For posterity: I've 'pushed' for this upstream in dlang/dmd#20964, but turns out GDC doesn't use that upstream So thx Dennis for bearing with me. |

This code is based on mine earlier implementation for
rv32, so both platforms should be supported:rv32andrv64with and without compressed instructions and with and withoutHardFloat.For now it is tested only on
rv64withHardFloat(QEMU, Ubuntu 24.10,ldc2from~master)Implemented using separate file because I see potential for growth of this assembly code (I want to implement embedded ISA subset and maybe something vendor-specific), and also to put an end to
viciousscaring me practice of putting assembly code for completely different platforms into one huge .S filePath to the new asm file is the same as in the current DMD
