This removes the remaining hack in the implementation of anonymous
struct literals, and they can now therefore now have greater than 16
fields/elements.
This commit also hooks up type coercion (previously called implicit
casting) into the result location mechanism, and additionally hooks up
variable declarations, maintaining the property that:
var a: T = b;
is semantically equivalent to:
var a = @as(T, b);
See #1757
d91fc0fdd8 changed zig's behavior to
disable the SSE feature when cross compiling for i386-freestanding.
This commit does the same when compiling C Code.
Clang does not support -march=native for all targets.
Arguably it should always work, but in reality it gives:
error: the clang compiler does not support '-march=native'
If we move CPU detection logic into Zig itelf, we will not need this,
instead we will always pass target features and CPU configuration explicitly.
For now, we simply avoid passing the flag when it is known to not be
supported.
* All the data types from `@import("builtin")` are moved to
`@import("std").builtin`. The target-related types are moved
to `std.Target`. This allows the data types to have methods, such as
`std.Target.current.isDarwin()`.
* `std.os.windows.subsystem` is moved to
`std.Target.current.subsystem`.
* Remove the concept of the panic package from the compiler
implementation. Instead, `std.builtin.panic` is always the panic
function. It checks for `@hasDecl(@import("root"), "panic")`,
or else provides a default implementation.
This is an important step for multibuilds (#3028). Without this change,
the types inside the builtin namespace look like different types, when
trying to merge builds with different target settings. With this change,
Zig can figure out that, e.g., `std.builtin.Os` (the enum type) from one
compilation and `std.builtin.Os` from another compilation are the same
type, even if the target OS value differs.
* use erase rest of line escape code.
* use `stderr.supportsAnsiEscapeCodes` rather than `isTty`.
* respect `--color off`
* avoid unnecessary recursion
* add `Progress.log`
* disable the progress std lib test since it's noisy and uses
`time.sleep()`.
* enable/integrate progress printing with the default test runner
This commit adds `-fgenerate-docs` CLI option, and it outputs:
* doc/index.html
* doc/data.js
* doc/main.js
In this strategy, we have 1 static html page and 1 static javascript
file, which loads the semantic analysis dump directly and renders it
using dom manipulation.
Currently, all it does is list the declarations. But there is a lot more
data available to work with. The next step would be making the
declarations hyperlinks, and handling page navigation.
Another strategy would be to generate a static site with no javascript,
based on the semantic analysis dump that zig now provides. I invite the
Zig community to take on such a project. However this version which
heavily relies on javascript will also be a direction explored.
I also welcome contributors to improve the html, css, and javascript of
what this commit started, as well as whatever improvements are necessary
to the static analysis dumping code to provide more information.
See #21.
This commit adds -fdump-analysis which creates
a `$NAME-analysis.json` file with all of the finished
semantic analysis that the stage1 compiler produced.
It contains types, packages, declarations, and files.
This is an initial implementation; some data will be
missing. However it's easy to improve the implementation,
which is in `src/dump_analysis.cpp`.
The next step for #21 will be to create Zig code which parses
this json file and creates user-facing HTML documentation.
This feature has other uses, however; for example, it could
be used for IDE integration features until the self-hosted
compiler is available.
Until ability to specify target CPU features (#2883) is done, this
commit gives riscv target better default features.
This side-steps #3275 which is a deficiency in compiler-rt when features
do not include 32 bit integer division.
With this commit, RISC-V compiler-rt tests pass and Hello World works
both pure-zig and with musl libc.
