Fixed bug #80046

We already protect against optimizing away loop frees in DFA pass,
but not in block pass.

Fix handling of non-final loop var free in sccp

We only need to preserve the FE_FREE that marks the end of the
loop range. Skip FE_FREEs with the FREE_ON_RETURN flag.

ZEND_DECLARE_ANON_CLASS doesn't need to skip anything now. It's immediatelly followed by ZEND_NEW.

Register class before fetching parent

We want the class declaration to be available while compiling the
parent class.

Fixed CFG construction for SWITCH opcodes

ZEND_COMPILE_EXTENDED_INFO split Currently a tool may not decide between debugging and profiling behaviour: We split ZEND_COMPILE_EXTENDED_INFO into ZEND_COMPILE_EXTENDED_FCALL and ZEND_COMPILE_EXTEN

ZEND_COMPILE_EXTENDED_INFO split Currently a tool may not decide between debugging and profiling behaviour: We split ZEND_COMPILE_EXTENDED_INFO into ZEND_COMPILE_EXTENDED_FCALL and ZEND_COMPILE_EXTENDED_STMT We define ZEND_COMPILE_EXTENDED_INFO as ZEND_COMPILE_EXTENDED_STMT|ZEND_COMPILE_EXTENDED_FCALL

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

Implement single-pass live range calculation

Instead of interleaving creation of live-ranges with the main
compiler code, compute them in a separate pass over the opcodes
as part of pass_two. Additionally, do not keep live ranges
synchronized during optimization in opcache and instead use the
same mechanism to recompute them after optimization.

CFG construction: Avoid code duplication

These code for those two cases is the same nowadays, so merge them.

Moved "zval.u2.cache_slot" into free room of "zend_op"

Changed CATCH instruction format (extended_value moved into op2, op2 into result, result into extended_value)

Change FETCH/ISSET instruction modifiers:
- Get rid of ZEND_ISEMPTY and ZEND_ISSET_ISEMPTY_MASK. Use just single ZEND_ISSET bit to make distinct between isset() and empty()
- Use ZEND_FETCH_G

Cleanup cfg flags & Added ZEND_FUNC_HAS_EXTENED_INFO

Split CFG after RECV independently from ZEND_ACC_HAS_TYPE_HINTS flag.

Fixed wrong edges_count re-calculation.

Separate ISSET_ISEMPTY_CV/UNSET_CV from ISSET_ISEMPTY_VAR/UNSET_VAR

Fixed CFG/SSA construction (avoid multiple identical predecessors)
