2026-02-12cmd/compile: set alignment for all content-addressable symbolsIan Lance Taylor
There is nothing particularly special about content-addressable symbols, it's just a place to start. This reduces the size of the tailscaled binary by about 16K. This happens mainly because before this CL the linker's symalign function kicks in for all static composite literals and PCDATA symbols, and gives them an alignment based on their size. If the size happens to be a multiple of 32, it gets an alignment of 32. That wastes space.

2026-02-10cmd/internal/obj: add Align field to LSymIan Lance Taylor
This will permit the compiler and assembler to specify the alignment of symbols that they create. Careful placement of the new field, plus rearranging an existing field, means that LSym does not change size (as tested by TestSizeof). The new alignment field is int16, permitting alignment up to 16384, more than we ever need in practice. If necessary we could change the field to uint8 and store the alignment as a power of two, as is done in the linker. This replaces the Align field in FuncInfo.

2026-01-26cmd/compile: reduce lock/scheduler contentionDaniel Morsing
During the parallel section of compilation, we limit the amount of parallelism to prevent scheduler churn. We do this with a worker scheduler, but it does not have insight on when a compilation is blocked due to lock contention. The symbol table was protected with a lock. While most lookups were quick lock->read->unlock affairs, sometimes there would be initialization logic involved. This caused every lookup to stall, waiting for init. Since our worker scheduler couldn't see this, it would not launch new goroutine to "cover" the gap. Fix by splitting the symbol lock into 2 cases, initialization and lookup. If symbols need initialization simultaneously, they will wait for each other, but the common case of looking up a symbol will be handled by a syncmap. In practice, I have yet to see this lock being blocked on. Additionally, get rid of the scheduler goroutine and have each compilation goroutine grab work from a central queue. When multiple compilations finished at the same time, the work scheduler would sometime not get run immediately. This ended up starving the system of work. These 2 changes together cuts -1.37% off the build time of typescriptgo on systems with a lot of cores (specifically, the c3h88 perf builder). Updates #73044.

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.

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.

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.

This special case was added in CL 310171 for test/run.go use, as the comment still says, but run.go (cmd/internal/testdir/testdir_test.go by now) stopped using this in CL 310732. There don't seem to be any other internal or external uses of this special case, so delete it. Doing this kind of a cleanup can become harder as more time passes, so try it as early as now and see how it goes.

In dynlink mode, we rewrite reference to a global variable to a load from the GOT. Currently this code does not handle the case that the global reference is in From3 of a Prog. Most instructions don't expect a memory operand in From3, but some do, like VGF2P8AFFINEQB. Handle this case.

2025-11-18cmd/asm,cmd/compile,cmd/internal/obj/riscv: use compressed instructions on ↵Joel Sing
riscv64 Make use of compressed instructions on riscv64 - add a compress pass to the end of the assembler, which replaces non-compressed instructions with compressed alternatives if possible. Provide a `compressinstructions` compiler and assembler debug flag, such that the compression pass can be disabled via `-asmflags=all=-d=compressinstructions=0` and `-gcflags=all=-d=compressinstructions=0`. Note that this does not prevent the explicit use of compressed instructions via assembly. Note that this does not make use of compressed control transfer instructions - this will be implemented in later changes. Reduces the text size of a hello world binary by ~121KB and reduces the text size of the go binary on riscv64 by ~1.21MB (between 8-10% in both cases).

2025-11-17cmd/internal/sys,internal/goarch,runtime: enable the use of compressed ↵Joel Sing
instructions on riscv64 Enable the use of compressed instructions on riscv64 by reducing the PC quantum to two bytes and reducing the minimum instruction length to two bytes. Change gostartcall on riscv64 to land at two times the PC quantum into goexit, so that we retain four byte alignment and revise the NOP instructions in goexit to ensure that they are never compressed. Additionally, adjust PCALIGN so that it correctly handles two byte offsets.

We have cherry-picked the changes to prove.go to main branch, so our copy is identical to an old version of the one on the main branch. There are CLs landed after our cherry-picks.

2025-11-13cmd/asm,cmd/internal/obj/riscv: add support for riscv compressed instructionsJoel Sing
Add support for compressed instructions in the RISC-V assembler. This implements instruction validation and encoding for all instructions in the "C" extension. It is worth noting that the validation and encoding of these instructions is far more convoluted then the typical instruction validation and encoding. While the current model has been followed for now, it would be worth revisiting this in the future and potentially switching to a table based or even per-instruction implementation. Additionally, the current instruction encoding is lacking some of the bits needed for compressed instructions - this is solved by compressedEncoding, which provides the missing information. This will also be addressed in the future, likely by changing the instruction encoding format.

2025-11-13cmd/internal/obj/riscv: implement better bit pattern encodingJoel Sing
Replace the extractBitAndShift function with an encodeBitPattern function. This allows the caller to specify a slice of bits that are to be extracted and encoded, rather than making multiple function calls and combining the results.

This change mechanically replaces all occurrences of interface{} by 'any' (where deemed safe by the 'any' modernizer) throughout std and cmd, minus their vendor trees. Since this fix is relatively numerous, it gets its own CL. Also, 'go generate go/types'.

2025-11-10cmd/internal/obj/arm64: shorten constant integer loadsKeith Randall
Large integer constants can take up to 4 instructions to encode. We can encode some large constants with a single instruction, namely those which are bit patterns (repetitions of certain runs of 0s and 1s). Often the constants we want to encode are *close* to those bit patterns, but don't exactly match. For those, we can use 2 instructions, one to load the close-by bit pattern and one to fix up any mismatches. The constants we use to strength reduce divides often fit this pattern. For unsigned divides by 1 through 15, this CL applies to the constant for N=3,5,6,10,12,15. Triggers 17 times in hello world.
