I tried LLDB on Ubuntu 12.04, only to find out that it has multiples bugs and no one cares. So no.
My current standing is to use whichever compiler and debugger your platform comes default with: msvc/cdb for Windows, gcc/gdb for Linux and clang/lldb for OS X. Crossing them always reveals tons of bugs, at least for me.
On osx, perhaps. On Linux it's still a little rough. Or was last time I tried to use it. That said, I do look forward to using it more. But most importantly, I look forward to the tooling that can be built around it, since it's much easier to treat it as a library than gdb.
I heard they recently bit the bullet and implemented GDB/MI so lldb can be used by all mainstream IDEs. This doesn't stop lldb-specific targets in IDEs, but it does make them less likely is my guess.
Copying `/usr/bin/gdb` and `/usr/libexec/gdb/gdb-i386-apple-darwin` from an OSX Lion installation is one way to get a functional gdb on Mountain Lion or Yosemite.
