Hi all, I have a question in SO regarding parameter passing in ELF binaries:
https://stackoverflow.com/questions/70150497/go-binaries-parameter-passing One of the comments referenced me to this mailing list, so I'm re-posting here: I’m trying to understand parameter passing in go ELF binaries mov %rdi,0x8(%rsp) <----- first parameter (?) mov %r8,0x10(%rsp) <----- second mov %r9,0x18(%rsp) <----- third mov %r10,0x20(%rsp) <----- fourth mov %rcx,0x28(%rsp) <----- fifth sub %edx,%ebx movslq %ebx,%rcx mov %rcx,0x30(%rsp) <----- sixth callq 5aaba0 <math/big.nat.shl> <----- call to native golang func It seems that parameters are passed on stack, but when I look at the function here (line 681) <https://go.dev/src/math/big/nat.go>: // z = x << s func (z nat) shl(x nat, s uint) nat { ... } The number of parameter is just *2*, and in the ELF it looks like *6* (?) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
