cmd/internal/gc: registerize more in 7g and 9g 7g and 9g disagree with componentgen about what type len and cap have. This results in an etype mismatch, which inhibits registerization. Fixing this results in 7406 more registerizations while building the stdlib. There are still 1512 missed opportunities. This should improve the performance benefit to 7g of enabling componentgen (CL 8636). This CL reduces the size of godoc by 203k (-1.177%). This was discovered by using the diagnostics added in CL 8732 and running: GOARCH=arm64 GOOS=linux go build -gcflags="-d registerization" std See CL 91850043 for similar earlier fixes for 6g and 8g.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
