From 0a48860c27a8eb291bcc7616ea9eb073dc660cab Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 24 May 2019 10:46:08 -0400 Subject: add riscv64 architecture support Author: Alex Suykov Author: Aric Belsito Author: Drew DeVault Author: Michael Clark Author: Michael Forney Author: Stefan O'Rear This port has involved the work of many people over several years. I have tried to ensure that everyone with substantial contributions has been credited above; if any omissions are found they will be noted later in an update to the authors/contributors list in the COPYRIGHT file. The version committed here comes from the riscv/riscv-musl repo's commit 3fe7e2c75df78eef42dcdc352a55757729f451e2, with minor changes by me for issues found during final review: - a_ll/a_sc atomics are removed (according to the ISA spec, lr/sc are not safe to use in separate inline asm fragments) - a_cas[_p] is fixed to be a memory barrier - the call from the _start assembly into the C part of crt1/ldso is changed to allow for the possibility that the linker does not place them nearby each other. - DTP_OFFSET is defined correctly so that local-dynamic TLS works - reloc.h LDSO_ARCH logic is simplified and made explicit. - unused, non-functional crti/n asm files are removed. - an empty .sdata section is added to crt1 so that the __global_pointer reference is resolvable. - indentation style errors in some asm files are fixed. --- arch/riscv64/bits/socket.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 arch/riscv64/bits/socket.h (limited to 'arch/riscv64/bits/socket.h') diff --git a/arch/riscv64/bits/socket.h b/arch/riscv64/bits/socket.h new file mode 100644 index 00000000..aae537d3 --- /dev/null +++ b/arch/riscv64/bits/socket.h @@ -0,0 +1,19 @@ +#include + +struct msghdr { + void *msg_name; + socklen_t msg_namelen; + struct iovec *msg_iov; + int msg_iovlen, __pad1; + void *msg_control; + socklen_t msg_controllen; + int __pad2; + int msg_flags; +}; + +struct cmsghdr { + socklen_t cmsg_len; + int __pad1; + int cmsg_level; + int cmsg_type; +}; -- cgit v1.2.1
