<p>LLVM debugging information has been carefully designed to make it possible
for the optimizer to optimize the program and debugging information without
necessarily having to know anything about debugging information. In
- particular, te use of metadadta avoids duplicated dubgging information from
+ particular, the use of metadata avoids duplicated debugging information from
the beginning, and the global dead code elimination pass automatically
deletes debugging information for a function if it decides to delete the
function. </p>
<p>To provide basic functionality, the LLVM debugger does have to make some
assumptions about the source-level language being debugged, though it keeps
these to a minimum. The only common features that the LLVM debugger assumes
- exist are <a href="#format_compile_units">source files</a>,

and <a href="#format_global_variables">program objects</a>. These abstract
objects are used by a debugger to form stack traces, show information about
local variables, etc.</p>
of tags are loosely bound to the tag values of DWARF information entries.
However, that does not restrict the use of the information supplied to DWARF
targets. To facilitate versioning of debug information, the tag is augmented
- with the current debug version (LLVMDebugVersion = 7 << 16 or 0x70000 or
- 458752.)</a></p>

-<p>Each input file is encoded as a separate compile unit in LLVM debugging

- code generator will include debugging information entities in the compile
- unit that is marked as main compile unit. The code generator accepts maximum
