When system is detected as big endian this enables the TSRM Local
Storage static cache with the ZEND_ENABLE_STATIC_TSRMLS_CACHE
compilation flag. Previously it was enabled only on little endian
systems.
Turns out that the instrumentation added for gcov can change inlining
decisions of the compiler, which results in a mismatch between the
profile data CFG and the actual generated CFG between compiles.
There are two functions that suffer from this issue:
1. _PHP_XXH3_Init: Removing the inline hint fixes this one. In fact,
always inlining this makes no sense as there's no real opportunity
for specialising. It just bloats the binary and increases I$ pressure.
So besides fixing this issue it's beneficial on its own to drop the
attribute.
2. PHP_XXH3_128_Final: Sometimes XXH128_canonicalFromHash gets inlined
and sometimes not. Make sure it gets always inlined.
Closes GH-18814.
To match other capitalized strings like `ZEND_STR_UNKNOWN_CAPITALIZED` and
`ZEND_STR_ARRAY_CAPITALIZED`. Since this known string was only added in PHP
8.4, no backwards compatibility alias is needed.
When functions' or class methods' availability is based on some preprocessor
condition, the generated arginfo header files wrap the declarations in the
preprocessor `#if` conditional blocks, one per declaration, even if they are in
the same conditional block based on comments in the stub file. Instead of
having multiple conditional blocks one after the other with the same condition,
combine them into a single conditional block.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
This fixes the build for amd64 platforms that do not have
`HAVE_FUNC_ATTRIBUTE_TARGET`, specifically Alpine/Musl as of now.
Closes GH-15384.
Related to GH-15312.
The 3rd argument of the PHP_NEW_EXTENSION can be "shared" or "yes" to
mark the extension as shared, or anything else to mark that extension as
not shared. This syncs the argument values across the build system to be
"no" as in other always-enabled extensions.
When building in out-of-source directory, instead of creating these
build directories right away, this appends them to the list and creates
them at the end of configure phase. These don't need to be created
immediately as no files are generated in these extensions before the
configure phase is finished.
Also, the PHP_ADD_BUILD_DIR is moved after the PHP_NEW_EXTENSION when
the more common $ext_builddir variable is available (the ext/<extension>
isn't available when building with phpize).
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
