4eff0f4ea1 macho: fix condition for checking available size for an atom 2021-09-01 16:49:16 +02:00

7a99cd069a macho: clean up allocating atom logic 
Instead of checking for stage1 at every callsite, move the logic
inside `allocateAtom`. This is fine since this logic will disappear
anyhow once I add expanding and shifting segments and sections.

4f0aa7d639 std: Use truncating cast in WIFSTOPPED for Linux, FreeBSD and DragonFly 
The intermediate value can be larger than an u16, so @truncate is needed
to match the behavior of musl.

2831d6e9b8 macho: add first pass at allocating parsed atoms in objects 
This commit makes it possible to combine self-hosted with a pre-compiled
C object file, e.g.:

```
zig-out/bin/zig build-exe hello.zig add.o
```

where `add.o` is a pre-compiled C object file.

4bb5d17edc AstGen: pre-scan all decls in a namespace 
Also:
 * improve the "ambiguous reference" error by swapping the order of
   "declared here" and "also declared here" notes.
 * improve the "not accessible from inner function" error:
   - point out that it has to do with the thing being mutable
   - eliminate the incorrect association with it being a function
   - note where it crosses a namespace boundary
 * struct field types are evaluated in a context that has the struct
   namespace visible. Likewise with align expressions, linksection
   expressions, enum tag values, and union/enum tag argument
   expressions.

05cf44933d stage2: delete keywords true, false, undefined, null 
The grammar does not need these as keywords; they are merely primitives
provided by the language the same as `void`, `u32`, etc.

6a6e2cd64f AstGen: allow locals with same name as primitives with @"" syntax

f30aa25cbf declarations may collide with primitives with @"" syntax 
* stage2 AstGen: add missing compile error for declaring a local
   that shadows a primitive. Even with `@""` syntax, it may not have
   the same name as a primitive.
 * stage2 AstGen: add a compile error for a global declaration
   whose name matches a primitive. However it is allowed when using
   `@""` syntax.
 * stage1: delete all "declaration shadows primitive" compile errors
   because they are now handled by stage2 AstGen.
 * stage1/stage2 AstGen: notice when using `@""` syntax and:
   - treat `_` as a regular identifier
   - skip checking if an identifire is a primitive

Check the new test cases for clarifications on semantics.

cfae70ec8e Make slice always return a reference 
Previously this returned an rvalue, which leads to unexpected behaviour
when writing expressions such as `x[1..][1..].`

3aa533519d Store to mutable pointer in analyzeRef

3a3704be05 Don't use .none_or_ref for for(expr) 
We can already know whether the user want the expression to be a pointer or
ref based on whether the asterisk token is used, like with if and switch.

ad4a8e7665 macho: keep actual file offset for zerofill sections separately 
This way, we will conform to the standard practice of setting the
offset within the section header to the beginning of the file and
we will be able to track the location of the section in the file
for incremental updates.
