x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA levels: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250 Update GNU_PROPERTY_X86_ISA_1_XXX macros: https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13 in x86 ELF binaries to indicate that micro-architecture ISA levels required to execute the binary: #define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2) #define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2) #define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0) #define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1) #define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2) The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX. In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2 directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4 instructions. Add -z x86-64-v[234] linker command line option to mark x86-64-v[234] ISA level as needed. Also add #define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11) for mask registers. bfd/ PR gas/26703 * elf-linker-x86.h (elf_linker_x86_params): Add isa_level. * elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Merge GNU_PROPERTY_X86_ISA_1_V[234].

MSP430: Support relocations for subtract expressions in .uleb128 directives
Link-time relaxations of branches are common for MSP430, given that GCC
can generate pessimal branch instructions, and the
-mcode-region=either/-mdata-region=either options to shuffle sections
can further change the type of branch instruction required.
These relaxations can result in invalid code when .uleb128
directives, used in the .gcc_except_table section, are used to calculate
the distance between two labels. A value for the .uleb128 directive is
calculated at assembly-time, and can't be updated at link-time, even if
relaxation causes the distance between the labels to change.
This patch adds relocations for subtract expressions in .uleb128
directives, to allow the linker to re-calculate the value of these
expressions after relaxation has been performed.

libctf, binutils, include, ld: gettextize and improve error handling
This commit follows on from the earlier commit "libctf, ld, binutils: add textual error/warning reporting for libctf" and converts every error in libctf that was reported using ctf_dprintf to use ctf_err_warn instead, gettextizing them in the process, using N_() where necessary to avoid doing gettext calls unless an error message is actually generated, and rephrasing some error messages for ease of translation. This requires a slight change in the ctf_errwarning_next API: this API is public but has not been in a release yet, so can still change freely. The problem is that many errors are emitted at open time (whether opening of a CTF dict, or opening of a CTF archive): the former of these throws away its incompletely-initialized ctf_file_t rather than return it, and the latter has no ctf_file_t at all. So errors and warnings emitted at open time cannot be stored in the ctf_file_t, and have to go elsewhere. We put them in a static local in ctf-subr.c (which is not very thread-safe: a later commit will improve things here): ctf_err_warn with a NULL fp adds to this list, and the public interface ctf_errwarning_next with a NULL fp retrieves from it. We need a slight exception from the usual iterator rules in this case: with a NULL fp, there is nowhere to store the ECTF_NEXT_END "error" which signifies the end of iteration, so we add a new err parameter to ctf_errwarning_next which is used to report such iteration-related errors. (If an fp is provided -- i.e., if not reporting open errors -- this is optional, but even if it's optional it's still an API change. This is actually useful from a usability POV as well, since ctf_errwarning_next is usually called when there's been an error, so overwriting the error code with ECTF_NEXT_END is not very helpful! So, unusually, ctf_errwarning_next now uses the passed fp for its error code *only* if no errp pointer is passed in, and leaves it untouched otherwise.) ld, objdump and readelf are adapted to call ctf_errwarning_next with a NULL fp to report open errors where appropriate. The ctf_err_warn API also has to change, gaining a new error-number parameter which is used to add the error message corresponding to that error number into the debug stream when LIBCTF_DEBUG is enabled: changing this API is easy at this point since we are already touching all existing calls to gettextize them. We need this because the debug stream should contain the errno's message, but the error reported in the error/warning stream should *not*, because the caller will probably report it themselves at failure time regardless, and reporting it in every error message that leads up to it leads to a ridiculous chattering on failure, which is likely to end up as ridiculous chattering on stderr (trimmed a bit): CTF error: `ld/testsuite/ld-ctf/A.c (0): lookup failure for type 3: flags 1: The parent CTF dictionary is unavailable' CTF error: `ld/testsuite/ld-ctf/A.c (0): struct/union member type hashing error during type hashing for type 80000001, kind 6: The parent CTF dictionary is unavailable' CTF error: `deduplicating link variable emission failed for ld/testsuite/ld-ctf/A.c: The parent CTF dictionary is unavailable' ld/.libs/lt-ld-new: warning: CTF linking failed; output will have no CTF section: `The parent CTF dictionary is unavailable' We only need to be told that the parent CTF dictionary is unavailable *once*, not over and over again! errmsgs are still emitted on warning generation, because warnings do not usually lead to a failure propagated up to the caller and reported there. Debug-stream messages are not translated.

Two fixes in dwarf-mode.el
This fixes a couple of small problems in dwarf-mode.el.
First, I noticed that for an attribute like:
<2><136c>: Abbrev Number: 11 (DW_TAG_member)
<136d> DW_AT_name : t
... the "t" would not be font-locked using the function name face.
The problem here is that the regexp assumed the indirect string
format, like:
<12ac> DW_AT_name : (indirect string, offset: 0x1b40): whatever
Here the fix is to adjust the regexp to match both formats.
Second, when following a DIE reference, point could end up on an
attribute instead. This happens when there is a zero-length attribute
with the same "offset" as the following DIE, like:
<12c5> DW_AT_GNU_all_call_sites: 1
<2><12c5>: Abbrev Number: 5 (DW_TAG_formal_parameter)
Here the fix is to search for the DIE by looking for the depth ("<2>"
in the example) as well.
I've bumped the internal version number to make it simpler to install
this using the Emacs package facility.

** <procfs.h> which only provides the structured /proc, definining
_STRUCTURED_PROC=1 and then including ...
** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based
/proc, but provides structured /proc if _STRUCTURED_PROC == 1.
* procfs and the large-file environment didn't go well together:
** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit
compilations when the large-file environment was active
(_FILE_OFFSET_BITS == 64).
** In both Solaris 11.4 and Illumos, this restriction was lifted for
structured /proc.
So one has to be careful always to define _STRUCTURED_PROC=1 when
testing for or using <sys/procfs.h> on Solaris. As the errors above
show, this isn't always the case in binutils-gdb right now.
Also one may need to disable large-file support for 32-bit compilations
on Solaris. config/largefile.m4 meant to do this by wrapping the
AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding
ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because
it neglects the _STRUCTURED_PROC part.
To make things even worse, since GCC 9 g++ predefines
_FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to
enable large-file support, this has no effect, breaking the gdb build.
This patch addresses all this as follows:
* All tests for the <sys/procfs.h> header are made with
_STRUCTURED_PROC=1, the definition going into the various config.h
files instead of having to make them (and sometimes failing) in the
affected sources.
* To cope with the g++ predefine of _FILE_OFFSET_BITS=64,
-U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had
been far easier to have just
#undef _FILE_OFFSET_BITS
in config.h, but unfortunately such a construct in config.in is
commented by config.status irrespective of indentation and whitespace
if large-file support is disabled. I found no way around this and
putting the #undef in several global headers for bfd, binutils, ld,
and gdb seemed way more invasive.
* Last, the applicability check in largefile.m4 was modified only to
disable largefile support if really needed. To do so, it checks if
<sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it
doesn't, the disabling only happens if gdb exists in-tree and isn't
disabled, otherwise (building binutils from a tarball), there's no
conflict.
What initially confused me was the check for $plugins here, which
originally caused the disabling not to take place. Since AC_PLUGINGS
does enable plugin support if <dlfcn.h> exists (which it does on
Solaris), the disabling never happened.
I could find no explanation why the linker plugin needs large-file
support but thought it would be enough if gld and GCC's lto-plugin
agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not
enough: lto-plugin uses the simple-object interface from libiberty,
which includes off_t arguments. So to fully disable large-file
support would mean also disabling it in libiberty and its users: gcc
and libstdc++-v3. This seems highly undesirable, so I decided to
disable the linker plugin instead if large-file support won't work.
The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both
Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to
predefined _FILE_OFFSET_BITS=64). Also regtested on
amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4),
x86_64-pc-linux-gnu and i686-pc-linux-gnu.

MIPS/LD: Set symtab's `sh_info' correctly for IRIX emulations
Correct ELF linker code so as to set the `sh_info' value of the static symbol table section according to the section symbols vs other symbols split where required by the selection of the IRIX compatibility mode for MIPS target. Add a `elf_backend_elfsym_local_is_section' hook for that purpose, returning TRUE if it is only STB_LOCAL/STT_SECTION symbols that are to be considered local for the purpose of this split rather than all STB_LOCAL symbols. We do it already in generic ELF code, and have done it since 1993, with the `elf_backend_sym_is_global' hook, affecting GAS and `objcopy', so these tools produce correct ELF output in the IRIX compatibility mode, however if such output is fed as input to `ld -r', then the linker's output is no longer valid for that mode. The relevant changes to generic ELF code are: commit |
