Why does a simple or empty Hello program generate a lot of
assembly output for the risc-v architecture, but not for the
ARM and X86 architectures?
Need an example.
A helloworld program on the X86_64-pc-linux-gnu platform
contains 40 lines of assembly code or on the ARM
(aarch64-linux-gnu) platform only 34 lines of assembly code,
but on the risc-v(riscv64-unknow-gnu-linux) platform contains
871 lines of code on the explore.dgnu.org site!
I'm concerned that this will affect the performance of the
risc-v platform.
A Phobos helloworld is over 1000 lines of assembly on both x86_64
and ARM64. My guess is that Compiler Explorer isn't smart enough
to filter RISC-V assembly in the same way as ARM or X86.
