From dc70030aba5a95d6449c57c5a87a83fc902e9a23 Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Thu, 12 Jun 2008 21:44:53 +0000 Subject: [PATCH] * mips.h: Document new field descriptors +Q. (OP_SH_SEQI, OP_MASK_SEQI): New bit mask and shift count for SEQI. opcodes/ * mips-dis.c (print_insn_args): Handle field descriptor +Q. * mips-opc.c (mips_builtin_opcodes): Add Octeon instructions seq, seqi, sne and snei. gas/ * config/tc-mips.c (validate_mips_insn): Handle field descriptor +Q. (mips_ip): Likewise. (macro_build): Likewise. (CPU_HAS_SEQ): New macro. (macro2) : Use it. Emit seq/sne and seqi/snei. gas/testsuite/ * gas/mips/octeon.s, gas/mips/octeon.d: Add tests for seq* and sne*. * gas/mips/octeon-ill.s, gas/mips/octeon-ill.s: Add tests for seqi and snei. --- include/opcode/ChangeLog | 3 +++ include/opcode/mips.h | 5 ++++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/include/opcode/ChangeLog b/include/opcode/ChangeLog index 802ce5a35..32b9728bc 100644 --- a/include/opcode/ChangeLog +++ b/include/opcode/ChangeLog @@ -7,6 +7,9 @@ (OP_SH_CINSPOS, OP_MASK_CINSPOS, OP_SH_CINSLM1, OP_MASK_CINSLM1): New bit masks and shift counts for cins and exts. + * mips.h: Document new field descriptors +Q. + (OP_SH_SEQI, OP_MASK_SEQI): New bit mask and shift count for SEQI. + 2008-04-28 Adam Nemet * mips.h (INSN_MACRO): Move it up to the the pinfo macros. diff --git a/include/opcode/mips.h b/include/opcode/mips.h index 2487f9e64..8d201f62e 100644 --- a/include/opcode/mips.h +++ b/include/opcode/mips.h @@ -222,6 +222,8 @@ Software Foundation, 51 Franklin Street - Fifth Floor, Boston, MA 02110-1301, US #define OP_MASK_CINSPOS 0x1f #define OP_SH_CINSLM1 11 #define OP_MASK_CINSLM1 0x1f +#define OP_SH_SEQI 6 +#define OP_MASK_SEQI 0x3ff /* This structure holds information for a particular instruction. */ @@ -385,6 +387,7 @@ struct mips_opcode "+p" Position field of cins/cins32/exts/exts32.
