bc3512c1d6 Fix various update_opN_const issues 2015-11-07 17:45:26 +01:00
Nikita Popov
9da456655c Refactor update_op2_const
Combines both switches into one, to avoid having to maintain the same
opcode list twice. This also makes most of the bugs fixed by the next
commit pretty obvious.

No functional change here.

99d818f1e9 Don't propagate into ops that error on non-string
To properly support this make update_opN_const fallible -- they
are not always called through replace_with_const.

ffb5d0aca3 Implemented file_cache_fallback mechanism
which is essential as an attempt to fix the "failed to reattach"
error on Windows. If file_cache is enabled, Opcache will
automaticaly switch to file_cache_only mode in the case a process
failed to map the shared segment at the required address. The
important small part of the SHM will still be mapped, which
allows information exchange between normal processes using SHM
and those using the fallback mechanism.

This is based on Dmitry's, Matt's and mine ideas. So many thanks for
support!

Other platforms than listed in the checks are not supported since
PHP 5.5. We also won't need these checks for a while, so can simplify.

669f0b39b1 Added an experemental ability to move PHP code pages (PHP TEXT segment) into HUGE pages.
PHP should be configured and built with --enable-huge-code-pages, OS should be configured to provide huge pages.
It's possible to enable/disable this future in php.ini through opcache.enable_huge_code_pages=0/1.
The feature was tested on Linux and provided 2% improvement on real-life apps, because of 2-3 times reduction in number of iTLB misses.

68185bafbe opcache: Patch SSE based fast_memcpy() implementation
Use _mm_store_si128() instead of _mm_stream_si128(). This ensures that copied memory
is preserved in data cache, which is good as the interpretor will start to use this
data without the need to go back to memory. _mm_stream* is intended to be used for
stores where we want to avoid reading data into the cache and the cache pollution;
in our scenario it seems that preserving the data in cache has a positive impact.

Tests on WordPress 4.1 show ~1% performance increase with fast_memcpy() in place
versus standard memcpy() when running php-cgi -T10000 wordpress/index.php.

I also updated SW prefetching on target memory but its contribution is almost negligible.
The address to be prefetched will be used in a couple of cycles (at the next iteration)
while the data from memory will be available in >100 cycles.
