After this commit there are no more bit rotted files.
The testing program that was in ir.zig has been moved to main.zig
Unsupported command line options have been deleted, or error messages
added.
The compiler repl is available from the build-exe, build-lib,
build-obj commands with the --watch option.
The main zig build script now builds the self-hosted compiler
unconditionally. Linking against LLVM is behind a -Denable-llvm
flag that defaults to off.
* remove deprecated `std.fs.Dir` APIs
* `std.fs.Dir.openDir` now takes a options struct with bool fields for
`access_sub_paths` and `iterate`. It's now much more clear how
opening directories works.
* fixed the std lib and various zig code calling the wrong openDir
function.
* the runtime safety check for dir flags is removed in favor of the
cheaper option of putting a comment on the same line as handling
EBADF / ACCESS_DENIED, since that will show up in stack traces.
closes#4682
The self-hosted compiler is still bit rotted and still not compiling
successfully yet. I have a more serious rework of the code in a
different branch.
* re-introduce `std.build.Target` which is distinct from `std.Target`.
`std.build.Target` wraps `std.Target` so that it can be annotated as
"the native target" or an explicitly specified target.
* `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a
struct which has the tag as well as version range information.
* `std.elf` gains some more ELF header constants.
* `std.Target.parse` gains the ability to parse operating system
version ranges as well as glibc version.
* Added `std.Target.isGnuLibC()`.
* self-hosted dynamic linker detection and glibc version detection.
This also adds the improved logic using `/usr/bin/env` rather than
invoking the system C compiler to find the dynamic linker when zig
is statically linked. Related: #2084
Note: this `/usr/bin/env` code is work-in-progress.
* `-target-glibc` CLI option is removed in favor of the new `-target`
syntax. Example: `-target x86_64-linux-gnu.2.27`
closes#1907
1. behavior tests with --test-evented-io
2. std lib tests with --test-evented-io
3. fuzz test evented I/O a bit, make it robust
4. make sure it works on all platforms (kqueue, Windows IOCP,
epoll/other)
5. restart efforts on self-hosted
* Implements #3768. This is a sweeping breaking change that requires
many (trivial) edits to Zig source code. Array values no longer
coerced to slices; however one may use `&` to obtain a reference to
an array value, which may then be coerced to a slice.
* Adds `IrInstruction::dump`, for debugging purposes. It's useful to
call to inspect the instruction when debugging Zig IR.
* Fixes bugs with result location semantics. See the new behavior test
cases, and compile error test cases.
* Fixes bugs with `@typeInfo` not properly resolving const values.
* Behavior tests are passing but std lib tests are not yet. There
is more work to do before merging this branch.
Thanks to the Windows Process Environment Block, it is possible to
obtain handles to the standard input, output, and error streams without
possibility of failure.
