
* BEGIN_CB(cb, 3);
* OUT_CB_REG_SEQ(R500_RB3D_CONSTANT_COLOR_AR, 2);
* OUT_CB(blend_color_red_alpha);
* OUT_CB(blend_color_green_blue);
* END_CB;
*
* And later:
*
* CS_LOCALS;
* WRITE_CS_TABLE(cb, 3);
*
* Or using a little slower variant:
*
* CS_LOCALS;
* BEGIN_CS(cb, 3);
* OUT_CS_TABLE(cb, 3);
* END_CS;
