2018-07-12Add remainder of Em16 restrictions for AArch64 gas.Tamar Christina
This adds the missing Em16 constraints the rest of the instructions requiring them and also adds a testcase to test all the instructions so these are checked from now on. The Em16 operand constrains the valid registers to the lower 16 registers when used with a half precision qualifier.

2018-06-29[Patch AArch64] Warn on unpredictable stlxrb , stlxrh and stlxr cases.Ramana Radhakrishnan
A recent case in golang highlighted that gas wasn't warning on these unpredictable cases in the architecture. Fixed thusly. I need to audit gcc to make sure we have early clobbers on the patterns but that's a separate patch. Tested aarch64-none-elf and gas Ok ?

2018-06-29Fix AArch64 encodings for by element instructions.Tamar Christina
Some instructions in Armv8-a place a limitation on FP16 registers that can be used as the register from which to select an element from. e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction does not apply for all instructions, e.g. fcmla does not have this restriction as it gets an extra bit from the M field. Unfortunately, this restriction to S_H was added for all _Em operands before, meaning for a large number of instructions you couldn't use the full register file. This fixes the issue by introducing a new operand _Em16 which applies this restriction only when paired with S_H and leaves the _Em and the other qualifiers for _Em16 unbounded (i.e. using the full 5 bit range). Also the patch updates all instructions that should be affected by this. opcodes/ PR binutils/23192 * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise. * aarch64-dis.c (aarch64_ext_reglane): Add AARCH64_OPND_Em16 constraint. * aarch64-opc.c (operand_general_constraint_met_p, aarch64_print_operand): Likewise. * aarch64-tbl.h (aarch64_opcode_table): Change Em to Em16 for smlal, smlal2, fmla, fmls, fmul, fmulx, sqrdmlah, sqrdlsh, fmlal, fmlsl, fmlal2, fmlsl2.

2018-06-22Correct negs aliasing on AArch64.Tamar Christina
This patch fixes a disassembly issue with the aliases to subs with a shifted register. The subs instruction with the zero register as destination is supposed to alias to cmp and when the first input register is the zero register the subs is supposed to be aliased to negs. This means that a subs with destination and first input registers the zero register is supposed to be a cmp. This is done by raising the priority of the cmp alias. opcodes/ * aarch64-tbl.h (aarch64_opcode_table): Fix alias flag for negs * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. gas/ * testsuite/gas/aarch64/addsub.s: Add negs to zero reg test. * testsuite/gas/aarch64/addsub.d: Likewise.

2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL. Problem 2 (in zlib/): Makefile.am: error: required file './INSTALL' not found Makefile.am: 'automake --add-missing' can install 'INSTALL' Makefile.am: error: required file './NEWS' not found Makefile.am: error: required file './AUTHORS' not found Makefile.am: error: required file './COPYING' not found Makefile.am: 'automake --add-missing' can install 'COPYING' Solution 2: Add the foreign option to AUTOMAKE_OPTIONS. Problem 3: doc/Makefile.am:20: error: support for Cygnus-style trees has been removed Solution 3: Remove the cygnus options. Problem 4: Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Solution 4: Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is already defined earlier). Problem 5: doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 5: Rename .texinfo files to .texi. Problem 6: doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 6: Remove the hack at the bottom of doc/Makefile.am and use the info-in-builddir automake option. Problem 7: doc/Makefile.am:35: error: required file '../texinfo.tex' not found doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex' Solution 7: Use the no-texinfo.tex automake option. We also have one in texinfo/texinfo.tex, not sure if we should point to that, or move it (or a newer version of it added with automake --add-missing) to top-level. Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. Solution 8: Use subdir-objects, that means adjusting references to some .o that will now be in config/.

2018-06-01x86: don't emit REX.W for SLDT and STRJan Beulich
Just like for other selector register reads, they're unnecessary and should hence be avoided.
2018-06-01x86: relax redundant REX prefix checkJan Beulich
All REX bits can be specified via individual prefixes. Redundancy should only be reported on a per-bit basis. Note that I originally had further checks added to the test case, checking the effect also on PDEP. I had to strip those, because my patch to correctly handle those (https://sourceware.org/ml/binutils/2017-02/msg00280.html) was rejected. I continue to think that there should not be any new prefix introduced to handle the VEX case - whether the encoding of an insn requires VEX et al should not be of immediate interest to the programmer.
2018-06-01x86: simplify control register checkJan Beulich
... as is already done elsewhere: There's no need for the use of operand_type_equal() here - the bit identifying control registers isn't used for any other purposes.
2018-06-01x86: tighten condition for emitting LOCK on control register accessesJan Beulich
The control register is never expressed by REX.B; this bit only affects the involved GPR. Also only one of the operands can have its "control" flag set, so only check the correct operand.

2018-05-15Implement Read/Write constraints on system registers on AArch64Tamar Christina
This patch adds constraints for read and write only system registers with the msr and mrs instructions. The code will treat having both flags set and none set as the same. These flags add constraints that must be matched up. e.g. a system register with a READ only flag set, can only be used with mrs. If The constraint fails a warning is emitted. Examples of the warnings generated: test.s: Assembler messages: test.s:5: Warning: specified register cannot be written to at operand 1 -- `msr dbgdtrrx_el0,x3' test.s:7: Warning: specified register cannot be read from at operand 2 -- `mrs x3,dbgdtrtx_el0' test.s:8: Warning: specified register cannot be written to at operand 1 -- `msr midr_el1,x3' and disassembly notes: 0000000000000000 <main>: 0: d5130503 msr dbgdtrtx_el0, x3 4: d5130503 msr dbgdtrtx_el0, x3 8: d5330503 mrs x3, dbgdtrrx_el0 c: d5330503 mrs x3, dbgdtrrx_el0 10: d5180003 msr midr_el1, x3 ; note: writing to a read-only register. Note that because dbgdtrrx_el0 and dbgdtrtx_el0 have the same encoding, during disassembly the constraints are use to disambiguate between the two. An exact constraint match is always prefered over partial ones if available. As always the warnings can be suppressed with -w and also be made errors using warnings as errors. binutils/ PR binutils/21446 * doc/binutils.texi (-M): Document AArch64 options. gas/ PR binutils/21446 * testsuite/gas/aarch64/illegal-sysreg-2.s: Fix pmbidr_el1 test. * testsuite/gas/aarch64/illegal-sysreg-2.l: Likewise. * testsuite/gas/aarch64/illegal-sysreg-2.d: Likewise. * testsuite/gas/aarch64/sysreg-diagnostic.s: New. * testsuite/gas/aarch64/sysreg-diagnostic.l: New. * testsuite/gas/aarch64/sysreg-diagnostic.d: New. include/ PR binutils/21446 * opcode/aarch64.h (F_SYS_READ, F_SYS_WRITE): New. opcodes/ PR binutils/21446 * aarch64-asm.c (opintl.h): Include.

2018-05-15Allow non-fatal errors to be emitted and for disassembly notes be placed on ↵Tamar Christina
AArch64 This patch adds a new platform option "notes" that can be used to indicate if disassembly notes should be placed in the disassembly as comments. These notes can contain information about a failing constraint such as reading from a write-only register. The disassembly will not be blocked because of this but -M notes will emit a comment saying that the operation is not allowed. For assembly this patch adds a new non-fatal status for errors. This is essentially a warning. The reason for not creating an actual warning type is that this causes the interaction between the ordering of warnings and errors to be problematic. Currently the error buffer is almost always filled because of the way operands are matched during assembly. An earlier template may have put an error there that would only be displayed if no other template matches or generates a higher priority error. But by definition a warning is lower priority than a warning, so the error (which is incorrect if another template matched) will supersede the warning. By treating warnings as errors and only later relaxing the severity this relationship keeps working and the existing reporting infrastructure can be re-used. binutils/ PR binutils/21446 * doc/binutils.texi (-M): Document AArch64 options. * NEWS: Document notes and warnings. gas/ PR binutils/21446 * config/tc-aarch64.c (print_operands): Indicate no notes.

2018-05-15Modify AArch64 Assembly and disassembly functions to be able to fail and ↵Tamar Christina
report why. This patch if the first patch in a series to add the ability to add constraints to system registers that an instruction must adhere to in order for the register to be usable with that instruction. These constraints can also be used to disambiguate between registers with the same encoding during disassembly. This patch adds a new flags entry in the sysreg structures and ensures it is filled in and read out during assembly/disassembly. It also adds the ability for the assemble and disassemble functions to be able to gracefully fail and re-use the existing error reporting infrastructure. The return type of these functions are changed to a boolean to denote success or failure and the error structure is passed around to them. This requires aarch64-gen changes so a lot of the changes here are just mechanical. gas/ PR binutils/21446 * config/tc-aarch64.c (parse_sys_reg): Return register flags.
