yeah, eabi is a lot better, as is the abi we use for the watch

the watch has its own abi ?

(as a related matter: does the touchbar run the same OS as the watch?)

what do you mean when you say "the same OS"?

well it didn't dawn on me until you guys brought it up that they would be anything but ios

since you are using a non-ios 32 bit abi, does that mean the whole system is 32 bit? is there a 32 bit kernel shared between watchos and ... whatever runs on the touchbar embedded thing?

c/++ are supposed to compile down to asm in a very direct manner. if you want higher level functionality, you need to look elsewhere

that’s the kind of thinking that gets you systems so bloated they can’t even run on a calculator

a modern hand calculator has an arm chip and gobs of ram

you could run java just fine if you wanted to

I would like to write a toy compiler (or even just an interpreter for a toy language) but not want to have to read 10,000 pages first. Where should I realistically start?

for specifically compilers i am fond of the lcc book
