The Go programming language
70138a2108
The uint64 divide function calls _mul64x32 to do a 64x32-bit multiply and then compares the result against the 64-bit numerator. If the result is bigger than the numerator, must use the slow path. Unfortunately, the 64x32 produces a 96-bit product, and only the low 64 bits were being used in the comparison. Return all 96 bits, the bottom 64 via the original uint64* pointer, and the top 32 as the function's return value. Fixes 386 build (broken by ARM division tests).

Binary Distribution Notes
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 README). 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.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
See doc/install.html for more details.
