Sadly due to a workaround for LLD linker limitations on macOS
we cannot put libuserland into an .a file; instead we have to use object
files. Again due to linker limitations, bundling compiler_rt.o into
another relocatable object also doesn't work. So we're left with
disabling stack probing on macOS for the stage1 self-hosted code.
These workarounds could all be removed if the macos support in the LLD
linker improved, or if Zig project had its own linker that did not have
these issues.
and use it when building libuserland.a
The self-hosted part of stage1 relies on zig's compiler-rt, and so we
include it in libuserland.a.
This should potentially be the default, but for now it's behind a linker
option.
self-hosted translate-c: small progress on translating functions.
Previously if you had, for example:
extern "c" threadlocal var errno: c_int;
This would turn errno into a normal variable for --single-threaded
builds. However for variables with external linkage, there is an ABI
to uphold.
This is needed to make errno work for DragonFly BSD. See #2381.
When using `@memset` to set bytes to `undefined`, Zig notices this
case and does a single Valgrind client request rather than N.
Speeds up all allocators in safe modes.
Closes#2388
Avoid producing Zig code that doesn't compile due to mismatched
alignments between pointers.
Always emit a @alignOf instead of hardcoding the alignment value
returned by LLVM for portability sake of the generated code.
zig --help -> ok
zig --help --c-source -> ok
zig --c-source --help -> crash [fixed]
'i' was being incremented without regard for the 'argc' limit, so
we were running off the end of 'argv'.
The code creates temporary ConstExprValue with global_refs set to
nullptr and that's carried over to the final value. Doing so prevents
the deduplication mechanism to work correctly, causing all sorts of
runtime crashes.
Fixes#1636Fixes#1608 (Even though it was already fixed by #1991)
Previously, `zig fmt` on the stage1 compiler (which is what we currently
ship) would perform what equates to `zig run std/special/fmt_runner.zig`
Now, `zig fmt` is implemented with the hybrid zig/C++ strategy outlined
by #1964.
This means Zig no longer has to ship some of the stage2 .zig files, and
there is no longer a delay when running `zig fmt` for the first time.
After 4df2f3d74f test names have the word "test" in them so the
redundant word is removed from test runner. Also move the prefix/suffix
to where it logically belongs in the fully qualified symbol name.
Tests now have the symbol name of the format `test "<name>"` in order
to be more easily distinguished from functions with similar names.
See issue #2267.
This defines `@sizeOf` to be the runtime size of a type, which means
that it is zero for types such as comptime_int, type, and (enum
literal).
See #2209
const_ptr_pointee_unchecked did not take into account that if the
pointer is zero sized, then const_val->data.x_ptr.special would be
ConstPtrSpecialInvalid. This commit fixes this by also checking
that the child type of the pointer only have one possible value
and just returns that value.
