make all-gdb and make install-gdb are faster fwiw (and need less deps installed)
This is what I use on a mac:
make all-gdb -j8 CXXFLAGS="-w -g" CFLAGS="-g" && make install-gdb &&
codesign -s gdb-cert ~/gdb/bin/gdb
(need to ignore warnings because clang. Remove the -g if you're not
hacking on gdb
If you're on Linux, GDB 7.12 has Rust support. Fedora hasn't packaged that
yet, but I did this to get a fresh GDB that I can run from ~/gdb/bin:
sudo dnf builddep binutils gdb
mkdir ~/gdb
cd ~/gdb
git clone git://sourceware.org/git/binutils-gdb.git
mkdir build
cd build
../binutils-gdb/configure --
First, make sure you're running XCode 8, since the lldb in XCode 7 is

XCode 8 beta as a workaround, and then forgot about it. XCode 8 came out a
while ago, but it doesn't auto-update.
Second, the Rust optimization level for d
