This is a false positive. The cycle detection code stops at 10.000
iterations. Instead of stopping at a fixed amount, make it more robust
by implementing Floyd's cycle detection algorithm.
Closes GH-12954.
`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers. This is misleading, so let's use a
C99 integer instead.
On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical. This change is only about code readability.
To make sure this is automatically detectable as a PHP bug,
e.g. during fuzzing. Also dump the current opcodes/SSA as we may
no longer reach a following dump.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
This only moves the files, adjusts the build system, exports APIs
and does minor fixups to make sure the code builds.
This does not yet try to make the optimizer usable independently
of opcache.
Closes GH-6642.
