php_mergesort() isn't being used for anything, and hasn't been for
a long time. Even if we wanted to use a stable sort, this isn't
the implementation we'd use...
This reverts commit edccf32f7f.
This was reported to cause issues for as yet unknown reasons in
bug #78769. As this was intended as code cleanup, revert this from
7.4 at least. May reapply it to master later.
These were checking whether the instruction set is supported by
the host CPU, however they were only used to condition on whether
this instruction set is targeted at all. It would still use dynamic
dispatch (e.g. based on ifunc resolvers) to select the actual
implementation. Whether the target is guaranteed to support the
instruction set without dispatch is determined based on pre-defined
macros like __SSE2__.
This removes the configure-time builtin cpu checks to remove
confusion. Additionally this allows targeting an architecture that
is newer than the host architecture.
C99 no longer has implicit function declarations and implicit ints.
Current GCC versions enable them as an extension, but this will
change in a future GCC version.
When building PHP outside of the source tree:
mkdir custom-build-dir
cd custom-build-dir
../path/to/php-src/configure
The directories need to be manually created including the pear directory
so the pear installation PHAR file doesn't need to be downloaded from
the remote location.
Closes GH-4639
This was a left over for supporting old code in PHP extensions out there.
Check is not needed anymore since this is part of C89+ standard.
Closes GH-4445
- yp_get_default_domain was part of ext/yp
- functions checks produce HAVE_function_name symbols. These checks are
currently not used in php-src neither in the extensions out there.
- Removed symbols because they are not used in the code:
- HAVE_GCVT
- HAVE_PUTENV
- HAVE_PUTENV
- HAVE_SETVBUF
- HAVE_TEMPNAM
- HAVE_SIN (sin is also defined in C89 standard)
- HAVE_SETSOCKOPT
- HAVE_LOCKF
- HAVE_ISASCII
- HAVE_YP_GET_DEFAULT_DOMAIN (and other yp extension related unused checks)
- HAVE_LINK
- HAVE_USLEEP is already defined in Windows configuration header
- HAVE_LIBBIND has not been used in php-src for a while anymore
- HAVE_GETHOSTNAME is duplicated in Windows configuration header
Closes GH-4417
The undef PTHREADS converts to define if thread safety is configured.
This step is already done by pthreads m4 macros from TSRM so this now
removes duplicated PTHREADS defines from php_config.h.
