[SystemZ][z/OS] add back headers needed for strnlen, autoconversion

[llvm] Remove unused includes (NFC) (#142733)

2025-06-04T19:30:52+00:00

These are identified by misc-include-cleaner.  I've filtered out those
that break builds.  Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.

[YAML] Don't validate `Fill::Size` after error (#123280)

2025-01-23T17:52:34+00:00

Size is required, so we don't know if it's in
uninitialized state after the previous error.

Triggers msan on llvm/test/tools/yaml2obj/ELF/custom-fill.yaml NOSIZE
test.

We have `Fill` Section with Pattern, but no size. Before the fix it
produced error:
```
YAML:169:5: error: missing required key 'Size'
  - Type:    Fill
    ^
YAML:169:5: error: "Size" can't be 0 when "Pattern" is not empty
  - Type:    Fill
```

The same applies to `MachOYAML::Section` fields `content` and `size`.
However `MachOYAML::Section` matches size first, so on error,
content is not set anyway. Added error checking just in case.

[SystemZ][z/OS] Add missing strnlen function for z/OS to fix build failures (#75339)

2023-12-13T18:13:53+00:00

This patch adds strnlen to the zOSSupport.h file to fix build failures in multiple files.

[llvm-nm][MachO] Add support for `MH_FILESET`

2023-09-05T16:51:12+00:00

Support printing of symbols for MachO of `MH_FILESET` type.
This is achieved by extending `dumpSymbolNamesFromObject`
to encompass fileset handling, and including an offset in
`MachOObjectFile` class to locate embedded MachO headers.

[NFC][TargetParser] Replace uses of llvm/Support/Host.h

2023-02-10T09:59:46+00:00

The forwarding header is left in place because of its use in
`polly/lib/External/isl/interface/extract_interface.cc`, but I have
added a GCC warning about the fact it is deprecated, because it is used
in `isl` from where it is included by Polly.

[ObjectYAML] Basic support for chained fixups.

2022-11-11T18:15:30+00:00

Add basic binary support for chained fixups. This allows basic tests
with chained fixups without trying to create a format for them until the
work on the Object library is considered finished.

[ObjectYAML] Support for basic data in code.

2022-10-04T16:36:27+00:00

This is a split of D134250.

Supports for parsing and dumping the LC_DATA_IN_CODE contents (as binary
data).

This allows more complete testing of llvm-objdump in D133974.

[llvm] Teach LLVM about filesets

2022-08-24T16:33:45+00:00

Teach LLVM about filesets. Filesets were added in macOS 11 (Big Sur) to
combine multiple Mach-O files. They introduce a new load command
(LC_FILESET_ENTRY) consisting of a fileset_entry_command.

  struct fileset_entry_command {
      uint32_t     cmd;        /* LC_FILESET_ENTRY */
      uint32_t     cmdsize;    /* includes entry_id string */
      uint64_t     vmaddr;     /* memory address of the entry */
      uint64_t     fileoff;    /* file offset of the entry */
      union lc_str entry_id;   /* contained entry id */
      uint32_t     reserved;   /* reserved */
  };

This patch teaches LLVM about the new load command and the corresponding
data.
