[docs] Remove POD based man page docs (and build system support).
- Currently this leaves us with less build system support (e.g., installing man pages) for the docs than is desired. I'm working on fixing this, but it may take a while. If someone finds this particularly egregious let me know and I will prioritize it.

Insignificant -differences, such as changes in the ordering of globals or in the -names of local values, are ignored. - -An input module will be interpreted as an assembly file if its name -ends in '.ll'; otherwise it will be read in as a bitcode file. - -If a list of global names is given, just the values with those names -are compared; otherwise, all global values are compared, and -diagnostics are produced for globals which only appear in one module -or the other. - -B<llvm-diff> compares two functions by comparing their basic blocks, -beginning with the entry blocks. If the terminators seem to match, -then the corresponding successors are compared; otherwise they are -ignored. This algorithm is very sensitive to changes in control flow, -which tend to stop any downstream changes from being detected. - -B<llvm-diff> is intended as a debugging tool for writers of LLVM -passes and frontends. It does not have a stable output format. - -=head1 EXIT STATUS - -If B<llvm-diff> finds no differences between the modules, it will exit -with 0 and produce no output. Otherwise it will exit with a non-zero -value. - -=head1 BUGS - -Many important differences, like changes in linkage or function -attributes, are not diagnosed. - -Changes in memory behavior (for example, coalescing loads) can cause -massive detected differences in blocks. - -=head1 AUTHORS - -Maintained by the LLVM Team (L<http://llvm.org/>). - -=cut |
