[x86] Implement a faster vector population count based on the PSHUFB in-register LUT technique. Summary: A description of this technique can be found here: http://wm.ite.pl/articles/sse-popcount.html The core of the idea is to use an in-register lookup table and the PSHUFB instruction to compute the population count for the low and high nibbles of each byte, and then to use horizontal sums to aggregate these into vector population counts with wider element types. On x86 there is an instruction that will directly compute the horizontal sum for the low 8 and high 8 bytes, giving vNi64 popcount very easily. Various tricks are used to get vNi32 and vNi16 from the vNi8 that the LUT computes. The base implemantion of this, and most of the work, was done by Bruno in a follow up to D6531. See Bruno's detailed post there for lots of timing information about these changes. I have extended Bruno's patch in the following ways: 0) I committed the new tests with baseline sequences so this shows a diff, and regenerated the tests using the update scripts. 1) Bruno had noticed and mentioned in IRC a redundant mask that I removed. 2) I introduced a particular optimization for the i32 vector cases where we use PSHL + PSADBW to compute the the low i32 popcounts, and PSHUFD + PSADBW to compute doubled high i32 popcounts. This takes advantage of the fact that to line up the high i32 popcounts we have to shift them anyways, and we can shift them by one fewer bit to effectively divide the count by two. While the PSHUFD based horizontal add is no faster, it doesn't require registers or load traffic the way a mask would, and provides more ILP as it happens on different ports with high throughput. 3) I did some code cleanups throughout to simplify the implementation logic. 4) I refactored it to continue to use the parallel bitmath lowering when SSSE3 is not available to preserve the performance of that version on SSE2 targets where it is still much better than scalarizing as we'll still do a bitmath implementation of popcount even in scalar code there. With #1 and #2 above, I analyzed the result in IACA for sandybridge, ivybridge, and haswell. In every case I measured, the throughput is the same or better using the LUT lowering, even v2i64 and v4i64, and even compared with using the native popcnt instruction! The latency of the LUT lowering is often higher than the latency of the scalarized popcnt instruction sequence, but I think those latency measurements are deeply misleading. Keeping the operation fully in the vector unit and having many chances for increased throughput seems much more likely to win. With this, we can lower every integer vector popcount implementation using the LUT strategy if we have SSSE3 or better (and thus have PSHUFB). I've updated the operation lowering to reflect this. This also fixes an issue where we were scalarizing horribly some AVX lowerings. Finally, there are some remaining cleanups. There is duplication between the two techniques in how they perform the horizontal sum once the byte population count is computed. I'm going to factor and merge those two in a separate follow-up commit. Differential Revision: http://reviews.llvm.org/D10084 llvm-svn: 238636

[x86] Fix a pretty horrible bug and inconsistency in the x86 asm parsing (and latent bug in the instruction definitions). This is effectively a revert of r136287 which tried to address a specific and narrow case of immediate operands failing to be accepted by x86 instructions with a pretty heavy hammer: it introduced a new kind of operand that behaved differently. All of that is removed with this commit, but the test cases are both preserved and enhanced. The core problem that r136287 and this commit are trying to handle is that gas accepts both of the following instructions: insertps $192, %xmm0, %xmm1 insertps $-64, %xmm0, %xmm1 These will encode to the same byte sequence, with the immediate occupying an 8-bit entry. The first form was fixed by r136287 but that broke the prior handling of the second form! =[ Ironically, we would still emit the second form in some cases and then be unable to re-assemble the output. The reason why the first instruction failed to be handled is because prior to r136287 the operands ere marked 'i32i8imm' which forces them to be sign-extenable. Clearly, that won't work for 192 in a single byte. However, making thim zero-extended or "unsigned" doesn't really address the core issue either because it breaks negative immediates. The correct fix is to make these operands 'i8imm' reflecting that they can be either signed or unsigned but must be 8-bit immediates. This patch backs out r136287 and then changes those places as well as some others to use 'i8imm' rather than one of the extended variants. Naturally, this broke something else. The custom DAG nodes had to be updated to have a much more accurate type constraint of an i8 node, and a bunch of Pat immediates needed to be specified as i8 values. The fallout didn't end there though. We also then ceased to be able to match the instruction-specific intrinsics to the instructions so modified. Digging, this is because they too used i32 rather than i8 in their signature. So I've also switched those intrinsics to i8 arguments in line with the instructions. In order to make the intrinsic adjustments of course, I also had to add auto upgrading for the intrinsics. I suspect that the intrinsic argument types may have led everything down this rabbit hole. Pretty happy with the result. llvm-svn: 217310

This patch backs out r136287 and then changes those places as well as some others to use 'i8imm' rather than one of the extended variants. Naturally, this broke something else. The custom DAG nodes had to be updated to have a much more accurate type constraint of an i8 node, and a bunch of Pat immediates needed to be specified as i8 values. The fallout didn't end there though. We also then ceased to be able to match the instruction-specific intrinsics to the instructions so modified. Digging, this is because they too used i32 rather than i8 in their signature. So I've also switched those intrinsics to i8 arguments in line with the instructions. In order to make the intrinsic adjustments of course, I also had to add auto upgrading for the intrinsics. I suspect that the intrinsic argument types may have led everything down this rabbit hole. Pretty happy with the result. llvm-svn: 217310
