llvm-11.1.0 build failed on Loongarch #4

Closed darkgeek closed 2 years ago

Hi,

I use your 1205 version of stage3 on my 3A5000, and have upgraded my world to the latest. However, when I tried to build llvm-11.1.0 (introduced by mesa), it failed with the following errors:

Not sure how to figure it out. Could you help me, please? If you need more information, I'd provide ASAP. Thanks.

Hi, this is a known problem; it seems the bootstrapped toolchain has some very deep bug that doesn't exist in the cross-compiled toolchains. I tried but haven't had any clue yet.

I find that, by removing AMDGPU and ARM targets from the ebuild, llvm can be built successfully:

Although it works for some people like me (who don't need AMDGPU and ARM), it's only a dirty workaround and far from perfect.

Fixed by loongson/gcc#77, can confirm llvm builds flawlessly now. Thanks!
