Help in pointing to correct pattern in md file

[rohitgeek]

I am trying on ARM processor to check on how complex instruction works, but
not getting the expected result.

In arm.md, a pattern for MLA instruction is present which should be used to
emit the instruction " mla  ________ " if i write the test code as : -

main()
  {
  int a,b,c;
  a=10; b=5; c=7;
  a = b*c +b;  //MLA
}

The result is that i get two different instructions. What should in done in
md files or build/compile time to support these kind of instructions.

Thanks
