Hi,
has anyone tied building EDK2 (e.g. MdePkg) for RiscV64 with gcc 12?
I get:

/edk2/Build/Mde/DEBUG_GCC5/RISCV64/MdePkg/Library/BaseLib/BaseLib/OUTPUT/Ri= scV64/FlushCache.iiii:16: Error: unrecognized opcode `fence.i'

I found this gcc bug:
Bug 104853 - [RISC-V] -march=3Drv64g not including extension Zifencei
https://g= cc.gnu.org/bugzilla/show_bug.cgi?id=3D104853

I was working on getting gcc 12 into the CI.

Thanks,
