cmd/gc: reduce lexer allocs when parsing numeric constants This reduces the number of allocs when running the rotate.go tests by about 20%, after applying CL 5700. Combining s = "const str" s += <another string> generally saves an alloc and might be a candidate for rsc's grind tool. However, I'm sending this CL now because this also reuses the result of calling lexbuf.String.

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
