2016-04-22MIPS/GAS: Fix an ISA override not lifting ABI restrictionsMaciej W. Rozycki46-8/+775
Correct a regression introduced with commit 919731affbef ("Add MIPS .module directive") causing code like: .set mips3 dli $2, 0x9000000080000000 to fail assembly with the following error message produced: Error: number (0x9000000080000000) larger than 32 bits if built with `mips3' selected as the global ISA (e.g. `-march=mips3'). This is because a `.set' directive doing an ISA override does not lift the ABI restriction on register sizes if the ISA remains unchanged. Previously the directive always set register sizes from the ISA chosen, which is what some code expects. Restore the old semantics then. gas/ * config/tc-mips.c (code_option_type): New enum.

2016-04-20[AArch64] Support RAS extension for ARMv8 onwards.Matthew Wahab8-0/+249
The RAS extension was introduced as part of the ARMv8.2 architecture where it is a required feature. It is also available as an optional feature for ARMv8 and ARMv8.1. In binutils, the RAS extension is currently enabled by default for -march=armv8.2-a but is not available for -march=armv8 or -march=armv8.1-a. This patch adds the feature extension '+ras' to enable the RAS extension for ARMv8 and ARMv8.1, it is disabled by default. gas/ 2016-04-20 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_features): Add "ras". * doc/c-aarch64.texi (AArch64 Extensions): Add "ras". * testsuite/gas/aarch64/armv8-ras-1.d: New. * testsuite/gas/aarch64/armv8-ras-1.s: New. * testsuite/gas/aarch64/illegal-ras-1.d: New. * testsuite/gas/aarch64/illegal-ras-1.s: New.

2016-04-15remove pointless assignmentTrevor Saunders2-5/+8
Presumably this was supposed to be regname[sizeof (regname) - 1] but was typoed to regname[sizeof (rename) - 1]. However that should be unnecessary because sprintf should null terminate. As is this assignment is invalid ISO C because rename refers to the function rename (), and sizeof on functions is undefined. In GNU C C the size of functions is 1 so the expression is the same as regname[0]. The following call to sprintf () clearly will over right that, so the statement either has no effect or is invalid. Given that it seems safe to just remove it. While we are there correct the size of regname, and switch from snprintf to sprintf since we know the exact length of the result. gas/ChangeLog: 2016-04-15 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-mips.c (md_begin): Remove useless assignment.

2016-04-13MIPS/GAS: Relax branches to symbols resolved at link timeMaciej W. Rozycki15-10/+193
Where branch relaxation is enabled emit the long sequence for branches whose distance cannot be determined, i.e. to symbols that are undefined or in a different segment. These symbols are only resolved at link time and therefore the longer sequence ensures the branch target is in range, which cannot be guaranteed with a direct branch. This is the opposite to the current implementation, originally proposed here: <https://sourceware.org/ml/binutils/2002-09/msg00218.html>. The proposal was then extensively discussed before the final version was posted here: <https://sourceware.org/ml/binutils/2002-10/msg00191.html> and eventually committed: commit 4a6a3df43dbb37853a7b88b10ae97d9ec5daf987 Author: Alexandre Oliva <aoliva@redhat.com> Date: Sat Oct 12 05:23:33 2002 +0000 The case considered here was not commented in the review however and the original version remains. With branch relaxation enabled it makes more sense to do it consistently, so that all code impure with respect to branch distances can be linked. Direct branches are still produced for the cases concerned where branch relaxation is disabled, which is the default. gas/ * config/tc-mips.c (relaxed_branch_length): Use the long sequence where the distance cannot be determined.

2016-04-07gas/arc: Handle multiple arc_opcode chains for same mnemonicAndrew Burgess2-12/+69
This commit completes support for having multiple instructions with the same mnemonic in non-contiguous blocks within the arc_opcodes table. The commit adds an iterator mechanism for the arc_opcode_hash_entry structure, which is then used in find_opcode_match to consider all arc_opcode entries with the same mnemonic, even when these instructions are stored in non-contiguous blocks. I extend the comment on the arc_opcodes table to discuss how entries within the table are organised, and to mention how instructions can be split into multiple groups if needed, but that the table is still searched in table order. There should be no user visible changes after this commit. gas/ChangeLog: * config/tc-arc.c (struct arc_opcode_hash_entry_iterator): New structure. (arc_opcode_hash_entry_iterator_init): New function. (arc_opcode_hash_entry_iterator_next): New function. (find_opcode_match): Iterate over all arc_opcode entries referenced by the arc_opcode_hash_entry passed in as a parameter. opcodes/ChangeLog: * arc-opc.c (arc_opcodes): Extend comment to discus table layout.
2016-04-07gas/arc: Additional work to support multiple arc_opcode chainsAndrew Burgess2-35/+46
Building on earlier commits, this commit moves along support for having multiple arc_opcode entries in the arc_opcodes table that have the same mnemonic (name) field, but are not stored in a contiguous block in the table. In this commit we support looking up the arc_opcode_hash_entry from the hash table, and passing this along to the find_opcode_match function, which then finds the specific arc_opcode that we're assembling. We still don't actually support the multiple chains of arc_opcode entries in this commit, but the limitation is now isolated to the find_opcode_match function. There is no user visible change after this commit. gas/ChangeLog: * config/tc-arc.c (arc_find_opcode): Now returns arc_opcode_hash_entry pointer. (find_opcode_match): Update argument type, extract arc_opcode from incoming arc_opcode_hash_entry. (find_special_case_pseudo): Update return type. (find_special_case_flag): Update return type. (find_special_case): Update return type. (assemble_tokens): Lookup arc_opcode_hash_entry based on instruction mnemonic, then use find_opcode_match to identify specific arc_opcode.
2016-04-07gas/arc: Modify structure used to hold opcodesAndrew Burgess2-10/+65
The arc assembler builds a hash table to hold references to arc_opcode entries in the arc_opcodes table. This hash assumes that each mnemonic will always appear in a contiguous blocks within the arc_opcodes table; all ADD instruction will be together, all AND instructions will likewise be together and so on. The problem with this is that as different variations of arc are added, then it is often more convenient to split instructions apart, so all the base ADD instructions are together, but, variants of ADD specific to one variation of arc are grouped with other instructions specific to that arc variant. The current data structures don't support splitting the instructions in this way. This commit is a first step towards addressing this limitation. In this commit the hash table that currently holds arc_opcode pointers directly, instead holds a pointer to a new, intermediate, data structure. This new data structure holds the pointer to the arc_opcode. In this way, we can, in the future support having the intermediate structure hold multiple pointers to different arc_opcode groups. There should be no visible functional change after this commit. gas/ChangeLog: * config/tc-arc.c (struct arc_opcode_hash_entry): New structure. (arc_find_opcode): New function. (find_special_case_pseudo): Use arc_find_opcode. (find_special_case_flag): Likewise. (assemble_tokens): Likewise. (md_begin): Build hash using struct arc_opcode_hash_entry.

2016-04-07gas/arc: Allow greater range of characters into flag namesAndrew Burgess2-1/+7
An upcoming commit will add a new arc instruction flag that uses characters that have never appeared in an arc instruction flag before. Currently the assembler is very conservative about which characters can or cannot appear in an instruction flag. This commit relaxes these constraints a little. After this commit all alpha-numeric characters are now allowed into instruction flags. This complete set is not required for the upcoming change, however, having this slightly larger set does not impact the assemblers ability to correctly parse input, but does make it easier to add new flag to the instruction table. gas/ChangeLog: * config/tc-arc.c (tokenize_flags): Allow greater range of characters into flag names.
2016-04-07gas/arc: Remove preprocess_operands functionAndrew Burgess2-46/+40
The preprocess_operands function changes the incoming list of assembler tokens based on the assumption that the first arc_operand found will be the same instruction class as all of the arc_operands for the same mnemonic. Though this assumption is probably fine, removing this assumption, and pushing the token change down into assemble_tokens makes the code no more complex, and might even be easier to follow. There should be no user visible changes after this commit. gas/ChangeLog: * config/tc-arc.c (find_opcode_match): Handle O_symbol case, add new de_fault label. (preprocess_operands): Delete. (assemble_tokens): Remove call to preprocess_operands.
