[LLVM] [Support] Disable `ioctl()` terminal size check on Solaris (#144600)

2025-06-17T20:44:02+00:00

#143514 broke the `clang-solaris11-sparcv9` bot; from what I can tell
that’s Solaris and according to `SolarisTargetInfo::getOSDefines`, the
macro `__sun__` should be defined on Solaris, so check for that and
don’t try to query the terminal size if it is defined.

Not sure this is the best solution but hopefully it fixes the bot.

[LLVM] [Support] Query the terminal width using `ioctl()` (#143514)

2025-06-17T13:03:37+00:00

On unix systems, we were trying to determine the terminal width using
the `COULMNS` environment variable. Unfortunately, `COLUMNS` is not 
exported by all shells and thus not available on some systems.

We were previously using `ioctl()` for this; fall back to doing so if `COLUMNS`
does not exist or does not store a positive integer.

This essentially reverts a3eb3d3d92d037fe3c9deaad87f6fc42fe9ea766 and
parts of https://reviews.llvm.org/D61326.

For more information, see #139499.

Fixes #139499.

[Support] Fix building on FreeBSD and OpenBSD (#127005)

2025-02-13T03:55:22+00:00

Fix building after a6f7cb54d3c268ea4748a0ff783b4b030c3195d9.

Check for the function getauxval() instead of just the sys/auxv.h
header.

[Support] Prefer AUX vector for page size (#126863)

2025-02-13T00:39:49+00:00

Prefers the page size to come from the AUX vector, `getpagesize` is
removed from POSIX.1-2001. Also throws in a couple asserts to ensure the
page size is a valid value.

[NFC] Add explicit #include llvm-config.h where its macros are used. (#106621)

2024-08-30T07:35:06+00:00

Without these explicit includes, removing other headers, who implicitly
include llvm-config.h, may have non-trivial side effects.
