From: Eric Anholt Date: Tue, 3 May 2011 17:55:50 +0000 (-0700) Subject: i965: Create a shared enum for hardware and compiler-internal opcodes. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6034b9a5124475d300d0678bd2fb6160865fa972;p=mesa.git i965: Create a shared enum for hardware and compiler-internal opcodes. This should make gdbing more pleasant, and it might be used in sharing part of the codegen between the VS and FS backends. --- diff --git a/src/mesa/drivers/dri/i965/brw_defines.h b/src/mesa/drivers/dri/i965/brw_defines.h index 0a3027d04ad..fe5d29c4328 100644 --- a/src/mesa/drivers/dri/i965/brw_defines.h +++ b/src/mesa/drivers/dri/i965/brw_defines.h @@ -557,58 +557,88 @@ #define BRW_WE_ALL 1 /** @} */ -#define BRW_OPCODE_MOV 1 -#define BRW_OPCODE_SEL 2 -#define BRW_OPCODE_NOT 4 -#define BRW_OPCODE_AND 5 -#define BRW_OPCODE_OR 6 -#define BRW_OPCODE_XOR 7 -#define BRW_OPCODE_SHR 8 -#define BRW_OPCODE_SHL 9 -#define BRW_OPCODE_RSR 10 -#define BRW_OPCODE_RSL 11 -#define BRW_OPCODE_ASR 12 -#define BRW_OPCODE_CMP 16 -#define BRW_OPCODE_CMPN 17 -#define BRW_OPCODE_JMPI 32 -#define BRW_OPCODE_IF 34 -#define BRW_OPCODE_IFF 35 -#define BRW_OPCODE_ELSE 36 -#define BRW_OPCODE_ENDIF 37 -#define BRW_OPCODE_DO 38 -#define BRW_OPCODE_WHILE 39 -#define BRW_OPCODE_BREAK 40 -#define BRW_OPCODE_CONTINUE 41 -#define BRW_OPCODE_HALT 42 -#define BRW_OPCODE_MSAVE 44 -#define BRW_OPCODE_MRESTORE 45 -#define BRW_OPCODE_PUSH 46 -#define BRW_OPCODE_POP 47 -#define BRW_OPCODE_WAIT 48 -#define BRW_OPCODE_SEND 49 -#define BRW_OPCODE_SENDC 50 -#define BRW_OPCODE_MATH 56 -#define BRW_OPCODE_ADD 64 -#define BRW_OPCODE_MUL 65 -#define BRW_OPCODE_AVG 66 -#define BRW_OPCODE_FRC 67 -#define BRW_OPCODE_RNDU 68 -#define BRW_OPCODE_RNDD 69 -#define BRW_OPCODE_RNDE 70 -#define BRW_OPCODE_RNDZ 71 -#define BRW_OPCODE_MAC 72 -#define BRW_OPCODE_MACH 73 -#define BRW_OPCODE_LZD 74 -#define BRW_OPCODE_SAD2 80 -#define BRW_OPCODE_SADA2 81 -#define BRW_OPCODE_DP4 84 -#define BRW_OPCODE_DPH 85 -#define BRW_OPCODE_DP3 86 -#define BRW_OPCODE_DP2 87 -#define BRW_OPCODE_DPA2 88 -#define BRW_OPCODE_LINE 89 -#define BRW_OPCODE_PLN 90 -#define BRW_OPCODE_NOP 126 +enum opcode { + /* These are the actual hardware opcodes. */ + BRW_OPCODE_MOV = 1, + BRW_OPCODE_SEL = 2, + BRW_OPCODE_NOT = 4, + BRW_OPCODE_AND = 5, + BRW_OPCODE_OR = 6, + BRW_OPCODE_XOR = 7, + BRW_OPCODE_SHR = 8, + BRW_OPCODE_SHL = 9, + BRW_OPCODE_RSR = 10, + BRW_OPCODE_RSL = 11, + BRW_OPCODE_ASR = 12, + BRW_OPCODE_CMP = 16, + BRW_OPCODE_CMPN = 17, + BRW_OPCODE_JMPI = 32, + BRW_OPCODE_IF = 34, + BRW_OPCODE_IFF = 35, + BRW_OPCODE_ELSE = 36, + BRW_OPCODE_ENDIF = 37, + BRW_OPCODE_DO = 38, + BRW_OPCODE_WHILE = 39, + BRW_OPCODE_BREAK = 40, + BRW_OPCODE_CONTINUE = 41, + BRW_OPCODE_HALT = 42, + BRW_OPCODE_MSAVE = 44, + BRW_OPCODE_MRESTORE = 45, + BRW_OPCODE_PUSH = 46, + BRW_OPCODE_POP = 47, + BRW_OPCODE_WAIT = 48, + BRW_OPCODE_SEND = 49, + BRW_OPCODE_SENDC = 50, + BRW_OPCODE_MATH = 56, + BRW_OPCODE_ADD = 64, + BRW_OPCODE_MUL = 65, + BRW_OPCODE_AVG = 66, + BRW_OPCODE_FRC = 67, + BRW_OPCODE_RNDU = 68, + BRW_OPCODE_RNDD = 69, + BRW_OPCODE_RNDE = 70, + BRW_OPCODE_RNDZ = 71, + BRW_OPCODE_MAC = 72, + BRW_OPCODE_MACH = 73, + BRW_OPCODE_LZD = 74, + BRW_OPCODE_SAD2 = 80, + BRW_OPCODE_SADA2 = 81, + BRW_OPCODE_DP4 = 84, + BRW_OPCODE_DPH = 85, + BRW_OPCODE_DP3 = 86, + BRW_OPCODE_DP2 = 87, + BRW_OPCODE_DPA2 = 88, + BRW_OPCODE_LINE = 89, + BRW_OPCODE_PLN = 90, + BRW_OPCODE_NOP = 126, + + /* These are compiler backend opcodes that get translated into other + * instructions. + */ + FS_OPCODE_FB_WRITE = 128, + FS_OPCODE_RCP, + FS_OPCODE_RSQ, + FS_OPCODE_SQRT, + FS_OPCODE_EXP2, + FS_OPCODE_LOG2, + FS_OPCODE_POW, + FS_OPCODE_SIN, + FS_OPCODE_COS, + FS_OPCODE_DDX, + FS_OPCODE_DDY, + FS_OPCODE_PIXEL_X, + FS_OPCODE_PIXEL_Y, + FS_OPCODE_CINTERP, + FS_OPCODE_LINTERP, + FS_OPCODE_TEX, + FS_OPCODE_TXB, + FS_OPCODE_TXD, + FS_OPCODE_TXL, + FS_OPCODE_DISCARD, + FS_OPCODE_SPILL, + FS_OPCODE_UNSPILL, + FS_OPCODE_PULL_CONSTANT_LOAD, +};
