| | | | | | Draft 3. Getting close. Now the tree structure seems right.

| | | | Draft 2.
* 5905Kartik Agaram2020-01-201-84/+329
| | | | | | | Draft of my first, incorrect attempt at parsing s-expressions. No matter how many times I've done this, I never get it right the first time.

* 5898 - strengthen slice-empty? checkKartik Agaram2020-01-1915-7/+36
| | | | | | | | | | | Anytime we create a slice, the first check tends to be whether it's empty. If we handle ill-formed slices here where start > end, that provides a measure of safety. In the Mu translator (mu.subx) we often check for a trailing ':' or ',' and decrement slice->end to ignore it. But that could conceivably yield ill-formed slices if the slice started out empty. Now we make sure we never operate on such ill-formed slices.
* 5897 - rename comparison instructionsKartik Agaram2020-01-16114-1140/+1124
| | | | | | | Signed and unsigned don't quite capture the essence of what the different combinations of x86 flags are doing for SubX. The crucial distinction is that one set of comparison operators is for integers and the second is for addresses.

* 5887 - reorganize libraryKartik Agaram2020-01-1421-9/+16
| | | | | | | Layers 0-89 are used in self-hosting SubX. Layers 90-99 are not needed for self-hosting SubX, and therefore could use transitional levels of syntax sugar. Layers 100 and up use all SubX syntax sugar.

* 5883 - drop the `ref` keywordKartik Agaram2020-01-1241-384/+365
| | | | | | | | | | When I created it I was conflating two things: a) needing to refer to just the start, rather than the whole, and b) counting indirections. Both are kinda ill-posed. Now Mu will have just `addr` and `handle` types. Normal types will translate implicitly to `addr` types, while `handle` will always require explicit handling.

| | | | | | | | Stop requiring '--debug' in 'bootstrap run'. Now it's smart enough to turn on when needed. This creates some small chance of reading stale debug info for the wrong binary, but in practice that hasn't been an issue.

| | | | | | | | | Just clarified for myself why `subx translate` and `subx run` need to share code: emulation supports the tests first and foremost. In the process we clean up our architecture for levels of layers. It's a good idea but unused once we reconceive of "level 1" as just part of the test harness.
* 5862Kartik Agaram2020-01-012-164/+172
| | | | | Deemphasize details of x86 addressing modes. I want people using SubX's syntax sugar now.

* 5858Kartik Agaram2020-01-0197-10/+8
| | | | | | Move script to create a Soso boot image into a sub-directory. I'm trying to streamline newcomer attention to just a couple of use cases.
