I haven't encountered this issue before. Maybe there where some deletions, like in case of #32381.

The GoLLVM build files will likely need some updating for the update to the go1.15rc1 release that I committed earlier today.

For this particular problem you probably just need to s/cpu_gccgo/cpu_gccgo_x86/. I don't know if there will be other problems.

Hey @ianlancetaylor
I found this piece of code

if (NOT ${goarch} STREQUAL "arm64")
  list(APPEND runtimecfiles
    "go/golang.org/x/sys/cpu/cpu_gccgo.c")
endif()

while looking at the source of go/golang.org/x/sys/cpu/ i found cpu_gccgo with arm64 and x86, considering the arch check you want to replace it with go/golang.org/x/sys/cpu/cpu_gccgo_x86.c

I can probably create a fix for this.

Thanks, @aaqaishtyaq . I was able to build against x86, ARM, AArch64 and RISC-V before.
So I think some of the architectures have to be configured properly, to allow the build process.
@tmaczukin , please take a look at this.

Solves nothing for ARM32, ARM64 or RISC-V architectures - but allows me to get this:

As far as I know GoLLVM only works on amd64 GNU/Linux.

I have extended it to arm64 gnu/linux. Currently split-stack is not supported on arm64, and there may be some failed tests.

cpu_gccgo_x86.go

Didn't try locally, but if cpu_gccgo.go is the root cause, you may want to add the arch-dependent version for both ARM64 and AMD64 for now, and other architectures later when they are supported.

if (NOT ${goarch} STREQUAL "arm64")
list(APPEND runtimecfiles

endif()

should be

if (NOT ${goarch} STREQUAL "arm64")
list(APPEND runtimecfiles
"go/golang.org/x/sys/cpu/cpu_gccgo_x86.c")
endif()

And it is recommended to build with an old version of llvm, the latest one may have synchronization problems. I use a61fa1a4b9d

Solves nothing for ARM32, ARM64 or RISC-V architectures - but allows me to get this:

You may want to turn on the verbosity of cmake if needed, cmake .... --debug-output --trace (or --trace-expand) ...
