From 1e2e8c529c1cf4fcc8cbae382aa0a653d0b65da6 Mon Sep 17 00:00:00 2001 From: Andreas Krebbel Date: Fri, 16 Jan 2015 12:19:21 +0100 Subject: S/390: Add support for IBM z13. - 32 128 bit vector registers (overlapping with the existing 16 64 bit floating point registers) - vector double instructions - vector integer instructions - scalar vector instructions (allowing to have more floating point registers for scalar operations) - vector string instructions gas/ChangeLog: * config/tc-s390.c (struct pd_reg): Remove. (pre_defined_registers): Remove. (REG_NAME_CNT): Remove. (reg_name_search): Calculate the register number instead of doing a lookup. (register_name, tc_s390_regname_to_dw2regnum): Adopt to the new reg_name_search signature. (s390_parse_cpu): Support the new arch string z13. (s390_insert_operand): Support for vector registers with the extra field for the fifth bit of each vector register operand. (md_gather_operand): Adjust to the new handling of optional parameters. * doc/as.texinfo: Document the z13 cpu string. gas/testsuite/ChangeLog: * gas/s390/esa-g5.d: Add a variant without the optional operand. * gas/s390/esa-g5.s: Likewise. * gas/s390/esa-z9-109.d: Likewise. * gas/s390/esa-z9-109.s: Likewise. * gas/s390/zarch-z9-109.d: Likewise. * gas/s390/zarch-z9-109.s: Likewise. * gas/s390/zarch-z10.d: For variants with a zero optional argument it is not dumped by objdump anymore. * gas/s390/zarch-zEC12.d: Likewise. * gas/s390/zarch-z13.d: New file. * gas/s390/zarch-z13.s: New file. * gas/s390/s390.exp: Run the test for the z13 files. include/opcode/ChangeLog: * s390.h (s390_opcode_cpu_val): Add S390_OPCODE_Z13. ld/testsuite/ChangeLog: * ld-s390/tlsbin.dd: The nopr register operand is optional and not printed if 0 anymore. opcodes/ChangeLog: * s390-dis.c (s390_extract_operand): Support vector register operands. (s390_print_insn_with_opcode): Support new operands types and add new handling of optional operands. * s390-mkopc.c (s390_opcode_mode_val, s390_opcode_cpu_val): Remove and include opcode/s390.h instead. (struct op_struct): New field `flags'. (insertOpcode, insertExpandedMnemonic): New parameter `flags'. (dumpTable): Dump flags. (main): Parse flags from the s390-opc.txt file. Add z13 as cpu string. * s390-opc.c: Add new operands types, instruction formats, and instruction masks. (s390_opformats): Add new formats for .insn. * s390-opc.txt: Add new instructions. --- include/opcode/ChangeLog | 4 ++++ include/opcode/s390.h | 23 ++++++++++++++++++++--- 2 files changed, 24 insertions(+), 3 deletions(-) (limited to 'include/opcode') diff --git a/include/opcode/ChangeLog b/include/opcode/ChangeLog index a5e79f4..f97e56f 100644 --- a/include/opcode/ChangeLog +++ b/include/opcode/ChangeLog @@ -1,3 +1,7 @@ +2015-01-16 Andreas Krebbel + + * s390.h (s390_opcode_cpu_val): Add S390_OPCODE_Z13. + 2015-01-01 Alan Modra Update year range in copyright notice of all files. diff --git a/include/opcode/s390.h b/include/opcode/s390.h index 79e9a60..b47709c 100644 --- a/include/opcode/s390.h +++ b/include/opcode/s390.h @@ -41,9 +41,13 @@ enum s390_opcode_cpu_val S390_OPCODE_Z10, S390_OPCODE_Z196, S390_OPCODE_ZEC12, + S390_OPCODE_Z13, S390_OPCODE_MAXCPU }; +/* Instruction specific flags. */ +#define S390_INSTR_FLAG_OPTPARM 0x1 + /* The opcode table is an array of struct s390_opcode. */ struct s390_opcode @@ -74,6 +78,9 @@ struct s390_opcode /* First cpu this opcode is available for. */ enum s390_opcode_cpu_val min_cpu; + + /* Instruction specific flags. */ + unsigned int flags; }; /* The table itself is sorted by major opcode number, and is otherwise @@ -86,7 +93,7 @@ extern const int s390_num_opcodes; extern const struct s390_opcode s390_opformats[]; extern const int s390_num_opformats; -/* Values defined for the flags field of a struct powerpc_opcode. */ +/* Values defined for the flags field of a struct s390_opcode. */ /* The operands table is an array of struct s390_operand. */ @@ -103,7 +110,7 @@ struct s390_operand }; /* Elements in the table are retrieved by indexing with values from - the operands field of the powerpc_opcodes table. */ + the operands field of the s390_opcodes table. */ extern const struct s390_operand s390_operands[]; @@ -151,4 +158,14 @@ extern const struct s390_operand s390_operands[]; /* The operand needs to be a valid GP or FP register pair. */ #define S390_OPERAND_REG_PAIR 0x800 - #endif /* S390_H */ +/* This operand names a vector register.
