From c604a79ad4d47070bbcc0bc082188fb16892ceef Mon Sep 17 00:00:00 2001 From: Jiong Wang Date: Wed, 28 Jun 2017 11:00:55 +0100 Subject: [ARM] Assembler and disassembler support Dot Product Extension This patch add assembler and disassembler support for new Dot Product Extension. The support can be enabled through the new "+dotprod" extension. include/ * opcode/arm.h (FPU_NEON_EXT_DOTPROD): New macro. (FPU_ARCH_DOTPROD_NEON_VFP_ARMV8): New macro. gas/ * config/tc-arm.c (fpu_neon_ext_dotprod): New variable. (neon_scalar_for_mul): Improve comments. (do_neon_dotproduct): New function to encode Dot Product instructions. (do_neon_dotproduct_s): Wrapper function for signed Dot Product instructions. (do_neon_dotproduct_u): Wrapper function for unsigned Dot Product instructions. (insns): New entries for vsdot and vudot. (arm_extensions): New entry for "dotprod". * doc/c-arm.texi: Document new "dotprod" extension. * testsuite/gas/arm/dotprod.s: New test source. * testsuite/gas/arm/dotprod-illegal.s: New test source. * testsuite/gas/arm/dotprod.d: New test. * testsuite/gas/arm/dotprod-thumb2.d: New test. * testsuite/gas/arm/dotprod-illegal.d: New test. * testsuite/gas/arm/dotprod-legacy-arch.d: New test. * testsuite/gas/arm/dotprod-illegal.l: New error file. * testsuite/gas/arm/dotprod-legacy-arch.l: New error file. opcodes/ * arm-dis.c (coprocessor_opcodes): New entries for vsdot and vudot. --- include/opcode/arm.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'include/opcode') diff --git a/include/opcode/arm.h b/include/opcode/arm.h index e2049a0..e11ac7c 100644 --- a/include/opcode/arm.h +++ b/include/opcode/arm.h @@ -93,7 +93,8 @@ #define FPU_CRYPTO_EXT_ARMV8 0x00008000 /* Crypto for ARMv8. */ #define CRC_EXT_ARMV8 0x00004000 /* CRC32 for ARMv8. */ #define FPU_VFP_EXT_ARMV8xD 0x00002000 /* Single-precision FP for ARMv8. */ -#define FPU_NEON_EXT_RDMA 0x00001000 /* v8.1 Adv.SIMD extensions. */ +#define FPU_NEON_EXT_RDMA 0x00001000 /* v8.1 Adv.SIMD extensions. */ +#define FPU_NEON_EXT_DOTPROD 0x00000800 /* Dot Product extension. */ /* Architectures are the sum of the base and extensions.
