| | | | | Delete the examples from Crenshaw. They're extremely rudimentary, and they were really just trial runs for the Mu toolchain.

| | | | | I should really stop using /disp8 jumps at the top-level given how inconvenient it is to check for overly large offsets.

* opt: don't clear streams of bytes on the stackKartik K. Agaram2021-04-212-3/+152
| | | | | | | | | | | | All over the Mu code I reflexively initialize all variables just to keep unsafe SubX easy to debug. However I don't really need to do this for safe Mu code, since the type- and memory-safety already ensures we can't read from streams beyond what we've written to them. For now I'll continue mostly with the same approach, but with one exception for streams of bytes. Mu programs often emit traces, and in doing so they often use temporary streams of bytes that can get quite long. I'm hoping avoiding initializing KBs of data all over the place will measurably speed up the Mu shell.

* snapshot: stupid debugging sessionKartik K. Agaram2021-04-052-1/+3
| | | | | | | | | | | | | | | I spent a while building a little keyboard scancode printer: $ ./translate ex1.mu && qemu-system-i386 disk.img ..and wondering why up-arrow was 0x48 in hex but 724 in decimal. I ended up paranoidly poking at a bunch of crap (though there _is_ a cool chromatography-based debugging technique in 126write-int-decimal.subx) before I realized: - 724 just has one extra digit over the correct answer - the 0xe0 scan code is a 3-digit number in decimal -- and the final digit is '4' There's nothing actually wrong.
