* sys: support type aliases (aka typedefs)Dmitry Vyukov2018-01-081-0/+14
| | | | | | | | | | | | | | | | | | | | | | Complex types that are often repeated can be given short type aliases using the following syntax: ``` type identifier underlying_type ``` For example: ``` type signalno int32[0:65] type net_port proc[20000, 4, int16be] ``` Then, type alias can be used instead of the underlying type in any contexts. Underlying type needs to be described as if it's a struct field, that is, with the base type if it's required. However, type alias can be used as syscall arguments as well. Underlying types are currently restricted to integer types, `ptr`, `ptr64`, `const`, `flags` and `proc` types.

* pkg/compiler: check and generate typesDmitry Vyukov2017-09-021-2/+2
| | | | | | Move most of the logic from sysgen to pkg/compiler. Update #217

* pkg/compiler, sys/syz-sysgen: move const handling to pkg/compilerDmitry Vyukov2017-08-271-17/+25
| | | | Now pkg/compiler deals with consts.
* sys/syz-sysgen: switch to new parserDmitry Vyukov2017-08-181-0/+31
| | | | | For now we just generate the old structs from the new AST. But this allows to delete the old parser entirely.

* pkg/ast: new parser for sys descriptionsDmitry Vyukov2017-08-181-0/+423
The old parser in sys/sysparser is too hacky, difficult to extend and drops debug info too early, so that we can't produce proper error messages. Add a new parser that is build like a proper language parser and preserves full debug info for every token.
