[go-nuts] Build fails when using gollvm toolchain instead of go
Hi, I've been trying to make this project https://github.com/intel-go/nff-go using a freshly built gollvm to get the code compiled into LLVM IR. The project builds fine when using the regular go toolchain, but when trying to build with gollvm, I get errors such as below: ../../asm/asm.s: Assembler messages: ../../asm/asm.s:6: Error: no such instruction: `text ·RteCompilerRmb(SB),NOSPLIT,$0-0' ../../asm/asm.s:9: Error: no such instruction: `text ·RteCompilerWmb(SB),NOSPLIT,$0-0' ../../asm/asm.s:12: Error: no such instruction: `text ·Prefetcht0(SB),NOSPLIT,$0-8' ../../asm/asm.s:13: Error: junk `(FP)' after expression ../../asm/asm.s:13: Error: too many memory references for `movq' ../../asm/asm.s:16: Error: no such instruction: `text ·GenerateMask(SB),NOSPLIT,$0-33' ../../asm/asm.s:17: Error: junk `(FP)' after expression ../../asm/asm.s:17: Error: too many memory references for `movq' ../../asm/asm.s:18: Error: junk `(FP)' after expression ../../asm/asm.s:18: Error: too many memory references for `movq' ../../asm/asm.s:19: Error: junk `(FP)' after expression ../../asm/asm.s:19: Error: too many memory references for `movq' ../../asm/asm.s:20: Error: junk `(FP)' after expression ../../asm/asm.s:20: Error: too many memory references for `movq' ../../asm/asm.s:21: Error: too many memory references for `vmovdqu' ../../asm/asm.s:22: Error: too many memory references for `vmovdqu' ../../asm/asm.s:23: Error: too many memory references for `vmovdqu' ../../asm/asm.s:24: Error: too many memory references for `vpcmpeqb' ../../asm/asm.s:25: Error: too many memory references for `vpand' ../../asm/asm.s:26: Error: too many memory references for `vptest' ../../asm/asm.s:27: Error: junk `(FP)' after expression ../../asm/asm.s:27: Error: invalid instruction suffix for `sete' ../../asm/asm.s:28: Error: too many memory references for `vmovdqu' -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Build fails when following build instructions
Hi, I initially opened an issue, but was suggested to post to the mailing list instead: https://github.com/golang/go/issues/38728 Build keeps failing when trying to build (Ubuntu Focal Fossa, amd64) from the latest commit to the master and following the build instructions. Has anyone succeeded to build gollvm recently? I am getting errors like this: -- Could NOT find LibXml2 (missing: LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) -- Native target architecture is X86 -- Threads enabled. -- Doxygen disabled. -- Go bindings disabled. -- Ninja version: 1.10.0 -- Could NOT find OCaml (missing: OCAMLFIND OCAML_VERSION OCAML_STDLIB_PATH) -- Could NOT find OCaml (missing: OCAMLFIND OCAML_VERSION OCAML_STDLIB_PATH) -- OCaml bindings disabled. -- LLVM host triple: x86_64-unknown-linux-gnu -- LLVM default target triple: x86_64-unknown-linux-gnu -- Building with -fPIC -- Constructing LLVMBuild project information -- Targeting AArch64 -- Targeting AMDGPU -- Targeting ARM -- Targeting AVR -- Targeting BPF -- Targeting Hexagon -- Targeting Lanai -- Targeting Mips -- Targeting MSP430 -- Targeting NVPTX -- Targeting PowerPC -- Targeting RISCV -- Targeting Sparc -- Targeting SystemZ -- Targeting WebAssembly -- Targeting X86 -- Targeting XCore CMake Error at tools/gollvm/cmake/modules/AddGollvm.cmake:37 (message): C compiler does not support -fsplit-stack Call Stack (most recent call first): tools/gollvm/CMakeLists.txt:21 (include) -- starting libgo configuration.
