Avoid missing possible candidates due to the large address range of the free segment.
Eg,
48000000-49400000 r-xs 08000000 00:0f 39322841 segment1
7ffff2ec8000-7ffff2f49000 rw-p 00000000 00:00 0 segment2
7ffff6fae000-7ffff735c000 r-xp 00200000 08:02 11538515 /usr/local/sbin/php-fpm
original code will miss the opportunity between [7ffff2ec** - 7ffff2ec8000].

Instead of fixing up temporaries count in between observer steps, just apply the additional temporary in the two affected observer steps.
Closes GH-14018.
Older GCC versions (< 7.0) don't support the -Wno-implicit-fallthrough
compiler flag. This adds the flag conditionally in case some other
compiler will run into same issue.
Fixes GH-13330
Although the issue mentioned FreeBSD, this is a broader problem:
the current ARM64 code to load the TLS offset assumes a setup with
the non-default TLS model. This problem can also apply on some
configurations on other platforms.
Closes GH-11236.
Class constants are inherited to user classes without cloning. Thus, internal
class constants should not be persisted at all. Simply keep pointing to the
internal class constant.
Fixes GH-14109
Closes GH-14114
This regressed in 9a250cc9d6, which allowed static properties to get
overridden by a trait during inheritance. In particular, because of the
change to the loop in zend_update_parent_ce(), it's not guaranteed that
all indirects are after one another.
This means that during persisting the zvals of the static members table,
some static properties may be skipped. In case of the test code, this
means that the array in the trait will keep referring to the old, new
freed, stale value. To solve this, we check the type for IS_INDIRECT,
which is the same as what zend_persist_calc() is already doing anyway.
Since 2543e61aed we can check for IS_INDIRECT to see if it should be
persisted or not.
Closes GH-13794.
Inherited methods regardless of source must share the original runtime cache. Traits were missed.
This adds ZEND_ACC_TRAIT_CLONE to internal functions as well to allow easy distinction of these.
Moving the minimum base of the shared opcache memory to the second huge page to avoid a possible 0x0 base, which may cause all sorts of segfaults.
This is not a problem on most systems which have a mmap_min_addr which is non-zero, but e.g. WSL1 doesn't have a minimum mapping address.
autoconf/libtool generating code to test features missed `void` for
C calls prototypes w/o arguments.
Note that specific changes related to libtool have to be upstreamed.

This flag is supposed to go on the flags parameter, rather than prot. Moreover,
this flag is no longer needed because the JIT does not set RWX without ZTS, and
JIT+ZTS has been disabled on macOS with Apple Silicon.
Closes GH-13638
