Comment 1 AK 2023-09-14 23:06:06 UTC 
I got this error while building clang (ninja clang) on a riscv machine.

Comment 2 Andrew Pinski 2023-09-14 23:18:11 UTC 
This might be a binutils bug ...
Comment 3 Andrew Pinski 2023-09-14 23:30:51 UTC 
Or just this function is huge for -O0 in which case riscv does not have a good code model for that case
Comment 4 AK 2023-09-14 23:41:43 UTC 
good catch. By mistake i built at -O0, i wanted to build at -O3.
Comment 6 AK 2023-09-15 16:35:49 UTC 
To confirm what Andrew mentioned, the release build (-O3) built successfully.
