| | | | | | Bit-shifts aren't quite right yet. We need to emit /imm8 rather than /imm32. This commit introduces the field, though we don't use it yet.
* 6648 - bit-shift instructions in MuKartik Agaram2020-07-142-0/+138
| | | | I'm not happy with the names.
* 6647Kartik Agaram2020-07-141-4/+4
|
* 6645 - heap allocations in MuKartik Agaram2020-07-132-2/+303
| | | | | | | | - allocate var - populate var, n Both rely on the type of `var` to compute the size of the allocation. No need to repeat the name of the type like in C, C++ or Java.

* 6638 - require '0x' prefix on multi-digit literalsKartik Agaram2020-07-112-1/+135
| | | | | | Mu exclusively uses hex everywhere for a consistent programming experience from machine code up. But we all still tend to say '10' when we mean 'ten'. Catch that early.
* 6637Kartik Agaram2020-07-112-0/+9
| | | | Be more consistent about what we interpret as integer literals.

* 6622 - new syscalls: time and ntimeKartik Agaram2020-07-0826-0/+0
| | | | | As a side-effect I find that my Linode can print ~100k chars/s. At 50 rows and 200 columns per screen, it's 10 frames/s.

| | | | | | This commit reimplements commit 6515 to happen during type-checking rather than as early as possible. That way we naturally get a more informative error message.
