The emulation code for the pdist instruction uses > RS1(insn) for both source registers rs1 and rs2, which is obviously > wrong and leads to the instruction doing nothing (the observed > problem), and further inspection of the code shows that RS1 uses a > shift of 24 and RD a shift of 25, which clearly cannot both be right; > examining SPARC documentation indicates the correct shift for RS1 is > 14. > > This patch fixes the bug if single-stepping over the affected > instruction in the debugger, but not if the testcase is run > standalone. For that, Wind River has another patch I hope they will > send as a followup to this patch submission. > > Signed-off-by: Joseph Myers <joseph@xxxxxxxxxxxxxxxx> Patch applied, thanks! -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
