2025-11-03cmd/internal/obj: support arm64 FMOVQ large offset encodingAlexander Musman
Support arm64 FMOVQ with large offset in immediate which is encoded using register offset instruction in opldrr or opstrr. This will help allowing folding immediate into new ssa ops FMOVQload and FMOVQstore. For example: FMOVQ F0, -20000(R0) is encoded as following: MOVD 3(PC), R27 FMOVQ F0, (R0)(R27) RET ffff b1e0 # constant value Change-Id: Ib71f92f6ff4b310bda004a440b1df41ffe164523 Reviewed-on: https://go-review.googlesource.com/c/go/+/716960 Reviewed-by: Cherry Mui <cherryyz@google.com> Auto-Submit: Michael Pratt <mpratt@google.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Michael Pratt <mpratt@google.com>
2025-11-02cmd/go: skip git sha256 tests if git < 2.29David Finkel
Fix test building on older Ubuntu LTS releases (that are still supported). Git SHA256 support was only included in 2.29, which came out in 2021. Check the output of `git version` and skip these tests if the version is older than that introduction. Thanks to @ianlancetaylor for flagging this.

2025-10-29test/codegen: simplify asmcheck pattern matchingRuss Cox
Separate patterns in asmcheck by spaces instead of commas. Many patterns end in comma (like "MOV [$]123,") so separating patterns by comma is not great; they're already quoted, so spaces are fine. Also replace all tabs in the assembly lines with spaces before matching. Finally, replace \$ or \\$ with [$] as the matching idiom. The effect of all these is to make the patterns look like: // amd64:"BSFQ" "ORQ [$]256" instead of the old: // amd64:"BSFQ","ORQ\t\\$256" Update all tests as well.

2025-10-29runtime: use internal/strconvRuss Cox
Runtime doing its own number formatting dates back to when runtime was the bottom-most Go package. Those days are long gone. Use internal/strconv to avoid duplicating code and also to get better floating-point formatting: % go1.24.6 run x.go +1.234568e+004 % go run x.go 12345.678 % With accurate floating point it becomes necessary to introduce separate printers for float32 vs float64 and for complex64 vs complex128. Otherwise float32(93.7) prints as 93.69999694824219.

2025-10-14cmd/internal/obj/arm64: add support for PAC instructionsBill Roberts
Add support for the Pointer Authentication Code instructions required for the ELF ABI when enabling PAC aware binaries. This allows for assembly writers to add PAC instructions where needed to support this ABI. Follow up work is to enable the compiler to emit these instructions in the appropriate places. The TL;DR for the Linux ABI is that the prologue of a function that pushes the link register (LR) to the stack, signs the LR with a key managed by the operating system and hardware using a PAC instruction, like "paciasp". The function epilog, when restoring the LR from the stack will verify the signature, using an instruction like "autiasp". This helps prevents attackers from modifying the return address on the stack, a common technique for ROP attacks. Details on PAC can be found here: - https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/enabling-pac-and-bti-on-aarch64 - https://developer.arm.com/documentation/109576/0100/Pointer-Authentication-Code The ABI details can be found here: - https://github.com/ARM-software/abi-aa/blob/main/aaelf64/aaelf64.rst Change-Id: I4516ed1294d19f9ff9d278833d542821b6642aa9 Reviewed-on: https://go-review.googlesource.com/c/go/+/676675 Reviewed-by: Cherry Mui <cherryyz@google.com> Reviewed-by: Joel Sing <joel@sing.id.au> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Dmitri Shuralyov <dmitshur@google.com>

2025-10-06cmd/compile: redo arm64 LR/FP save and restoreKeith Randall
Instead of storing LR (the return address) at 0(SP) and the FP (parent's frame pointer) at -8(SP), store them at framesize-8(SP) and framesize-16(SP), respectively. We push and pop data onto the stack such that we're never accessing anything below SP. The prolog/epilog lengths are unchanged (3 insns for a typical prolog, 2 for a typical epilog). We use 8 bytes more per frame. Typical prologue: STP.W (FP, LR), -16(SP) MOVD SP, FP SUB $C, SP Typical epilogue: ADD $C, SP LDP.P 16(SP), (FP, LR) RET The previous word where we stored LR, at 0(SP), is now unused. We could repurpose that slot for storing a local variable. The new prolog and epilog instructions are recognized by libunwind, so pc-sampling tools like perf should now be accurate. (TODO: except maybe after the first RET instruction? Have to look into that.)

2025-09-16cmd/internal/obj/riscv: improve handling of float point movesJoel Sing
Translate moves from an integer register to a floating point register, or from a floating point register to an integer register, to the appropriate move instruction (i.e. FMVXW/FMVWX/FMVXD/FMVDX). Add support for MOVF with a constant - we previously added support for MOVD but not for MOVF. Add special handling for 0.0, which we can translate to a move from the zero register to a floating point register (leveraging the above mentioned change).

2025-09-16[dev.simd] cmd/compile: use the right type for spill slotCherry Mui
Currently, when shuffling registers, if we need to spill a register, we always create a spill slot of type int64. The type doesn't actually matter, as long as it is wide enough to hold the registers. This is no longer true with SIMD registers, which could be wider than a int64. Create the slot with the proper type instead.

This was limited to just the mainline linux-amd64 builder, but we don't use that name anymore. Use the LUCI name instead, gotip-linux-amd64.

2025-09-12cmd/asm, cmd/internal/obj: add riscv64 generic CSR opsMark Ryan
Support is added for the generic RISC-V CSR operations; CSRRC, CSRRCI, CSRRS, CSRRSI, CSRRW, CSRRWI. These instructions require special handling as their second operand is a symbolic CSR register name and not an immediate value or a register. CSR names are implemented as special operands. RISC-V CSRs are not currently saved and restored when a go routine is asynchronously pre-empted so it is only safe to use these instructions in hand written assembler. Note that CSRRS was already partially supported by the assembler so this restriction predates this commit. We mention it here as this commit makes CSRRS much easier to use.
