--- Comment #4 from Alexander von Gluck IV <kallisti5 at unixzen dot com> ---
Here's our riscv config for Haiku:
https://git.haiku-os.org/buildtools/tree/gcc/gcc/config/riscv/haiku.h

Anything beyond that is "stuff working on other architectures"


The linker script definitely needs work (and is likely wrong), however passing
an empty file to --script results in a segfault.

Test file:
$ cat test.c
#include <stdio.h>
int main()
{
        printf("hi!\n");
        return 0;
}


Linux x86:

$ gcc test.c -o test.o
$ touch test.ld
$ ld --script=test.ld test.o -o test
ld: error in test.o(.eh_frame); no .eh_frame_hdr table will be created
ld: test: not enough room for program headers, try linking with -N
ld: final link failed: bad value
