Arnold Schwaighofer b6f4872d29 ARM cost model: Increase the cost for vector casts that use the stack ... Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend currently lowers those using stack accesses. This was responsible for a significant degradation on MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1 where we vectorize one loop to a vector factor of 16. After this patch we select a vector factor of 4 which will generate reasonable code. unsigned char cle[32]; void test(short c) { unsigned short compte; for (compte = 0; compte <= 31; compte++) { cle[compte] = cle[compte] ^ c; } } radar://13220512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176898 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-12 21:19:22 +00:00
