What are the equivalent ldc2 parameters for clang -march=rv32g_zba_zbb_zbc_zbs?

[calvin2021y]

pass --march=rv32g_zba_zbb_zbc_zbs to ldc2 get error: invalid target architecture 'rv32g_zba_zbb_zbc_zbs', see -version for a list of supported targets.

I'm not sure what the g in rv32g means but, for the rest, you can use:

ldc2 -march riscv32 -mattr=+zba,+zbb,+zbc,+zbs
