Hello, On Thu, May 23, 2013 at 10:14 AM, Claudio Fontana <claudio.fontana@huawei.com> wrote: > > we will use the 26bit relative relocs in the aarch64 tcg target. Is there really any point in adding all of the relocation types? i386 doesn't, mips doesn't, x86_64 doesn't. I didn't check the others. I guess we can at least get rid of dynamic relocs.
