This patch series introduces a port of GCC to eBPF, which is a virtual machine that resides in the Linux kernel. Initially intended for user-level packet capture and filtering, eBPF is nowadays generalized to serve as a general-purpose infrastructure also for non-networking purposes. The binutils support is already upstream. See https://sourceware.org/ml/binutils/2019-05/msg00306.html. ChangeLog: * MAINTAINERS: Add myself as the maintainer of the eBPF port. Remove myself from Write After Approval section. * configure.ac: Support for bpf-*-* targets. * configure: Regenerate. contrib/ChangeLog: * config-list.mk (LIST): Disable go in bpf-*-* targets. gcc/ChangeLog: * doc/invoke.texi (Option Summary): Cover eBPF. (eBPF Options): New section. * doc/extend.texi (BPF Built-in Functions): Likewise.
