2017-06-23backend: refine load/store merging algorithmrander1-9/+78
Now it works for sequence: load(0), load(1), load(2) but it cant work for load(2), load(0), load(1). because it compared the last merged load and the new one not all the loads for sequence: load(0), load(1), load(2). the load(0) is the start, can find that load(1) is successor without space, so put it to a merge fifo. then the start is moving to the top of fifo load(1), and compared with load(2). Also load(2) can be merged for load(2), load(0), load(1). load(2) cant be merged with load(0) for a space between them. So skip load(0) and mov to next load(1).And this load(1) can be merged. But it never go back merge load(0) Now change the algorithm. (1) find all loads maybe merged arround the start by the distance to the start. the distance is depended on data type, for 32bit data, the distance is 4. Put them in a list (2) sort the list by the distance from the start. (3) search the continuous sequence including the start to merge V2: (1)refine the sort and compare algoritm. First find all the IO in small offset compared to start. Then call std:sort (2)check the number of candidate IO to be favorable to performance for most cases there is no chance to merge IO Signed-off-by: rander.wang <rander.wang@intel.com> Reviewed-by: Ruiling Song <ruiling.song@intel.com>
2017-06-23backend: add global immediate optimizationrander1-25/+342
there are some global immediates in global var list of LLVM. these imm can be integrated in instructions. for compiler_global_immediate_optimized test in utest, there are two global immediates: L0: MOV(1) %42<0>:UD : 0x0:UD MOV(1) %43<0>:UD : 0x30:UD used by: ADD(16) %49<1>:D : %42<0,1,0>:D %48<8,8,1>:D ADD(16) %54<1>:D : %43<0,1,0>:D %53<8,8,1>:D it can be ADD(16) %49<1>:D : %48<8,8,1>:D 0x0:UD ADD(16) %54<1>:D : %53<8,8,1>:D 0x30:UD Then the MOV can be removed. And after this optimization, ADD 0 can be change to MOV, then local copy propagation can be done. V2: (1) add environment variable to enable/disable the optimization (2) refine the architecture of imm optimization, inherit from global optimizer not local block optimizer V3: merge with latest master driver V4: (1)refine some type errors (2)remove UD/D check for no need (3)refine imm calculate for UD/D Signed-off-by: rander.wang <rander.wang@intel.com> Reviewed-by: Ruiling Song <ruiling.song@intel.com>
2017-06-23GBE: clean llvm module's clone and release.Yang, Rong R10-58/+76
There are some changes: 1. Clone the module before call LLVMLinkModules2, remove other clones for it. 2. Don't delete module in function llvmToGen. 3. Add a function programNewFromLLVMFile so genProgramNewFromLLVM and buildFromLLVMModule only handle llvm module. Actually, programNewFromLLVMFile is only used by clCreateProgramWithLLVMIntel, and I think it is useless, maybe we could delete it at all. V2: define errDiag beside #if/#endif.

2017-05-25Fix bug of clEnqueueCopyBufferToImage and clEnqueueCopyImageToBuffer.Yan Wang5-28/+89
"imagedim_non_pow_2" cases of basic modudle of confrmance shows regression after use TILE_Y mode for large image by previous patch. This bug comes from the non-align16 kernel of clEnqueueCopyBufferToImage and clEnqueueCopyImageToBuffer. It will force CL_RGBA/CL_UNORM_INT8/8191x8192 image of conformance test to CL_R/CL_UNSIGNED_INT8/32764x8192 image for copying. So it makes width as 8191 x 4 = 32764 and its width will exceed the maximum width (16 x 1024 = 16384) of GEN surface state structure which only has 14 bits. So use align4 copy kernel to avoid this bug. Signed-off-by: Yan Wang <yan.wang@linux.intel.com>
