Subject: [PATCH RFC v4 net-next 22/26] bpf: llvm backend
Date: Wed, 13 Aug 2014 00:57:33 -0700 [thread overview]
Message-ID: <1407916658-8731-23-git-send-email-ast@plumgrid.com> (raw)
In-Reply-To: <1407916658-8731-1-git-send-email-ast@plumgrid.com>
llvm backend that generated eBPF and emits either
binary ELF or human readable eBPF assembler
Signed-off-by: Alexei Starovoitov <ast@plumgrid.com>
---
the body of the patch is removed to prevent spam.
I doubt too many falks are interested in reading llvm diffs on lkml.
The backend is available in the tree:
