New CLI parameter: --c-source [options] [file]
It even works with `--cache on` when there are transitive dependencies.
Instead of `builder.addCExecutable`, use `builder.addExecutable` and pass
`null` for the root source file. Then use `builder.addCSourceFile`,
which takes the path to the C code, and a list of C compiler args.
Be sure to linkSystemLibrary("c") if you want libc headers to be
available.
Merge TestStep into LibExeObjStep. That was long overdue.
* When you do field access of a type which only has one possible
value, the result is comptime-known.
* StorePtr instructions which operate on pointers to types which
only have one possible value, the result is a comptime no-op.
closes#1554
* Separate LoadPtr IR instructions into pass1 and pass2 variants.
* Define `type_size_bits` for extern structs to be the same as
their `@sizeOf(T) * 8` and allow them in packed structs.
* More helpful error messages when trying to use types in
packed structs that are not allowed.
* Support arrays in packed structs even when they are not
byte-aligned.
* Add compile error for using arrays in packed structs when the
padding bits would be problematic. This is necessary since
we do not have packed arrays.
closes#677
* `type_size_store` is no longer a thing. loading and storing a pointer
to a value may dereference up to `@sizeOf(T)` bytes, even for
integers such as `u24`.
* fix `types_have_same_zig_comptime_repr` to not think that the
same `ZigTypeId` means the `ConstExprValue` neccesarily has the
same representation.
* implement `buf_write_value_bytes` and `buf_read_value_bytes` for
`ContainerLayoutPacked`
closes#1120
* also fix extern variables with initialiaztion values to generate runtime code
* remove the workaround in example/shared_library/mathtest.zig
* introduce the ability for global variables to have Weak and LinkOnce
linkage
* fix `@export` to work for non-functions. this code needs to be
audited though.
* fix comptime ptrcast not keeping bigger alignment
* fix linker warnings when targeting darwin

Previously, if a dereference instruction was an lvalue, it would fail to
typecheck that the value being dereferenced was indeed a pointer.
Although a little clunky, this change obviates the need for redundant
type checks scattered about the analysis.
this adds the prototype of panic to @import("builtin")
and then uses it to do an implicit cast of the panic
function to this prototype, rather than redoing all the
implicit cast logic.

* Fixes breaches of the guarantee that `@sizeOf(T) >= @alignOf(T)`
* Fixes std.mem.secureZero for integers where this guarantee previously
was breached
* Fixes std.mem.Allocator for integers where this guarantee previously
was breached

It's still best practice to put `@setEvalBranchQuota` at the top of
the comptime stack, but as Jimmi notes in #1949, when a function
can be called at comptime and also can be the top of the comptime stack,
this compile error is fundamentally unsound.
So now it's gone.
