2016-09-21[AArch64][SVE 28/32] Add SVE FP immediate operandsRichard Sandiford1-25/+32
This patch adds support for the new SVE floating-point immediate operands. One operand uses the same 8-bit encoding as base AArch64, but in a different position. The others use a single bit to select between two values. One of the single-bit operands is a choice between 0 and 1, where 0 is not a valid 8-bit encoding. I think the cleanest way of handling these single-bit immediates is therefore to use the IEEE float encoding itself as the immediate value and select between the two possible values when encoding and decoding. As described in the covering note for the patch that added F_STRICT, we get better error messages by accepting unsuffixed vector registers and leaving the qualifier matching code to report an error. This means that we carry on parsing the other operands, and so can try to parse FP immediates for invalid instructions like: fcpy z0, #2.5 In this case there is no suffix to tell us whether the immediate should be treated as single or double precision. Again, we get better error messages by picking one (arbitrary) immediate size and reporting an error for the missing suffix later. include/ * opcode/aarch64.h (AARCH64_OPND_SVE_FPIMM8): New aarch64_opnd.

2016-09-21[AArch64][SVE 27/32] Add SVE integer immediate operandsRichard Sandiford1-38/+62
This patch adds the new SVE integer immediate operands. There are three kinds: - simple signed and unsigned ranges, but with new widths and positions. - 13-bit logical immediates. These have the same form as in base AArch64, but at a different bit position. In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical immediate <limm> is not allowed to be a valid DUP immediate, since DUP is preferred over DUPM for constants that both instructions can handle. - a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}". In some contexts the operand is signed and in others it's unsigned. As an extension, we allow shifted immediates to be written as a single integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the shiftless form as the preferred disassembly, except for the special case of "#0, LSL #8" (a redundant encoding of 0). include/ * opcode/aarch64.h (AARCH64_OPND_SIMM5): New aarch64_opnd.

2016-09-21[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALEDRichard Sandiford1-6/+8
Some SVE instructions count the number of elements in a given vector pattern and allow a scale factor of [1, 16] to be applied to the result. This scale factor is written ", MUL #n", where "MUL" is a new operator. E.g.: UQINCD X0, POW2, MUL #2 This patch adds support for this kind of operand. All existing operators were shifts of some kind, so there was a natural range of [0, 63] regardless of context. This was then narrowered further by later checks (e.g. to [0, 31] when used for 32-bit values). In contrast, MUL doesn't really have a natural context-independent range. Rather than pick one arbitrarily, it seemed better to make the "shift" amount a full 64-bit value and leave the range test to the usual operand-checking code. I've rearranged the fields of aarch64_opnd_info so that this doesn't increase the size of the structure (although I don't think its size is critical anyway). include/ * opcode/aarch64.h (AARCH64_OPND_SVE_PATTERN_SCALED): New aarch64_opnd.

2016-09-21[AArch64][SVE 23/32] Add SVE pattern and prfop operandsRichard Sandiford1-5/+7
The SVE instructions have two enumerated operands: one to select a vector pattern and another to select a prefetch operation. The latter is a cut-down version of the base AArch64 prefetch operation. Both types of operand can also be specified as raw enum values such as #31. Reserved values can only be specified this way. If it hadn't been for the pattern operand, I would have been tempted to use the existing parsing for prefetch operations and add extra checks for SVE. However, since the patterns needed new enum parsing code anyway, it seeemed cleaner to reuse it for the prefetches too. Because of the small number of enum values, I don't think we'd gain anything by using hash tables. include/ * opcode/aarch64.h (AARCH64_OPND_SVE_PATTERN): New aarch64_opnd.
