2025-01-21Sema: fix `is_non_null_ptr` handling for runtime-known pointersmlugg
We can still often determine a comptime result based on the type, even if the pointer is runtime-known. Also, we previously used load -> is non null instead of AIR `is_non_null_ptr` if the pointer is comptime-known, but that's a bad heuristic. Instead, we should check for the pointer to be comptime-known, *and* for the load to be comptime-known, and only in that case should we call `Sema.analyzeIsNonNull`. Resolves: #22556

2025-01-19llvm: convert `@divFloor` and `@mod` to forms llvm will recognizeJacob Young
On x86_64, the `@divFloor` change is a strict improvement, and the `@mod` change adds one zero latency instruction. In return, once we upgrade to LLVM 20, when the optimizer discovers one of these operations has a power-of-two constant rhs, it will be able to optimize the entire operation into an `ashr` or `and`, respectively. #I CPL CPT old `@divFloor` | 8 | 15 | .143 | new `@divFloor` | 7 | 15 | .148 | old `@mod` | 9 | 17 | .134 | (rip llvm new `@mod` | 10 | 17 | .138 | scheduler)

2025-01-18x86_64: enable struct field reorderingJacob Young
The blocker for enabling this feature was my need to debug the emitted assembly without debug info and having to manually inspect memory to determine struct contents. However, we now have debug info! (lldb) v -L foo bar 0x00007fffffffda20: (repro.repro.Foo) foo = { 0x00007fffffffda24: .x = 12 0x00007fffffffda20: .y = 34 } 0x00007fffffffda28: (repro.repro.Bar) bar = { 0x00007fffffffda28: .x = 56 0x00007fffffffda2c: .y = 78 } Updates #21530

Documentation for this will be on the wiki shortly. Resolves: #21842
2025-01-16all: update to `std.builtin.Type.Pointer.Size` field renamesmlugg
This was done by regex substitution with `sed`. I then manually went over the entire diff and fixed any incorrect changes. This diff also changes a lot of `callconv(.C)` to `callconv(.c)`, since my regex happened to also trigger here. I opted to leave these changes in, since they *are* a correct migration, even if they're not the one I was trying to do!
