[InstCombine] Generate better code for std::bit_floor from libstdc++
Without this patch, std::bit_floor<uint32_t> in libstdc++ is compiled
as:
%eq0 = icmp eq i32 %x, 0
%lshr = lshr i32 %x, 1
[InstCombine] Generate better code for std::bit_floor from libstdc++
Without this patch, std::bit_floor<uint32_t> in libstdc++ is compiled
as:
%eq0 = icmp eq i32 %x, 0
%lshr = lshr i32 %x, 1
%ctlz = tail call i32 @llvm.ctlz.i32(i32 %lshr, i1 false)
%sub = sub i32 32, %ctlz
%shl = shl i32 1, %sub
%sel = select i1 %eq0, i32 0, i32 %shl
With this patch:
%eq0 = icmp eq i32 %x, 0
%ctlz = call i32 @llvm.ctlz.i32(i32 %x, i1 false)
%lshr = lshr i32 -2147483648, %1
%sel = select i1 %eq0, i32 0, i32 %lshr
This patch recognizes the specific pattern emitted for std::bit_floor
in libstdc++.
