I'm trying to compile llvm-17 on riscv, and every time I try the build fails as follows:

That's all the error message I get. I tried going into the working dir and running the

in the working directory that emerge leaves behind. That ran successfully
I also cloned the llvm repo and built it, which ran successfully. This failure only seems to happen when running emerge. I cannot reproduce it otherwise.
I have tried removing the `-pipe` from my make.conf. Failure still remained.
I have tried installing a different version (18.1.3). Failure still remained.
What could be the problem? |

We would need to see the rest of the build log. Put it in a pastebin site if you want help.

Anything interesting in dmesg's output?
I could imagine there being a llvm-tblgen segmentation fault, ninja's build.log has a tendency to hide that these happened.
If manual build succeed, may be related to C(XX)FLAGS given I assume you haven't been using them for the manual build (even "safe" flags like -march can have unexpected results on lesser tested platforms). Alternatively, it could be something up with sandbox on riscv (could try FEATURES="-sandbox -usersandbox" to test). The ebuild will also be passing all sort of flags and enable/disable features so it could be something specific. |

Ah that makes sense. Wouldn't've thought of checking dmesg... Thanks for the tip, will set up a swap file. |

| After a few more failed attempts (removing the `-pipe` argument while compiling on a tmpfs surprisingly didn't fix it), llvm compiled without issues now. |
