2011-04-05Added *hidden* flags -print-options and -print-all-options soAndrew Trick
developers can see if their driver changed any cl::Option's. The current implementation isn't perfect but handles most kinds of options. This is nice to have when decomposing the stages of compilation and moving between different drivers. It's also a good sanity check when comparing results produced by different command line invocations that are expected to produce the comparable results. Note: This is not an attempt to prolong the life of cl::Option. On the contrary, it's a placeholder for a feature that must exist when cl::Option is replaced by a more appropriate framework. A new framework needs: a central option registry, dynamic name lookup, non-global containers of option values (e.g. per-module, per-function), *and* the ability to print options values and their defaults at any point during compilation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128910 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Constants with multiple encodings (ARM):Johnny Chen
An alternative syntax is available for a modified immediate constant that permits the programmer to specify the encoding directly. In this syntax, #<const> is instead written as #<byte>,#<rot>, where: <byte> is the numeric value of abcdefgh, in the range 0-255 <rot> is twice the numeric value of rotation, an even number in the range 0-30. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128897 91177308-0d34-0410-b5e6-96231b3b80d8
