How to dynamically allocate memory and IO in RISC-V simulator?

[cla7aye15I4nd]

If use a simulator to run RISCV code, how to implement input, output and dynamically allocate memory ? These operations seem to depend on the operating system.

@cla7aye15I4nd Hello, I am the one who is implementing the simulator. You can assume that some common C functions such as malloc, scanf, printf, etc. are implemented in the simulator. Namely, to implement the builtin functions, you can simply write a C file like this one https://github.com/Engineev/mocker/blob/master/builtin/builtin.c.
