Alex Rønne Petersen
3d6f83b331 std.Target: Adjust DynamicLinker.standard() for NetBSD. 
* powerpc64 does not appear to be a thing.
* riscv32/riscv64 have not had actual releases yet.

9af8e7c68e std.c: Fill out some missing definitions for supported NetBSD libc targets. 
This allows ubsan-rt to build.

d47cc5777d test: Remove some nonsensical NetBSD targets from llvm_targets. 
* mips64/mips64el on NetBSD are soft float; we have no support for this yet.
* powerpc64 does not appear to be a thing.
* riscv32/riscv64 have not seen official releases yet.

0d35a7760e freebsd: Fix selection of unversioned symbol inclusion. 
We want the latest unversioned inclusion that fits the target version. This
theoretically matters because it might have a different global vs weak linkage
compared to an older inclusion.

e52ffe6738 glibc: Fix a benign bug when selecting the size of an object symbol. 
This didn't cause any problems in practice, but doing it this way is technically
more correct.

56fad6a195 make error messages prettier 
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.

518105471e Fix SIGSEGV handler for AArch64 Darwin targets 
* 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

9d8adb38a1 std.Build: Make no_builtin a property of Module instead of Step.Compile. 
This reflects how the compiler actually treats it.

Closes #23424.

44bf64a709 llvm: Fix a bunch of volatile semantics violations.

427810f3ed llvm: Don't set nonnull attribute on pointers in non-generic address spaces. 
LLVM considers null pointers to be valid for such address spaces.

e95e7651ec llvm: Set null_pointer_is_valid attribute when accessing allowzero pointers. 
This informs optimization passes that they shouldn't assume that a load from a
null pointer invokes undefined behavior.

Closes #15816.

5c2e300f42 Air: Fix mustLower() to consider volatile for a handful of instructions. 
These can all potentially operate on volatile pointers.
 2025-05-12 17:07:49 +02:00

47aaaec6ea Air: Always return true for inline assembly in mustLower(). 
AstGen requires inline assembly to either have outputs or be marked volatile, so
there doesn't appear to be any point in doing these checks.

f3e851dbd0 compiler: Link libc by default when targeting FreeBSD. 
We don't yet have a direct syscall layer in std.os.freebsd.

4c2f1e01a7 freebsd: Create strong references to __progname and environ in stub libc.so. 
These symbols are defined in the statically-linked startup code. The real
libc.so.7 contains strong references to them, so they need to be put into the
dynamic symbol table.

2116f2e3b2 Compilation: Don't pass -mabi to Clang on powerpc64(le)-freebsd. 
The driver doesn't support it, and FreeBSD 13+ on PPC64 uses ELFv2 anyway.
 2025-05-10 20:58:28 +02:00

d3a6236eef compiler: Support building FreeBSD crt1.o/Scrt1.o and stub shared libraries. 
Only works for FreeBSD 14+. Note that we still default to targeting FreeBSD 13.

Contributes to #2876.

837e0f9c37 std.Target: Remove ObjectFormat.nvptx (and associated linker code). 
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.
