From 999b995ddc4a8a2f146ebf9a46c9924c6a7c65a6 Mon Sep 17 00:00:00 2001 From: Stefan Kristiansson Date: Thu, 8 May 2014 08:53:09 +0300 Subject: or1k: add support for l.swa/l.lwa atomic instructions This adds support for the load-link/store-conditional l.lwa/l.swa atomic instructions. The support is added in such way, that the cpu description not only describes the mnemonics, but also the functionality. A couple of fixes to typos in nearby/related code are also snuck into this. cpu/ * or1korbis.cpu (h-atomic-reserve): New hardware. (h-atomic-address): Likewise. (insn-opcode): Add opcodes for LWA and SWA. (atomic-reserve): New operand. (atomic-address): Likewise. (l-lwa, l-swa): New instructions. (l-lbs): Fix typo in comment. (store-insn): Clear atomic reserve on store to atomic-address. Fix register names in fmt field. opcodes/ * or1k-desc.c: Regenerated. * or1k-desc.h: Likewise. * or1k-opc.c: Likewise. * or1k-opc.h: Likewise. * or1k-opinst.c: Likewise. --- opcodes/or1k-opc.h | 53 +++++++++++++++++++++++++++-------------------------- 1 file changed, 27 insertions(+), 26 deletions(-) (limited to 'opcodes/or1k-opc.h') diff --git a/opcodes/or1k-opc.h b/opcodes/or1k-opc.h index 3f878dc..e8b3de1 100644 --- a/opcodes/or1k-opc.h +++ b/opcodes/or1k-opc.h @@ -39,32 +39,33 @@ typedef enum cgen_insn_type { , OR1K_INSN_L_JALR, OR1K_INSN_L_BNF, OR1K_INSN_L_BF, OR1K_INSN_L_TRAP , OR1K_INSN_L_SYS, OR1K_INSN_L_RFE, OR1K_INSN_L_NOP_IMM, OR1K_INSN_L_NOP , OR1K_INSN_L_MOVHI, OR1K_INSN_L_MACRC, OR1K_INSN_L_MFSPR, OR1K_INSN_L_MTSPR - , OR1K_INSN_L_LWZ, OR1K_INSN_L_LWS, OR1K_INSN_L_LBZ, OR1K_INSN_L_LBS - , OR1K_INSN_L_LHZ, OR1K_INSN_L_LHS, OR1K_INSN_L_SW, OR1K_INSN_L_SB - , OR1K_INSN_L_SH, OR1K_INSN_L_SLL, OR1K_INSN_L_SLLI, OR1K_INSN_L_SRL - , OR1K_INSN_L_SRLI, OR1K_INSN_L_SRA, OR1K_INSN_L_SRAI, OR1K_INSN_L_ROR - , OR1K_INSN_L_RORI, OR1K_INSN_L_AND, OR1K_INSN_L_OR, OR1K_INSN_L_XOR - , OR1K_INSN_L_ADD, OR1K_INSN_L_SUB, OR1K_INSN_L_ADDC, OR1K_INSN_L_MUL - , OR1K_INSN_L_MULU, OR1K_INSN_L_DIV, OR1K_INSN_L_DIVU, OR1K_INSN_L_FF1 - , OR1K_INSN_L_FL1, OR1K_INSN_L_ANDI, OR1K_INSN_L_ORI, OR1K_INSN_L_XORI - , OR1K_INSN_L_ADDI, OR1K_INSN_L_ADDIC, OR1K_INSN_L_MULI, OR1K_INSN_L_EXTHS - , OR1K_INSN_L_EXTBS, OR1K_INSN_L_EXTHZ, OR1K_INSN_L_EXTBZ, OR1K_INSN_L_EXTWS - , OR1K_INSN_L_EXTWZ, OR1K_INSN_L_CMOV, OR1K_INSN_L_SFGTS, OR1K_INSN_L_SFGTSI - , OR1K_INSN_L_SFGTU, OR1K_INSN_L_SFGTUI, OR1K_INSN_L_SFGES, OR1K_INSN_L_SFGESI - , OR1K_INSN_L_SFGEU, OR1K_INSN_L_SFGEUI, OR1K_INSN_L_SFLTS, OR1K_INSN_L_SFLTSI - , OR1K_INSN_L_SFLTU, OR1K_INSN_L_SFLTUI, OR1K_INSN_L_SFLES, OR1K_INSN_L_SFLESI - , OR1K_INSN_L_SFLEU, OR1K_INSN_L_SFLEUI, OR1K_INSN_L_SFEQ, OR1K_INSN_L_SFEQI - , OR1K_INSN_L_SFNE, OR1K_INSN_L_SFNEI, OR1K_INSN_L_MAC, OR1K_INSN_L_MSB - , OR1K_INSN_L_MACI, OR1K_INSN_L_CUST1, OR1K_INSN_L_CUST2, OR1K_INSN_L_CUST3 - , OR1K_INSN_L_CUST4, OR1K_INSN_L_CUST5, OR1K_INSN_L_CUST6, OR1K_INSN_L_CUST7 - , OR1K_INSN_L_CUST8, OR1K_INSN_LF_ADD_S, OR1K_INSN_LF_ADD_D, OR1K_INSN_LF_SUB_S - , OR1K_INSN_LF_SUB_D, OR1K_INSN_LF_MUL_S, OR1K_INSN_LF_MUL_D, OR1K_INSN_LF_DIV_S - , OR1K_INSN_LF_DIV_D, OR1K_INSN_LF_REM_S, OR1K_INSN_LF_REM_D, OR1K_INSN_LF_ITOF_S - , OR1K_INSN_LF_ITOF_D, OR1K_INSN_LF_FTOI_S, OR1K_INSN_LF_FTOI_D, OR1K_INSN_LF_EQ_S - , OR1K_INSN_LF_EQ_D, OR1K_INSN_LF_NE_S, OR1K_INSN_LF_NE_D, OR1K_INSN_LF_GE_S - , OR1K_INSN_LF_GE_D, OR1K_INSN_LF_GT_S, OR1K_INSN_LF_GT_D, OR1K_INSN_LF_LT_S - , OR1K_INSN_LF_LT_D, OR1K_INSN_LF_LE_S, OR1K_INSN_LF_LE_D, OR1K_INSN_LF_MADD_S - , OR1K_INSN_LF_MADD_D, OR1K_INSN_LF_CUST1_S, OR1K_INSN_LF_CUST1_D + , OR1K_INSN_L_LWZ, OR1K_INSN_L_LWS, OR1K_INSN_L_LWA, OR1K_INSN_L_LBZ + , OR1K_INSN_L_LBS, OR1K_INSN_L_LHZ, OR1K_INSN_L_LHS, OR1K_INSN_L_SW + , OR1K_INSN_L_SB, OR1K_INSN_L_SH, OR1K_INSN_L_SWA, OR1K_INSN_L_SLL + , OR1K_INSN_L_SLLI, OR1K_INSN_L_SRL, OR1K_INSN_L_SRLI, OR1K_INSN_L_SRA + , OR1K_INSN_L_SRAI, OR1K_INSN_L_ROR, OR1K_INSN_L_RORI, OR1K_INSN_L_AND + , OR1K_INSN_L_OR, OR1K_INSN_L_XOR, OR1K_INSN_L_ADD, OR1K_INSN_L_SUB + , OR1K_INSN_L_ADDC, OR1K_INSN_L_MUL, OR1K_INSN_L_MULU, OR1K_INSN_L_DIV + , OR1K_INSN_L_DIVU, OR1K_INSN_L_FF1, OR1K_INSN_L_FL1, OR1K_INSN_L_ANDI + , OR1K_INSN_L_ORI, OR1K_INSN_L_XORI, OR1K_INSN_L_ADDI, OR1K_INSN_L_ADDIC + , OR1K_INSN_L_MULI, OR1K_INSN_L_EXTHS, OR1K_INSN_L_EXTBS, OR1K_INSN_L_EXTHZ + , OR1K_INSN_L_EXTBZ, OR1K_INSN_L_EXTWS, OR1K_INSN_L_EXTWZ, OR1K_INSN_L_CMOV + , OR1K_INSN_L_SFGTS, OR1K_INSN_L_SFGTSI, OR1K_INSN_L_SFGTU, OR1K_INSN_L_SFGTUI + , OR1K_INSN_L_SFGES, OR1K_INSN_L_SFGESI, OR1K_INSN_L_SFGEU, OR1K_INSN_L_SFGEUI + , OR1K_INSN_L_SFLTS, OR1K_INSN_L_SFLTSI, OR1K_INSN_L_SFLTU, OR1K_INSN_L_SFLTUI + , OR1K_INSN_L_SFLES, OR1K_INSN_L_SFLESI, OR1K_INSN_L_SFLEU, OR1K_INSN_L_SFLEUI + , OR1K_INSN_L_SFEQ, OR1K_INSN_L_SFEQI, OR1K_INSN_L_SFNE, OR1K_INSN_L_SFNEI + , OR1K_INSN_L_MAC, OR1K_INSN_L_MSB, OR1K_INSN_L_MACI, OR1K_INSN_L_CUST1 + , OR1K_INSN_L_CUST2, OR1K_INSN_L_CUST3, OR1K_INSN_L_CUST4, OR1K_INSN_L_CUST5 + , OR1K_INSN_L_CUST6, OR1K_INSN_L_CUST7, OR1K_INSN_L_CUST8, OR1K_INSN_LF_ADD_S + , OR1K_INSN_LF_ADD_D, OR1K_INSN_LF_SUB_S, OR1K_INSN_LF_SUB_D, OR1K_INSN_LF_MUL_S + , OR1K_INSN_LF_MUL_D, OR1K_INSN_LF_DIV_S, OR1K_INSN_LF_DIV_D, OR1K_INSN_LF_REM_S + , OR1K_INSN_LF_REM_D, OR1K_INSN_LF_ITOF_S, OR1K_INSN_LF_ITOF_D, OR1K_INSN_LF_FTOI_S + , OR1K_INSN_LF_FTOI_D, OR1K_INSN_LF_EQ_S, OR1K_INSN_LF_EQ_D, OR1K_INSN_LF_NE_S + , OR1K_INSN_LF_NE_D, OR1K_INSN_LF_GE_S, OR1K_INSN_LF_GE_D, OR1K_INSN_LF_GT_S + , OR1K_INSN_LF_GT_D, OR1K_INSN_LF_LT_S, OR1K_INSN_LF_LT_D, OR1K_INSN_LF_LE_S + , OR1K_INSN_LF_LE_D, OR1K_INSN_LF_MADD_S, OR1K_INSN_LF_MADD_D, OR1K_INSN_LF_CUST1_S + , OR1K_INSN_LF_CUST1_D } CGEN_INSN_TYPE; /* Index of `invalid' insn place holder. */ -- cgit v1.1
