Maria Matejka f74d19765e Filter: Getting rid of RESULT_OK. Adding RESULT_VOID.
This is a preparation for filter pre-evaluation.

Maria Matejka 63f49457dc Filter: renaming pointers for consistency
The struct f_inst * is now always "what"
and the union member pointer is always "whati".

Maria Matejka bd91338246 Filter: Dropped the setter instructions in favor of direct result storage.
This should help filter performance a bit.

Maria Matejka 1757a6fce5 Filter: Stacks moved to thread-local storage if available. 2019-05-29 21:03:52 +02:00
Jan Maria Matejka 23e3b1e665 Filter: Some people can't pronounce "postfixify" correctly. Let's try "linearize" instead.
This is just a naming change.

Maria Matejka 4c553c5a5b Filter refactoring: dropped the recursion from the interpreter
This is a major change of how the filters are interpreted. If everything
works how it should, it should not affect you unless you are hacking the
filters themselves.

Anyway, this change should make a huge improvement in the filter performance
as previous benchmarks showed that our major problem lies in the
recursion itself.

There are also some changes in nest and protocols, related mostly to
spreading const declarations throughout the whole BIRD and also to
refactored dynamic attribute definitions. The need of these came up
during the whole work and it is too difficult to split out these
not-so-related changes.

Maria Matejka 8436040735 Filter refactoring: Drop the roa check specific f_inst 2019-02-20 22:30:54 +01:00
Maria Matejka ca2ee91a80 Filter refactoring: The constant f_val is simply included inside the instruction
With 32 bits, size of the args is 12 bytes, the f_val is 20 bytes.
With 64 bits, size of the args is 24 bytes, the f_val the same.

This is not so nice on 32 bits, anyway the f_inst itself is
24 vs. 32 bytes and the overall size of filters must be 32k of
instructions to get to one megabyte of RAM eaten by f_inst.

Therefore it seems to be improbable for common user to get into
problems with this change.

Jan Maria Matejka 7afa143886 Filter refactoring: Passing the resulting struct f_val as a pointer.
This also drops the multiplexing of errors with the f_val itself
together with the T_RETURN f_val type flag.
