2016-03-21arc/opcodes: Use flag operand class to handle multiple flag matchesAndrew Burgess2-25/+31
When parsing the operand instruction flags we don't currently detect the case where multiple flags are provided from the same class set, these will be accepted and the bit values merged together, resulting in the wrong instruction being assembled. For example: adc.n.eq r0,r0,r2 Will assemble without error, yet, upon disassembly, the instruction will actually be: adc.c r0,r0,r2 In a later commit the concept of required flags will be introduced. Required flags are just like normal instruction flags, except that they must be present for the instruction to match. Adding this will allow for simpler instructions in the instruction table, and allow for more sharing of operand extraction and insertion functions. To solve both of the above issues (multiple flags being invalid, and required flags), this commit reworks the flag class mechanism. Currently the flag class is never used. Each instruction can reference multiple flag classes, each flag class has a class type and a set of flags. However, at present, the class type is never used. The current values identify the type of instruction that the flag will be used in, but this is not required information. Instead, this commit discards the old flag classes, and introduces 3 new classes. The first F_CLASS_NONE, is just a NULL marker value, and is only used in the NULL marker flag class. The other two flag classes are F_FLAG_OPTIONAL, and F_FLAG_REQUIRED. The class F_FLAG_OPTIONAL has the property that at most one of the flags in the flag set for that class must be present in the instruction. The "at most" one means that no flags being present is fine. The class F_FLAG_REQUIRED is not currently used, but will be soon. With this class, exactly one of the flags from this class must be present in the instruction. If the flag class contains a single flag, then of course that flag must be present. However, if the flag class contained two or more, then one, and only one of them must be present. gas/ChangeLog: * config/tc-arc.c (find_opcode_match): Move lnflg, and i declarations to start of block.

2016-03-21arc: Add nps400 machine type, and assembler flag.Andrew Burgess2-0/+8
This commit introduces the nps400 machine type as a variant of arc. There's a new flag in the assembler to select this machine type. All other changes are just adding handling of the new machine type into the relevant places. The nps400 is an arc700 variant with some vendor specific instructions added into the instruction set. This commit does not add any of the new instructions, this is just laying the groundwork for future commits. However, in preparation for these new instructions a new opcode define for nps400 has been added to include/opcode/arc.h, this new opcode define is used in the assembler and disassembler along with the existing define for arc700 such that when assembling and disassembling for nps400 the user will have access to all arc700 instructions and all the nps400 vendor extension instructions. bfd/ChangeLog: * archures.c (bfd_mach_arc_nps400): Define. * bfd-in2.h: Regenerate. * cpu-arc.c (arch_info_struct): New entry for nps400, renumber some existing entries to make space. * elf32-arc.c (arc_elf_object_p): Add nps400 case.

2016-03-21arc/gas: default mach is arc700, initialised in md_beginAndrew Burgess2-3/+4
This commit restructures the selection of the default cpu/mach so that the choice is made from md_begin (if the user has not provided a command line choice). This will reduce the amount of change needed in a later patch. At the request of Synopsys, the default architecture changes to ARC700 from this commit, previously the default was a non-existent super-architecture that contained all instructions from all arc variants. There's some clean up associated with removing the default merged architecture, and a small test fix now that the default is ARC700. binutils/ChangeLog: * testsuite/binutils-all/objdump.exp (cpus_expected): Add ARC700 to the architecture list. gas/ChangeLog: * config/tc-arc.c (arc_target): Delay initialisation until arc_select_cpu.

2016-02-02opcodes/cgen: Rework calculation of shift when inserting fieldsAndrew Burgess15-42/+157
The calculation of the shift amount, used to insert fields into the instruction buffer, is not correct when the following conditions are all true: - CGEN_INT_INSN_P is defined, and true. - CGEN_INSN_LSB0_P is true - Total instruction length is greater than the length of a single instruction word (the instruction is made of multiple words) - The word offset is non-zero (the field is outside the first word) When the above conditions are all true, the calculated shift fails to take account of the total instruction length. After this commit the calculation of the shift amount is split into two parts, first we calculate the shift required to get to BIT0 of the word in which the field lives, then we calculate the shift required to place the field within the instruction word. The change in this commit only effects the CGEN_INT_INSN_P defined true case, but changes the code for both CGEN_INSN_LSB0_P true, and false. In the case of CGEN_INSN_LSB0_P being false, the code used to say: shift = total_length - (word_offset + start + length); Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = word_length - start - length; shift = shift_to_word + shift_within_word; From which we can see that in all cases the computed shift value should be unchanged. In the case of CGEN_INSN_LSB0_P being true, the code used to say: shift = (word_offset + start + 1) - length; Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = start + 1 - length; shift = shift_to_word + shift_within_word; In the case where 'total_length == word_length' AND 'word_offset == 0' (which indicates an instruction of a single word), we see that the computed shift value will be unchanged. However, when the total_length and word_length are different, and the word_offset is non-zero then the computed shift value will be different (and correct). opcodes/ChangeLog: * cgen-ibld.in (insert_normal): Rework calculation of shift. * epiphany-ibld.c: Regenerate. * fr30-ibld.c: Regenerate. * frv-ibld.c: Regenerate. * ip2k-ibld.c: Regenerate. * iq2000-ibld.c: Regenerate. * lm32-ibld.c: Regenerate. * m32c-ibld.c: Regenerate. * m32r-ibld.c: Regenerate. * mep-ibld.c: Regenerate. * mt-ibld.c: Regenerate. * or1k-ibld.c: Regenerate. * xc16x-ibld.c: Regenerate. * xstormy16-ibld.c: Regenerate.
