2022-12-18llvm: avoid creating an invalid llvm typeJacob Young
Fixes the following assertion: ``` zig: llvm/lib/IR/Type.cpp:729: static llvm::PointerType* llvm::PointerType::get(llvm::Type*, unsigned int): Assertion `isValidElementType(EltTy) && "Invalid type for pointer element!"' failed. ```
2022-12-18llvm: fix lowering pointer to final zero-width field of a comptime valueJacob Young
* Handle a `null` return from `llvmFieldIndex`. * Add a behavior test to test this code path. * Reword this test name, which incorrectly described how pointers to zero-bit fields behave, and instead describe the actual test.

value" This reverts commit e0bc5f65b98d154b4318027d56f780b55605e33c. Caused an assertion failure when running the behavior tests: ``` zig: llvm/lib/IR/Type.cpp:729: static llvm::PointerType* llvm::PointerType::get(llvm::Type*, unsigned int): Assertion `isValidElementType(EltTy) && "Invalid type for pointer element!"' failed. Aborted (core dumped) ```

2022-12-10CBE: fix compiling for aarch64-windowsJacob Young
These bugs were triggered in the C backend by aarch64-specific code in os/windows.zig. Intentionally not updating zig1.wasm yet because of upcoming changes and since aarch64-windows is not tested on master yet.

2022-12-09llvm: resolve all relative paths when creating DIFilesJakub Konka
This will make stack traces and debugging experience more consistent in the sense that the presence of source lines in stack traces will not be dependent on the current working directory of the running process.
2022-12-06remove most conditional compilation based on stage1Andrew Kelley
There are still a few occurrences of "stage1" in the standard library and self-hosted compiler source, however, these instances need a bit more careful inspection to ensure no breakage.

2022-12-04CBE: defer invariant local reuse in loopsJacob Young
When a local defined outside a loop dies inside the loop, it can still be needed on subsequent loop iterations, so reuse of the local must be deferred until after the loop ends. This causes behavior tests to pass.

2022-12-04CBE and LLVM: handle unused try instructionsAndrew Kelley
In both backends they did not observe the Liveness information for try instructions. Now they do. For the C backend this is necessary for correctness; for the LLVM backend, it improves code generation.

2022-12-02cbe: add support for constraint modifiers specified after a colonJacob Young
This translates `%[name:mod]` to `%mod[name]` for C.

2022-12-02CBE: use bool, true, false, instead of `zig_` prefixesAndrew Kelley
In general the C backend should lower to human-maintainable C code whenever possible. Directly using C types that one would use when writing C code is one part of the strategy. The concern with including stdint.h is C89 compatibility. Well, we can just check the C std lib version before deciding to include that header.
2022-12-02CBE: use a 0 literal instead of `error.@"(no error)"`Andrew Kelley
This saves bytes and is easier to read too.
