| | | | | This seems like the final helper we need for Phase 2. Now to build the business logic itself.
* 4947Kartik Agaram2019-02-012-0/+2
| | | | | | | | Bugfix: has-metadata? was corrupting registers Seems uneconomic to write tests for stuff like this. Assembly is just not the right layer to try to come up with a general solution or process. Keep running your code and wait to find signs of breakage.

| | | | | In the process of building slice primitives I found an out-of-bounds access in write-byte.
* 4915Kartik Agaram2019-01-084-11/+213
| | | | | | In the process of building next-token I finally added some support for a debugging situation I've found myself in a couple of times: wondering "what changed this memory location"?

| | | | Improve error checking to warn on unexpected displacements as well.
* 4908Kartik Agaram2019-01-058-4/+41
| | | | | | | | Fix CI. a) Update canonical binaries. b) Fix an out-of-bounds access in `clear-stream`. This also required supporting a new instruction in `subx run` to load an imm8 into rm8.

* 4906 - helper to allocate streams on the heapKartik Agaram2019-01-042-0/+175
|
* 4905 - safe ptr lookup is now 6 instructionsKartik Agaram2019-01-042-25/+20
| | | | | | | | | | | | | The lines within '{}' can now be turned into a macro like `E_X = deref(E_X)`, parameterizing the register being modified. Assumes the input is in a register but also saved elsewhere, so it's safe to clobber and replace with the result. Compare commit 4894. Used to take 9 instructions, 8 of them making loads/stores. Now it's 6 instructions, 4 of them loads/stores (the one non-local load is unchanged, of course). Key is to not consume more registers so we don't have to push/pop them.

| | | | I've agonized over this for a week; high time I saved a snapshot.

| | | | | | | | | | | Finally really fix the CI failure of commit 4894. This is a remainder to forget my knowledge of stack addresses in the SubX VM when writing SubX programs. Otherwise my programs will work in the VM but not natively. The only assumptions a SubX program should make about its segment addresses are what's encoded in the ELF binary. Thanks to https://en.wikipedia.org/wiki/Address_space_layout_randomization, it can't know anything else.
