2020-06-24self-hosted: add compare output test for new AST->ZIR codeAndrew Kelley
2020-06-24self-hosted: fix test regressionsAndrew Kelley
I'm allowing incremental compilation of ZIR modules to be broken. This is not a real use case of ZIR, and the feature requires a lot of code duplication with incremental compilation of Zig AST (which works great).

2020-05-27self-hosted: introduce a virtual address allocation schemeAndrew Kelley
The binary file abstraction changed its struct named "Decl" to "TextBlock" and it now represents an allocated slice of memory in the .text section. It has two new fields: prev and next, making it a linked list node. This allows a TextBlock to find its neighbors. The ElfFile struct now has free_list and last_text_block fields. Doc comments for free_list are reproduced here: A list of text blocks that have surplus capacity. This list can have false positives, as functions grow and shrink over time, only sometimes being added or removed from the freelist. A text block has surplus capacity when its overcapacity value is greater than minimum_text_block_size * alloc_num / alloc_den. That is, when it has so much extra capacity, that we could fit a small new symbol in it, itself with ideal_capacity or more. Ideal capacity is defined by size * alloc_num / alloc_den. Overcapacity is measured by actual_capacity - ideal_capacity. Note that overcapacity can be negative. A simple way to have negative overcapacity is to allocate a fresh text block, which will have ideal capacity, and then grow it by 1 byte. It will then have -1 overcapacity. The last_text_block keeps track of the end of the .text section. Allocation, freeing, and resizing decls are all now more sophisticated, and participate in the virtual address allocation scheme. There is no longer the possibility for virtual address collisions.

2019-11-21string literals are now null terminatedAndrew Kelley
this also deletes C string literals from the language, and then makes the std lib changes and compiler changes necessary to get the behavior tests and std lib tests passing again.

2018-07-24fix race conditions in self-hosted compiler; add testAndrew Kelley
* fix race condition in std.event.Channel deinit * add support to zig build for --no-rosegment * add passing self-hosted compare-output test for calling a function * put a global lock on LLD linking because it's not thread safe
2018-07-23self-hosted: add first compare-output testAndrew Kelley
2018-07-20self-hosted: implicit cast comptime ints to other intsAndrew Kelley
we now have successful exit codes from main linking against libc

* outside fn definition * inside defer expression
2018-07-11add std.event.FutureAndrew Kelley
This is like a promise, but it's for multiple getters, and uses an event loop.
