splitdwarf: initial working commit

splitdwarf osxMachoFile [ osxDsymFile ]

splitdwarf takes an executable produced by go build as input,
and uncompresses and copies the DWARF segment into a separate
file in the way that is expected by OSX-hosted tools
(lldb and ports of gdb).
If osxDsymFile is not named explicitly, the default of
"<osxMachoFile>.dSYM/Contents/Resources/DWARF/<osxMachoFile>"
is used instead, with directories created as needed.

If the input file contains no UUID, then one is created by
hashing non-DWARF segment contents, and added to the
executable. This is necessary because gdb and lldb both
expect matching UUIDs to be present in the executable
and its debugging symbols.

Includes a modified version of debug/macho, with additional
definitions and the ability to write segments, sections, and
some MachO load commands added.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
