This prevents symbols from these libraries from polluting the dynamic symbol
tables of binaries built with Zig. The downside is that we no longer deduplicate
the symbols at run time due to weak linkage.
Closes#7935.
Closes#13303.
Closes#19342.
This function was broken, because it took ownership of the buffer on
error *sometimes*, in a way which the caller could not tell. Rather than
trying to be clever, it's easier to just follow the same interface as
all other `addFilePost` methods, and not take ownership of the path.
This is a breaking change. The next commits will apply it to the
compiler, which is the only user of this function in the ziglang/zig
repository.
This code applies to ~any POSIX OS where we don't link libc. For example, it'll
be useful for FreeBSD and NetBSD.
As part of this, move std.os.linux.pie to std.pie since there's really nothing
Linux-specific about what that file is doing.
* sysident_assym.h was manually expanded.
* The ELF_NOTE_MARCH_DESC and ELF_NOTE_MARCH_DESCSZ macros will be defined
by the compiler.
* Legacy .init/.fini stuff was removed.
* GCJ nonsense was removed.
It's incorrect to ever set `include_reference_trace` here, because the
compiler has already given or not given reference traces depending on
the `-freference-trace` option propagated to the compiler process by
`std.Build.Step.Compile`.
Perhaps in future we could make the compiler always return the reference
trace when communicating over the compiler protocol; that'd be more
versatile than the current behavior, because the build runner could, for
instance, show a reference trace on-demand without having to even invoke
the compiler. That seems really useful, since the reference trace is
*often* unnecessary noise, but *sometimes* essential. However, we don't
live in that world right now, so passing the option here doesn't make
sense.
Resolves: #23415
Error messages never contain periods or grave accents.
Get rid of the periods and use apostrophes instead in
probably the only two error messages that had them.
* ucontext_t ptr is 8-byte aligned instead of 16-byte aligned which @alignCast() expects
* Retrieve pc address from ucontext_t since unwind_state is null
* Work around __mcontext_data being written incorrectly by the kernel
Textual PTX is just assembly language like any other. And if we do ever add
support for emitting PTX object files after reverse engineering the bytecode
format, we'd be emitting ELF files like the CUDA toolchain. So there's really no
need for a special ObjectFormat tag here, nor linker code that treats it as a
distinct format.
* NT_FREEBSD_ABI_TAG was manually adjusted from using a hardcoded value to using
__FreeBSD_version which will be defined by the compiler.
* GCJ stuff was removed.
* HAVE_CTORS definitions were removed.
* Introduce common `bzero` libc implementation.
* Update test name according to review

* address code review
- import common implementation when musl or wasi is included
- don't use `c_builtins`, use `@memset`
* bzero calling conv to .c
* Apply review
