Generate Register Indirect mode instruction
...t few examples to understand
backend codegen. I have ported llvm LEG @
https://github.com/frasercrmck/llvm-leg to llvm 3.9 successfully.
Currently, the LEG instructions are RISC load-store type instruction. I
want to generate some instructions for register indirect mode, like
following:
IR:
@a = local_unnamed_addr global i32 0, align 4
@b = local_unnamed_addr global i32 0, align 4
@c = local_unnamed_addr global i32 0, align 4
; Function Attrs: norecurse nounwind
define void @foo() {
entry:
%0 = load i32, i32* @a, align 4
%1 = load i32, i32* @b, align 4
%add = add nsw i32 %1, %0
store i32 %add, i32*...

Why is there still ineffective code after -o3 optimization?
...uments where one
is a reference.
Therefore, I expect every instruction not altering the value at the 2nd
arguments address should be ineffective.
Here is the function definition (see below for full ll):
define void @_Z27entityMainDataInputCallbackdRd(double %input, double*
dereferenceable(8) %o0) local_unnamed_addr #0 {
The ll below has been optimized using opt -O3 -S input.ll -o out.ll
The cfg is plotted as png here:
https://ibb.co/f1B0rnm
My question is: why is there still some unnecessary 'lint' in the
optimization result?
E.G. from the splittedblock19 onwards:
there is one effective instruction...
