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 : -
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.
