Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |MOVED Status|UNCONFIRMED |RESOLVED --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- >Assembler messages: /home/akhilesh.k/git/riscv-crypto/build/benchmarks/rv64-zscrypto/include/riscvcrypto/share/rvintrin.h:151: Error: unrecognized opcode `greviw t3,t3,24' This error message is from the assembler. GCC does not directly contain the assembler, you need to report this to binutils since I suspect you got the assembler from there. (https://sourceware.org/bugzilla/ ).
