Copying sym.Reloc in loops hurts performance as it has 48 byte size (on 64-bit platforms). There are quite many symbols and each of them has more than 1 relocation (so, it's possible to have more than 1kk relocs). The're also traversed more than once in some code paths. By using pointers to them, copies are avoided. For linking "hello world" example from net/http: name old time/op new time/op delta Linker-4 530ms ± 2% 521ms ± 3% -1.80% (p=0.000 n=17+20) Change-Id: I6518aec69d6adcd137f84b5c089ceab4cb4ea2dd Reviewed-on: https://go-review.googlesource.com/113636 Run-TryBot: Iskander Sharipov <iskander.sharipov@intel.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> |
