2023-01-20Add testcase ld-elf/merge4Michael Matz4-0/+55
to check a situation that once failed with the new section merging when it mishandled offsets pointing into alignment padding in mergable string sections (i.e. pointing to zeros). It made bootstrap.exp fail but that depends on many factors to actually go wrong so this is a more explicit variant of it.
2023-01-20arm32: Fix rodata-merge-mapMichael Matz2-4/+4
the test expects a second, but useless, $d mapping symbol for the partially merged section, and specifically disallows one for the completely merged section. The new merging algorithm makes it so that also the partially merged sections are conceptually SEC_EXCLUDED, except the first merge section (e.g. as if the very first object file already contains all strings). So that second mapping symbol is now missing. It never was needed anyway. So, adjust the test.
2023-01-16Correct ld-pe/aarch64.d test outputAlan Modra1-12/+12
"foo" is at 0x2010. This corrects the expected output for .long and .word referencing foo, showing a problem with relocation handling. * testsuite/ld-pe/aarch64.d: Correct expected output.
2023-01-12ld/testsuite: Adjust for ELF_MAXPAGESIZE 0x1000Hans-Peter Nilsson7-29/+32
Many tests reflect a setting of ELF_MAXPAGESIZE to 64 KiB. With ELF_MAXPAGESIZE changed to 4 KiB, layout is sometimes different and symbols end up in other places. Avoid churn and regexpification of old test patterns by passing the max-page-size setting active at the time. ld/testsuite: * testsuite/ld-arm/arm-elf.exp, testsuite/ld-arm/non-contiguous-arm2.d, testsuite/ld-arm/non-contiguous-arm3.d, testsuite/ld-arm/non-contiguous-arm5.d, testsuite/ld-arm/non-contiguous-arm6.d, testsuite/ld-arm/thumb-plt-got.d, testsuite/ld-arm/thumb-plt.d: Pass -z max-page-size=0x10000 explicitly to test that rely on that value in output-matching patterns.

2023-01-04Avoid unaligned pointer reads in PEP .idata sectionMark Harmstone1-0/+1
This is something I discovered when working on aarch64, though it's relevant to x86_64 too. The PE32+ imports are located in the .idata section, which starts off with a 20-byte structure for each DLL, containing offsets into the rest of the section. This is the Import Directory Table in https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, which is a concatenation of the .idata$2 sections. This is then followed by an 20 zero bytes generated by the linker script, which calls this .idata$3. After this comes the .idata$4 entries for each function, which the loader overwrites with the function pointers. Because there's no padding between .idata$3 and .idata$4, this means that if there's an even number of DLLs, the function pointers won't be aligned on an 8-byte boundary. Misaligned reads are slower on x86_64, but this is more important on aarch64, as the e.g. `ldr x0, [x0, :lo12:__imp__func]` the compiler might generate requires __imp__func (the .idata$4 entry) to be aligned to 8 bytes. Without this you get IMAGE_REL_ARM64_PAGEOFFSET_12L overflow errors.

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.
