…#102133) This generalizes the indir reordering optimization (that currently only triggers for loads) to kick in for GT_STOREIND nodes. The main complication with doing this is the fact that the data node of the second indirection needs its own reordering with the previous indirection. The existing logic works by reordering all nodes between the first and second indirection that are unrelated to the second indirection's computation to happen after it. Once that is done we know that there are no uses of the first indirection's result between it and the second indirection, so after doing the necessary interference checks we can safely move the previous indirection to happen after the data node of the second indirection. Example: ```csharp class Body { public double x, y, z, vx, vy, vz, mass; } static void Advance(double dt, Body[] bodies) { foreach (Body b in bodies) { b.x += dt * b.vx; b.y += dt * b.vy; b.z += dt * b.vz; } } ``` Diff: ```diff @@ -1,18 +1,17 @@ -G_M55007_IG04: ;; offset=0x001C +G_M55007_IG04: ;; offset=0x0020 ldr x3, [x0, w1, UXTW #3] ldp d16, d17, [x3, #0x08] ldp d18, d19, [x3, #0x20] fmul d18, d0, d18 fadd d16, d16, d18 - str d16, [x3, #0x08] - fmul d16, d0, d19 - fadd d16, d17, d16 - str d16, [x3, #0x10] + fmul d18, d0, d19 + fadd d17, d17, d18 + stp d16, d17, [x3, #0x08] ldr d16, [x3, #0x18] ldr d17, [x3, #0x30] fmul d17, d0, d17 fadd d16, d16, d17 str d16, [x3, #0x18] add w1, w1, #1 cmp w2, w1 bgt G_M55007_IG04 ```
