| 2024-08-13 | elf: allocate new offset table via Atom.allocate mechanism | Jakub Konka | |

| 2024-08-12 | all: Handle spirv in addition to spirv(32,64) where applicable. | Alex Rønne Petersen | |
| Some of this is arbitrary since spirv (as opposed to spirv32/spirv64) refers to the version with logical memory layout, i.e. no 'real' pointers. This change at least matches what clang does. | |||
| 2024-08-12 | std.Target: Rename glsl450 Arch tag to opengl. | Alex Rønne Petersen | |
| Versions can simply use the normal version range mechanism, or alternatively an Abi tag if that makes more sense. For now, we only care about 4.5 anyway. | |||
| 2024-08-11 | compiler: split Decl into Nav and Cau | mlugg | |
| The type `Zcu.Decl` in the compiler is problematic: over time it has gained many responsibilities. Every source declaration, container type, generic instantiation, and `@extern` has a `Decl`. The functions of these `Decl`s are in some cases entirely disjoint. After careful analysis, I determined that the two main responsibilities of `Decl` are as follows: * A `Decl` acts as the "subject" of semantic analysis at comptime. A single unit of analysis is either a runtime function body, or a `Decl`. It registers incremental dependencies, tracks analysis errors, etc. * A `Decl` acts as a "global variable": a pointer to it is consistent, and it may be lowered to a specific symbol by the codegen backend. This commit eliminates `Decl` and introduces new types to model these responsibilities: `Cau` (Comptime Analysis Unit) and `Nav` (Named Addressable Value). Every source declaration, and every container type requiring resolution (so *not* including `opaque`), has a `Cau`. For a source declaration, this `Cau` performs the resolution of its value. (When #131 is implemented, it is unsolved whether type and value resolution will share a `Cau` or have two distinct `Cau`s.) For a type, this `Cau` is the context in which type resolution occurs. Every non-`comptime` source declaration, every generic instantiation, and every distinct `extern` has a `Nav`. These are sent to codegen/link: the backends by definition do not care about `Cau`s. This commit has some minor technically-breaking changes surrounding `usingnamespace`. I don't think they'll impact anyone, since the changes are fixes around semantics which were previously inconsistent (the behavior changed depending on hashmap iteration order!). Aside from that, this changeset has no significant user-facing changes. Instead, it is an internal refactor which makes it easier to correctly model the responsibilities of different objects, particularly regarding incremental compilation. The performance impact should be negligible, but I will take measurements before merging this work into `master`.

| 2024-08-10 | Wasm: handle ref to an extern in getDeclVAddr | Jakub Konka | |
| 2024-08-10 | Coff: handle ref to an extern in getDeclVAddr | Jakub Konka | |
| 2024-08-10 | MachO/ZigObject: handle ref to an extern in getDeclVAddr | Jakub Konka | |
| 2024-08-10 | Elf/ZigObject: handle ref to an extern in getDeclVAddr | Jakub Konka | |
| Prior to this change, we would unconditionally create a symbol and atom pair for a Decl that could point to an extern, in which case no atom can be created. | |||
