* 0003-Patch-utilities-and-data-structure-to-be-able-to-gen.patch
|
||||
A PHP specific patch to patch utilities and data structure to be able to generate smaller lookup tables.
|
||||
This patch won't be upstreamed because it breaks generality of those data structures, i.e. it only works
|
||||
because we only use it for character encoding.

|
||||
* 0004-Remove-unused-upper-case-tag-static-data.patch

* 0005-Shrink-size-of-static-binary-search-tree.patch
|
||||
A PHP specific patch to shrink the size of the static binary search tree for entities.
|
||||
This shrinks the static data size and reduces data cache pressure.
|
||||
* 0006-Patch-out-unused-CSS-style-code.patch
|
||||
A PHP specific patch to remove CSS style and selector bindings from the Lexbor document.
|
||||
|
||||
**Note** for this patch the utilities to generate the tables are also patched.
|
||||
Make sure to apply on a fresh Lexbor clone and run (in `lexbor/utils/encoding`): `python3 single-byte.py` and `python3 multi-byte.py` to generate the tables.
