Asiri Rathnayake dc05f3a64b Add support for ARM modified-immediate assembly syntax. ... Certain ARM instructions accept 32-bit immediate operands encoded as a 8-bit integer value (0-255) and a 4-bit rotation (0-30, even). Current ARM assembly syntax support in LLVM allows the decoded (32-bit) immediate to be specified as a single immediate operand for such instructions: mov r0, #4278190080 The ARMARM defines an extended assembly syntax allowing the encoding to be made more explicit, as in: mov r0, #255, #8 ; (same 32-bit value as above) The behaviour of the two instructions can be different w.r.t flags, which is documented under "Modified immediate constants" in ARMARM. This patch enables support for this extended syntax at the MC layer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223113 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-02 10:53:20 +00:00
