Original issue's description: > Don't link with audio codecs that we don't use > > We used to link with all audio codecs unconditionally (except Opus); > this patch makes gyp and gn only link to the ones that are used. > > (This unfortunately fails to have a measurable impact on Chromium > binary size, at least on x86_64 Linux; it turns out that iLBC and iSAC > fix were already being excluded from Chromium by some other means > (likely just the linker omitting compilation units with no incoming > references).) > > BUG=webrtc:4557 > > Committed: https://crrev.com/f66a9251424351ea6d631c54dd1feb64cc13d809 > Cr-Commit-Position: refs/heads/master@{#10046} TBR=henrik.lundin@webrtc.org,tina.legrand@webrtc.org,kjellander@webrtc.org,kwiberg@webrtc.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=webrtc:4557 Review URL: https://codereview.webrtc.org/1368933002 Cr-Commit-Position: refs/heads/master@{#10069}
