Currently we do something like this : ssa_0 = ... ssa_1 = ... * spill ssa_0, ssa_1 call1() * fill ssa_0, ssa_1 ssa_2 = ... ssa_3 = ... * spill ssa_0, ssa_1, ssa_2, ssa_3 call2() * fill ssa_0, ssa_1, ssa_2, ssa_3 If we assign the same possition to ssa_0 & ssa_1 in the spilling stack, then on call2(), we know that those values are already present in memory at the right location and we can avoid respilling them. The result would be something like this : ssa_0 = ... ssa_1 = ... * spill ssa_0, ssa_1 call1() * fill ssa_0, ssa_1 ssa_2 = ... ssa_3 = ... * spill ssa_2, ssa_3 call2() * fill ssa_0, ssa_1, ssa_2, ssa_3 Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Konstantin Seurer <konstantin.seurer@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/16556>
