◆ isPTruePromoted()
Checks if a ptrue intrinsic call is promoted.
The act of promoting a ptrue will introduce zeroing. For example:
%1 = <vscale x 4 x i1> call @llvm.aarch64.sve.ptrue.nxv4i1(i32 31) %2 = <vscale x 16 x i1> call @llvm.aarch64.sve.convert.to.svbool.nxv4i1(<vscale x 4 x i1> %1) %3 = <vscale x 8 x i1> call @llvm.aarch64.sve.convert.from.svbool.nxv8i1(<vscale x 16 x i1> %2)
%1 is promoted, because it is converted:
<vscale x 4 x i1> => <vscale x 16 x i1> => <vscale x 8 x i1>
via a sequence of the SVE reinterpret intrinsics convert.{to,from}.svbool.
