The value must be in the range from 0 to 15. 29* A *gpr_idx* value which is described below. 30 31 ==================================== ============================================= 32 Gpr_idx Value Syntax Description 33 ==================================== ============================================= 34 gpr_idx(*<operand list>*) Enable indexing for the specified *operands* 35 and disable it for the rest. 36 *Operand list* is a comma-separated list of 37 values which may include: 38 39 * SRC0 - enable *src0* indexing. 40 41 * SRC1 - enable *src1* indexing. 42 43 * SRC2 - enable *src2* indexing. 44 45 * DST - enable *dst* indexing. 46 47 Each of these values may be specified only 48 once. 49 50 *Operand list* may be empty; this syntax 51 disables indexing for all operands. 52 ==================================== ============================================= 53 54Examples: 55 56.. parsed-literal:: 57 58 s_set_gpr_idx_mode 0 59 s_set_gpr_idx_mode gpr_idx() // the same as above 60 61 s_set_gpr_idx_mode 15 62 s_set_gpr_idx_mode gpr_idx(DST,SRC0,SRC1,SRC2) // the same as above 63 s_set_gpr_idx_mode gpr_idx(SRC0,SRC1,SRC2,DST) // the same as above 64 65 s_set_gpr_idx_mode gpr_idx(DST,SRC1) 66
