2025-11-24runtime: add GODEBUG=tracebacklabels=1 to include pprof labels in tracebacksDavid Finkel
Copy LabelSet to an internal package as label.Set, and include (escaped) labels within goroutine stack dumps. Labels are added to the goroutine header as quoted key:value pairs, so the line may get long if there are a lot of labels. To handle escaping, we add a printescaped function to the runtime and hook it up to the print function in the compiler with a new runtime.quoted type that's a sibling to runtime.hex. (in fact, we leverage some of the machinery from printhex to generate escape sequences). The escaping can be improved for printable runes outside basic ASCII (particularly for languages using non-latin stripts). Additionally, invalid UTF-8 can be improved. So we can experiment with the output format make this opt-in via a a new tracebacklabels GODEBUG var.

2025-11-24cmd/compile: add cases for StringLen to proveDavid Chase
Tricky index-offset logic had been added for slices, but not for strings. This fixes that, and also adds tests for same behavior in string/slice cases, and adds a new test for code in prove that had been added but not explicitly tested. Fixes #76270.

2025-11-23cmd/internal/obj/arm64, image/gif, runtime, sort: use math/bits to calculate ↵Axel Wagner
log2 In several places the integer log2 is calculated using loops or similar mechanisms. math/bits.Len* provide a simpler and more efficient mechanisms for this. Annoyingly, every usage has slightly different ideas of what "log2" means and how non-positive inputs should be handled. I verified the replacements in each case by comparing the result for inputs from 0 to 1<<16.

2025-11-22cmd/go: update default go directive in mod or work initIan Alexander
This commit updates the default go directive when initializing a new module. The current logic is to use the latest version supported by the toolchain. This behavior is simple, predictable, and importantly, it can work while completely offline (i.e., no internet connection required). This commit changes the default version to the following behavior: * If the current toolchain version is a stable version of Go 1.N.M, default to go 1.(N-1).0 * If the current toolchain version is a pre-release version of Go 1.N (Release Candidate M) or a development version of Go 1.N, default to go 1.(N-2).0 This behavior maintains the property of being able to work offline.

Rework these tests such that they are built on all architectures and actually executed when run on riscv64. This increases the likelihood of catching code generation issues, especially those that impact relocations. Also ensure that the generated assembly includes the instruction sequence that is expected for the large branch/call/jump.

2025-11-21cmd/go: support sha1 repos when git default is sha256David Finkel
When git is recent enough (beyond 2.29), always set the --object-format flag. This fixes repo cloning when users have set the git configuration init.defaultObjectFormat to sha256. Git is planning[1] to switch the default hash function to sha256 with the 3.0 release sometime in late 2026. (that may slip, but it's still worth being ahead of the curve) This change moves the version-check function from cl/698835 into codehost/git.go so we can use it to condition setting --object-format=sha1. Adjust the regexp parsing git version output to handle more cases.

2025-11-20spec: adjust rule for type parameter on RHS of alias declarationRobert Griesemer
Per discussion on issue #75885, a type parameter on the RHS of an alias declaration must not be declared in the same declaration (but it may be declared by an enclosing function). This relaxes the spec slightly and allows for (pre-existing) test cases. Add a corresponding check to the type checker (there was no check for type parameters on the RHS of alias declarations at all, before). Fixes #75884. Fixes #75885.

2025-11-20cmd/compile: stack allocate backing stores during appendkhr@golang.org
We can already stack allocate the backing store during append if the resulting backing store doesn't escape. See CL 664299. This CL enables us to often stack allocate the backing store during append *even if* the result escapes. Typically, for code like: func f(n int) []int { var r []int for i := range n { r = append(r, i) } return r } the backing store for r escapes, but only by returning it. Could we operate with r on the stack for most of its lifeime, and only move it to the heap at the return point? The current implementation of append will need to do an allocation each time it calls growslice. This will happen on the 1st, 2nd, 4th, 8th, etc. append calls. The allocations done by all but the last growslice call will then immediately be garbage. We'd like to avoid doing some of those intermediate allocations if possible. We rewrite the above code by introducing a move2heap operation: func f(n int) []int { var r []int for i := range n { r = append(r, i) } r = move2heap(r) return r } Using the move2heap runtime function, which does: move2heap(r): If r is already backed by heap storage, return r. Otherwise, copy r to the heap and return the copy. Now we can treat the backing store of r allocated at the append site as not escaping. Previous stack allocation optimizations now apply, which can use a fixed-size stack-allocated backing store for r when appending. See the description in cmd/compile/internal/slice/slice.go for how we ensure that this optimization is safe.
