Hi John
Perhaps we should give this function another name.
function CharPosRev_JOH_IA32_4_a(SearchChar : Char; const S: string) :
pshuflw xmm0, xmm0, 0
pshufd xmm0, xmm0, 0 {All 16 Bytes of xmm0 = cl}
movdqu xmm1, [eax+edx] {Check Last 16 Chars}
pcmpeqb xmm1, xmm0
pmovmskb ecx, xmm1
What about?
function CharPosRev_JOH_SSE2_1_a(SearchChar : Char; const S: string) :
Best regards
Dennis Kjaer Christensen
