[llvm-commits] inline assembly operand type MEMUSE

[Florian Brandner]

hi,

i've added a new type of inline assembly operands called MEMUSE, for 'm'
constraints that only read from memory.

in addition, i created an enum - InlineAsmFlags - of all possible operand
types (REGUSE, REGDEF, IMMUSE. MEMUSE, MEMDEF) and two global constants
InlineAsmMask and InlineAsmShift to extract these flags and the machine
operand count.

i've tested it on a llvm 2.0 based private backend and a test
application with lots of inline assembly. i did not test llvm-trunk very
carefully because of lacking applications that use inline assembly - my
handcrafted test cases work though.
