2020-06-09x86-64: adjust far indirect branch handlingJan Beulich8-1/+160
An unwanted side effect of 5990e377e5a3 ("x86-64: Intel64 adjustments for insns dealing with far pointers") was that with -mintel64 LCALL and LJMP would now default to 64-bit operand size. Since 64-bit far branches aren't portable, the default operand size should still be 32-bit. However, since the 64-bit variant is permitted, an ambiguous operand warning should be issued. As to the actual code change, please note that the conditional surrounding the switch() that gets adjusted covers several cases which are of no interest to or benign in 64-bit mode, hence the new conditional added can be quite a bit less involved.
2020-06-09x86: don't ignore mandatory pseudo prefixesJan Beulich6-26/+89
{vex}, {vex3}, and {evex} are mandatory prefixes, and hence should not be randomly ignored. Fix this for insns without operands as well as for insns referencing the high 16 [XYZ]MM registers. To achieve the former, re-purpose VEX_check_operands(), renaming it to VEX_check_encoding() and moving its only operand check to check_VecOperands(). This involves fixing a testcase relying on {vex2} to get ignored.
2020-06-09PowerPC64: Downgrade ifunc with textrel error to a warningAlan Modra2-12/+13
For ppc64 I set flags when recording the dynamic relocation rather than when allocating space. That allows you to distinguish three cases: 1) The dynamic ifunc relocation is in an executable and will always be to an ifunc resolver in the executable. 2) The dynamic ifunc relocation is in a shared library which provides an ifunc resolver, but that may be overridden at runtime to use a resolver in another binary. 3) The dynamic ifunc relocation is not to a locally defined ifunc resolver. Case (3) won't cause a segfault trying to run resolver code that is non-exec on older glibc. I made case (1) an error for ppc64, but since newer glibc ld.so does allow running ifunc resolvers when segments are writable I suppose I should downgrade that to a warning like case (2). * elf64-ppc.c (struct ppc_link_hash_table): Delete maybe_local_ifunc_resolver field. (build_global_entry_stubs_and_plt): Set local_ifunc_resolver in cases where maybe_local_ifunc_resolver was set. (ppc64_elf_relocate_section): Likewise.

2020-06-08gdb: add field::type / field::set_typeSimon Marchi16-71/+90
Add the `type` and `set_type` methods on `struct field`, in order to remoremove the `FIELD_TYPE` macro. In this patch, the `FIELD_TYPE` macro is changed to use `field::type`, so all the call sites that are useused to set the field's type are changed to use `field::set_type`. The next patch will remove `FIELD_TYPE` completely. Note that because of the name clash between the existing field named `type` and the new method, I renamed the field `m_type`. It is not private per-se, because we can't make `struct field` a non-POD yet, but it should be considered private anyway (not accessed outside `struct field`). gdb/ChangeLog: * gdbtypes.h (struct field) <type, set_type>: New methods. Rename `type` field to... <m_type>: ... this. Change references throughout to use type or set_type methods. (FIELD_TYPE): Use field::type.

2020-06-08x86: also handle %k<N> and %bnd<N> in debugging helpersJan Beulich2-1/+7
Adjustment of this function was missed when support for the respective registers was added.
2020-06-08x86: simplify check_byte_reg()Jan Beulich2-15/+9
With the introduction of what right now is the very first conditional in the function's loop (commit dc821c5f9ae5 ["x86: replace Reg8, Reg16, Reg32, and Reg64"]), the last if() in the same loop has become pointless - retain just its body.
2020-06-08x86: restrict %tr<N> visibilityJan Beulich5-2/+24
First of all, these registers have never been available on any 64-bit CPU, and hence should not be recognized in 64-bit mode. But even before that they had already disappeared - also don't recognize them when 586 or 686 architectures were explicitly set.
2020-06-08ix86: enable 2nd CFI testJan Beulich3-7/+13

2020-06-08x86: also allow %st(N) in CFI directivesJan Beulich3-1/+9
In 0e0eea782025 ("x86: x87-related adjustments") I screwed up CFI directives with FPU support disabled, by moving the conditional there across a check of "allow_pseudo_reg". Add the missing check.
2020-06-08x86: restrict use of register aliasesJan Beulich9-66/+154
Register aliases (created e.g. via .set) check their target register at the time of creation of the alias. While this makes sense, it's not enough: The underlying register must also be "visible" at the time of use. Wrong use of such aliases would lead to internal errors in e.g. add_prefix() or build_modrm_byte(). Split the checking part of parse_real_register() into a new helper function and use it also from the latter part of parse_register() (at the same time replacing a minor open coded part of it). Since parse_register() returning NULL already has a meaning, a fake new "bad register" indicator gets added, which all callers need to check for.

2020-06-06ld -plugin options when plugins are disabledAlan Modra3-1/+13
This patch makes ld accept and ignore -plugin options when configured with --disable-plugins. The idea is to allow using a linker built without plugin support with a gcc built with plugin support. Quite obviously such a combination won't work if using LTO, but gcc has a habit of passing a bunch of -plugin and -plugin-opt arguments to ld even when not generating or linking LTO objects. Why do I want to do this? Well, it lets me and other binutils developers answer the question as to whether plugin support breaks binutils in some areas. Which it does for some targets. * lexsup.c (ld_options): Accept -plugin and -plugin-opt when !ENABLE_PLUGINS. * testsuite/lib/ld-lib.exp (check_plugin_api_available): Adjust.

When setting the window title of a tui frame we do this: gdb::unique_xmalloc_ptr<char> value = python_string_to_host_string (<python-object>); ... win->window->title = value.get (); The problem here is that 'get ()' only borrows the pointer from value, when value goes out of scope the pointer will be freed. As a result, the tui frame will be left with a pointer to undefined memory contents. Instead we should be using 'value.release ()' to take ownership of the pointer from value. gdb/ChangeLog: * python/py-tui.c (gdbpy_tui_set_title): Use release, not get, to avoid use after free.

2020-06-05RISC-V: The object without priv spec attributes can be linked with any object.Nelson Chu15-3/+133
bfd/ * elfnn-riscv.c (riscv_merge_attributes): Add new boolean priv_may_conflict, in_priv_zero and out_priv_zero to decide whether the object can be linked according to it's priv attributes. The object without any priv spec attributes can be linked with others. If the first input object doesn't contain any priv attributes, then we need to copy the setting from the next input one. Also report more detailed error messages to user. ld/ * testsuite/ld-riscv-elf/attr-merge-priv-spec.d: Rename to attr-merge-priv-spec-01.d. * testsuite/ld-riscv-elf/attr-merge-priv-spec-c.s: Set priv spec to 1.11. * testsuite/ld-riscv-elf/attr-merge-priv-spec-d.s: Empty priv spec setting. * testsuite/ld-riscv-elf/attr-merge-priv-spec-02.d: New testcase. * testsuite/ld-riscv-elf/attr-merge-priv-spec-03.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-01.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-02.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-03.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-04.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-05.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-failed-06.d: Likewise. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated.
2020-06-05RISC-V: Don't generate the ELF privilege attributes when no CSR are used.Nelson Chu27-57/+75
gas/ * config/tc-riscv.c (explicit_csr): New static boolean. Used to indicate CSR are explictly used. (riscv_ip): Set explicit_csr to TRUE if any CSR is used.

Otherwise, don't generate them when no CSR are used. * testsuite/gas/riscv/attribute-01.d: Remove the priv attributes. * testsuite/gas/riscv/attribute-02.d: Likewise. * testsuite/gas/riscv/attribute-03.d: Likewise. * testsuite/gas/riscv/attribute-04.d: Likewise. * testsuite/gas/riscv/attribute-05.d: Likewise. * testsuite/gas/riscv/attribute-06.d: Likewise. * testsuite/gas/riscv/attribute-07.d: Likewise. * testsuite/gas/riscv/attribute-08.d: Likewise. * testsuite/gas/riscv/attribute-09.d: Likewise. * testsuite/gas/riscv/attribute-10.d: Likewise. * testsuite/gas/riscv/attribute-unknown.d: Likewise. * testsuite/gas/riscv/attribute-11.s: New testcase. * testsuite/gas/riscv/attribute-11.d: New testcase.
