[SystemZ][z/OS] Refactor AutoConvert more (#143955)

2025-06-13T11:00:36+00:00

This patch removes the C++
disablezOSAutoConversion,enablezOSAutoConversion declarations and also
updates Path.inc to use the common function.

[NFC][ADT/Support] Add {} for else when if body has {} (#140758)

[llvm] Add managarm support (#138854)

2025-05-09T02:37:17+00:00

This PR is part of a series to upstream managarm support, as laid out in
the
[RFC](https://discourse.llvm.org/t/rfc-new-proposed-managarm-support-for-llvm-and-clang-87845/85884/1).
This PR is a follow-up to #87845.

The intention here is to add the managarm target to the LLVM support
lib, in preparation for a follow-up that would add the missing clang
driver bits.

[NFC] Remove redundant `sys/file.h` header. (#124684)

2025-01-28T16:50:24+00:00

Closes #124652.

This header was introduced in
https://github.com/llvm/llvm-project/commit/536736995bf5d073853c7e884968c9847b4ae64d,
but it appears that including only `fnctl.h` should be enough.
Hopefully, this patch will not cause build issues on other Unix
platforms.

[CMake] Remove HAVE_DLFCN_H and HAVE_DLADDR (#123879)

2025-01-22T16:15:10+00:00

It is sufficient to just use `HAVE_DLOPEN`.

[CMake] Remove some always-true HAVE_XXX_H

2025-01-15T17:53:21+00:00

These are unneeded even on AIX, PURE_WINDOWS, and ZOS (per #104706)

* HAVE_ERRNO_H: introduced by 1a93330ffa2ae2aa0b49461f05e6f0d51e8443f8 (2009) but unneeded.
  The guarded ABI is unconditionally used by lldb.
* HAVE_FCNTL_H
* HAVE_FENV_H
* HAVE_SYS_STAT_H

[hurd] Fix accessing f_type field of statvfs (#71851)

2024-09-09T13:53:33+00:00

f4719c4d2cda ("Add support for GNU Hurd in Path.inc and other places")
made llvm use an internal __f_type name for the f_type field (which it
is not supposed to since accessing double-underscore names is explicitly
not supported by standards). In glibc 2.39 this field was renamed to
f_type so application can now access the field as the standard says.

[NFC][SystemZ][z/OS] Rename autoconversion-related functions to be less generic (#107399)

2024-09-05T17:25:06+00:00

This patch renames the functions in AutoConvert.h/cpp to have a less
generic name because they are z/OS specific.

[Support] Don't use StringRef::equals in Path.inc (#98839)

2024-07-14T21:50:21+00:00

The removal of StringRef::equals in
3fa409f2318ef790cc44836afe9a72830715ad84 broke the
[Solaris/sparcv9](https://lab.llvm.org/buildbot/#/builders/13/builds/724)
and
[Solaris/amd64](https://lab.llvm.org/staging/#/builders/94/builds/5176)
buildbots:
```
In file included from /vol/llvm/src/llvm-project/git/llvm/lib/Support/Path.cpp:1200:
/vol/llvm/src/llvm-project/git/llvm/lib/Support/Unix/Path.inc:519:18: error: no member named 'equals' in 'llvm::StringRef'
  519 |   return !fstype.equals("nfs");
      |           ~~~~~~ ^
```

Fixed by switching to `operator!=` instead.

Tested on sparcv9-sun-solaris2.11 and amd64-pc-solaris2.11.

[Support] Report EISDIR when opening a directory (#79880)

2024-04-17T21:56:42+00:00

The test `llvm/unittests/Support/CommandLineTest.cpp` that handles
errors in expansion of response files was previously disabled for AIX.
Originally the code was dependent on `read` returning `EISDIR` which
occurs on platforms such as Linux. However, other platforms such as AIX
allow use of `read` on file descriptors for directories. This change
updates `readNativeFile` to produce `EISDIR` on AIX and z/OS when used
on a directory (instead of relying on the call to `read` to do so).
