2021-02-16x86: have preprocessor expand macrosJan Beulich3-11/+11
There's no point having i386-gen's set_bitfield() to handle any aliases, now that we pass the opcode table through the C preprocessor anyway.

nds32_elf_get_relocated_section_contents uses nds32_get_section_contents to read sections contents, but nds32_get_section_contents has the wrong behaviour as it calls bfd_malloc_and_get_section.

2021-02-14objdump: don't add an extra entry to syms arrayAlan Modra2-28/+32
Space for a NULL is there in every backend bfd_get_symtab_upper_bound or bfd_get_dynamic_symtab_upper_bound when the symbol count is non-zero, and placed as a terminator by bfd_canonicalize_symtab. Many backends even return a single NULL entry array for zero symbol count, and while there are a few that return a NULL array for no symbols, that case is handled fine in objdump. So don't have objdump add yet another NULL entry. * objdump.c (slurp_symtab): Don't add an extra entry for NULL to the symbol array. (slurp_dynamic_symtab): Likewise. (dump_bfd): Formatting.

2021-02-14ld testsuite: change unresolved to unsupported/failAlan Modra43-209/+220
"unresolved" as a test result means runtest returns an error, which can be confusing when there is no apparent error unless you look in .log files. In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved. Which is no more worthy of an error than when lacking a C compiler entirely. * testsuite/ld-cdtest/cdtest.exp, * testsuite/ld-checks/checks.exp, * testsuite/ld-elf/binutils.exp, * testsuite/ld-elf/compress.exp, * testsuite/ld-elf/dwarf.exp, * testsuite/ld-elf/exclude.exp, * testsuite/ld-elf/frame.exp, * testsuite/ld-elf/indirect.exp, * testsuite/ld-elf/linux-x86.exp, * testsuite/ld-elf/sec-to-seg.exp, * testsuite/ld-elf/tls_common.exp, * testsuite/ld-elfcomm/elfcomm.exp, * testsuite/ld-elfvers/vers.exp, * testsuite/ld-elfvsb/elfvsb.exp, * testsuite/ld-elfweak/elfweak.exp, * testsuite/ld-ifunc/binutils.exp, * testsuite/ld-mips-elf/mips-elf-flags.exp, * testsuite/ld-misc/defsym.exp, * testsuite/ld-mn10300/mn10300.exp, * testsuite/ld-plugin/lto.exp, * testsuite/ld-plugin/plugin.exp, * testsuite/ld-scripts/align.exp, * testsuite/ld-scripts/assert.exp, * testsuite/ld-scripts/crossref.exp, * testsuite/ld-scripts/defined.exp, * testsuite/ld-scripts/extern.exp, * testsuite/ld-scripts/log2.exp, * testsuite/ld-scripts/map-address.exp, * testsuite/ld-scripts/phdrs.exp, * testsuite/ld-scripts/phdrs2.exp, * testsuite/ld-scripts/script.exp, * testsuite/ld-scripts/section-flags.exp, * testsuite/ld-scripts/sizeof.exp, * testsuite/ld-scripts/weak.exp, * testsuite/ld-selective/selective.exp, * testsuite/ld-sh/sh.exp, * testsuite/ld-shared/shared.exp, * testsuite/ld-srec/srec.exp, * testsuite/ld-tic6x/tic6x.exp, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-undefined/weak-undef.exp, * testsuite/lib/ld-lib.exp: Don't use unresolved except after perror.

2021-02-13sim: testsuite: push $arch out to targetsMike Frysinger73-45/+274
This is needed to move to automake & its dejagnu-provided logic, and eventually by the unified sim logic. The $arch is used only to figure out which `run` program to use when running tests, and as we move to a single top-level build, we can delete this and use sim/run directly.

2021-02-13config/debuginfod: do not include pkg.m4 directlyMike Frysinger6-3/+14
Any code using AC_DEBUGINFOD from this dir is using -I../config when running aclocal, so an explicit include on pkg.m4 is unnecessary: aclocal will find the pkg.m4 in this dir just as easily. This is seen in the only two dirs that use AC_DEBUGINFOD (binutils & gdb) as their aclocal.m4 already has m4_include on config m4 files. The include as written only works if aclocal is run on a dir that is at the same level of config/. Any other depth will fail. ./ |-- config/ |-- binutils/ # works |-- gdb/ # works `-- sim/ # works `-- <port>/ # fails It fails even if AC_DEBUGINFOD itself isn't used: sim/bfin/ $ aclocal -I../../config aclocal-1.15: error: ../../config/debuginfod.m4:8: file '../config/pkg.m4' does not exist

2021-02-12binutils testsuite: replace unresolved with unsupportedAlan Modra5-40/+50
You'd think "unresolved" would be correct for an objcopy test when the assembler refuses to assemble one of our source files. After all, the test of objcopy hasn't been run. However, "unresolved" results in runtest returning with an error status. If instead we report "unsupported", runtest returns success. Which is a little less confusing to a user who doesn't see any errors reported unless they look in log files. * testsuite/binutils-all/objcopy.exp: Report "unsupported" when gas or ld fails to build a testcase rather than "unresolved".

2021-02-12gas testsuite: adjust recently added tests for hppaAlan Modra6-12/+21
Some hppa gas targets treat anything starting in the first column as a label, so directives can't start there. Also, binutils_assemble and run_dump_test cleverly edit test source to suit the hppa .comm directive which has a different syntax to most targets. The editing means we can't match source file names in dumps. Finally, hppa gas complains if instructions are emitted without a ".text" or similar directive. * testsuite/gas/all/pr27381.err: Don't match source file name. * testsuite/gas/all/pr27381.s: Don't start directive in first column. * testsuite/gas/all/pr27384.err: Don't match source file name.

2021-02-11gdb: change 'maint info section' to use command optionsAndrew Burgess7-107/+213
The 'maintenance info sections' command currently takes a list of filters on the command line. It can also accept the magic string 'ALLOBJ' which acts more like a command line flag, telling the command to print information about all objfiles. The manual has this to say about the options and filters: ... In addition, 'maint info sections' provides the following command options (which may be arbitrarily combined): ... Implying (to me at least) that I can do this: (gdb) maint info sections ALLOBJ READONLY to list all the read-only sections from all currently loaded object files. Unfortunately, this doesn't work. The READONLY filter will work, but ALLOBJ will not be detected correctly. It would be fairly simple to fix the ALLOBJ detection. However, I dislike this mixing of command options (ALLOBJ) with command data (the filters, e.g. READONLY, etc). As this is a maintenance command, so not really intended for end users, I think we can be a little more aggressive in "fixing" the option parsing. So that's what I do in this commit. The ALLOBJ mechanism is replaced with a real command option (-all-objects). The rest of the command operates just as before. The example above would now become: (gdb) maint info sections -all-objects READONLY The manual has been updated, and I added a NEWS entry to document the change. gdb/ChangeLog: * NEWS: Mention changes to 'maint info sections'. * maint.c (match_substring): Return a bool, fix whitespace issue.

2021-02-11gdb: 'maint info sections' - handle the no executable caseAndrew Burgess4-63/+105
The 'maint info sections' command is split into two blocks or work, first if there's an executable then the sections from the executable, and optionally all other loaded object files are printed. Then all the sections from any core file are printed. I ran into a situation where (for various reasons) I wasn't using a main executable. Instead I connected to a remote target and used add-symbol-file. This allowed me to debug an image that was already loaded on the remote system. Unfortunately, when I tried to use 'maint info sections' I saw nothing. The reason is that the loop over all object files is hidden behind a check that we have a main executable. This commit removes this check and merges together some duplicate code. I also (I think) made the output of this command cleaner. Here is the original output of 'maint info sections': Exec file: `/tmp/hello.x', file type elf64-x86-64.

The executable now only gets a single header line. The header line for the additional object files is no longer indented as it was before, and the line is laid out in a similar style to the main executable line (with quotes and file type information). And of course, the biggest change. If GDB is started with no executable, but then the user does 'add-symbol-file ....' followed by 'maint info sections ALLOBJ', previously they got nothing, now they get: Object file: `/tmp/hello.x', file type elf64-x86-64.

2021-02-11gdb/testsuite: split 'maint info sections' tests to a new fileAndrew Burgess3-87/+135
The next couple of patches are going to add more tests for the 'maint info sections' command. Rather than try to jam these tests into the already quite long gdb.base/maint.c, this commit moves all of the tests for 'maint info sections' into a new file. I've updated the tests to make use of some newer testsuite constructs, like -wrap and $gdb_test_name for gdb_test_multiple, but otherwise the tests should not have changed with this commit. gdb/testsuite/ChangeLog: * gdb.base/maint-info-sections.exp: New file, content is moved from gdb.base/maint.exp and cleaned up to use latest testsuite techniques. * gdb.base/maint.exp: Tests moved out to gdb.base/maint-info-sections.exp.
2021-02-11gdb: add obj_section function to bound_minimal_symbolAndrew Burgess6-4/+22
Add a new obj_section function to bound_minimal_symbol, this just calls obj_section on the contained minimal_symbol passing in the contained objfile. This allows some minor code simplification in a few places. There should be no user visible changes after this commit. gdb/ChangeLog: * breakpoint.c (resolve_sal_pc): Make use of bound_minimal_symbol::obj_section. * maint.c (maintenance_translate_address): Likewise. * minsyms.c (minimal_symbol_upper_bound): Likewise. * minsyms.h (struct bound_minimal_symbol) <obj_section>: New member function. * printcmd.c (info_address_command): Make use of bound_minimal_symbol::obj_section.

2021-02-11PR27291, integer overflow in bfd_get_section_contentsAlan Modra2-4/+9
Makes the code a little more elegant too. Note that the unsigned overflow reported here is well defined so this patch doesn't fix any real problem. PR 27291 * section.c (bfd_get_section_contents): Avoid possible overflow when range checking offset and count. (bfd_set_section_contents): Likewise.
