* [ms-inline asm] Add support for lexing binary integers with a [bB] suffix.Chad Rosier2013-02-121-19/+40
| | | | | | | | | | | | | | | This is complicated by backward labels (e.g., 0b can be both a backward label and a binary zero). The current implementation assumes [0-9]b is always a label and thus it's possible for 0b and 1b to not be interpreted correctly for ms-style inline assembly. However, this is relatively simple to fix in the inline assembly (i.e., drop the [bB]). This patch also limits backward labels to [0-9]b, so that only 0b and 1b are ambiguous.
