2023-01-02obsolete target tidyAlan Modra10-31/+6
Delete a few files only used for obsolete targets, and tidy config, xfails and other pieces of support specific to those targets. And since I was editing target triplets in test files, fix the nm alpha-linuxecoff fails.

2022-12-31ld: Handle extended-length data structures in PDB typesMark Harmstone6-28/+344
A few fixes to minor issues I've discovered in my PDB patches. * If sizes or offsets are greater than 0x8000, they get encoded as extended values in the same way as for enum values - e.g. a LF_ULONG .short followed by a .long. * I've managed to coax MSVC to produce another type, LF_VFTABLE, which is seen when dealing with COM. I don't think LLVM emits this. Note that we can't just implement everything in Microsoft's header files, as most of it is obsolete. * Fixes a stupid bug in the test program, where I was adding an index to a size. The index was hard-coded to 0, so this didn't cause any actual issues.

2022-12-21enable-non-contiguous-regions warningsAlan Modra7-14/+40
The warning about discarded sections in elf_link_input_bfd doesn't belong there since the code is dealing with symbols. Multiple symbols in a discarded section will result in multiple identical warnings about the section. Move the warning to a new function in ldlang.c. The patch also tidies the warning quoting of section and file names, consistently using `%pA' and `%pB'. I'm no stickler for one style of section and file name quoting, but they ought to be consistent within a warning, eg. see the first one fixed in ldlang.c, and when a warning is emitted for multiple targets they all ought to use exactly the same format string to reduce translation work. elf64-ppc.c loses the build_one_stub errors since we won't get there before hitting the fatal errors in size_one_stub. bfd/ * elflink.c (elf_link_input_bfd): Don't warn here about discarded sections. * elf32-arm.c (arm_build_one_stub): Use consistent style in --enable-non-contiguous-regions error. * elf32-csky.c (csky_build_one_stub): Likewise. * elf32-hppa.c (hppa_build_one_stub): Likewise. * elf32-m68hc11.c (m68hc11_elf_build_one_stub): Likewise. * elf32-m68hc12.c (m68hc12_elf_build_one_stub): Likewise. * elf32-metag.c (metag_build_one_stub): Likewise. * elf32-nios2.c (nios2_build_one_stub): Likewise. * elfnn-aarch64.c (aarch64_build_one_stub): Likewise. * xcofflink.c (xcoff_build_one_stub): Likewise. * elf64-ppc.c (ppc_size_one_stub): Likewise.

2022-11-30section-select: Fix exclude-file-3Michael Matz2-4/+7
this testcase wasn't correctly testing everything, it passed, even though sections from an excluded file were included. Fixing this reveals a problem in the new section selector. This fixes that as well.
2022-11-30section-select: Remove unused codeMichael Matz2-509/+1
walk_wild_file, hence walk_wild_section and walk_wild_section_handler aren't called with the prefix tree. Hence initialization of the latter and all potential special cases for it aren't used anymore. That also removes the need to handler_data[] and some associated helper functions. So, remove all of that.
2022-11-30section-select: Implement a prefix-treeMichael Matz2-33/+316
Now that we have a list of potentially matching sections per wild statement we can actually pre-fill that one by going once over all input sections and match their names against a prefix-tree that points to the potentially matching wild statements. So instead of looking at all sections names for each glob for each wild statement we now look at the sections only once and then only check against those globs that have a possibility of a match at all (usually only one or two). This pushes the whole section selection off the profiles.
2022-11-30section-select: Completely rebuild matchesMichael Matz1-0/+22
The check_relocs callback (and others) might have created new section behind our back and some of them (e.g. on powerpc the "linker stubs" .got) need to come in front of all others, despite being created late (a symptom would be "TOC opt*" failing on powerpc). This resets all section matches before updating for newly created sections (i.e. completely rebuilds the matches).
2022-11-30section-select: Lazily resolve section matchesMichael Matz2-1/+99
and remember the results. Before this the order of section matching is basically: foreach script-wild-stmt S foreach pattern P of S foreach inputfile I foreach section S of I match S against P if match: do action for S And this process is done three or four times: for each top-level call to walk_wild() or wild(), that is: check_input_sections, lang_gc_sections, lang_find_relro_sections and of course map_input_to_output_sections. So we iterate over all sections of all files many many times (for each glob). Reality is a bit more complicated (some special glob types don't need the full iteration over all sections, only over all files), but that's the gist of it. For future work this shuffles the whole ordering a bit by lazily doing the matching process and memoizing results, trading a little memory for a 75% speedup of the overall section selection process. This lazy resolution introduces a problem with sections added late that's corrected in the next patch.

2022-11-28Only use wild_sort_fastMichael Matz6-178/+163
there's no reason why the tree-based variant can't always be used when sorting is required, it merely needs to also support filename sorting and have a fast path for insertion at end (aka rightmost tree leaf). The filename sorting isn't tested anywhere and the only scripttempl that uses it is avr (for 'SORT(*)(.ctors)'), and I believe even there it was a mistake. Either way, this adds a testcase for filename sorting as well. Then the non-BST based sorting can be simplified to only support the fast case of no sorting required at all (at the same time renaming the two variants to _sort and _nosort).
2022-11-28Special case more simple patternsMichael Matz2-33/+95
fnmatch is slow, so avoiding it in more cases is good. This implements a more generic version of match_simple_wild which needs some pre-processing of patterns. In particular it supports patterns of the form PREFIX*SUFFIX (where all parts are optional), i.e. a super set of what's handled now. Most section matchers of this form and hence don't need any calls to fnmatch anymore. We retain the implementation of match_simple_wild for the filename matchers (they aren't called often enough to matter).

2022-11-15bfd: linker: merge .sframe sectionsIndu Bhagat23-7/+342
The linker merges all the input .sframe sections. When merging, the linker verifies that all the input .sframe sections have the same abi/arch. The linker uses libsframe library to perform key actions on the .sframe sections - decode, read, and create output data. This implies buildsystem changes to make and install libsframe before libbfd. The linker places the output .sframe section in a new segment of its own: PT_GNU_SFRAME. A new segment is not added, however, if the generated .sframe section is empty. When a section is discarded from the final link, the corresponding entries in the .sframe section for those functions are also deleted. The linker sorts the SFrame FDEs on start address by default and sets the SFRAME_F_FDE_SORTED flag in the .sframe section. This patch also adds support for generation of SFrame unwind information for the .plt* sections on x86_64. SFrame unwind info is generated for IBT enabled PLT, lazy/non-lazy PLT. The existing linker option --no-ld-generated-unwind-info has been adapted to include the control of whether .sframe unwind information will be generated for the linker generated sections like PLT. Changes to the linker script have been made as necessary.

2022-11-14pru: bfd: Correct default to no execstackDimitar Dimitrov1-0/+1
Data and instruction memories are strictly separated, so it is not possible to execute instructions from the stack memory on PRU. I don't see any difference in testsuite results with or without this change. bfd/ChangeLog: * elf32-pru.c (elf_backend_default_execstack): Define as 0. ld/ChangeLog: * testsuite/ld-elf/elf.exp (target_defaults_to_execstack): Return 0 for pru.
