Package: gcc-4.5 Version: 4.5.2-6 Severity: wishlist Attached is a file, ofb.c. When compiling with -DVECTOR_T, the xor and copy operation is appropriately vectorized using SSE and SSE2 instructions (these are assumed, since the machine is amd64). Without -DVECTOR_T, the operation is not vectorized and is instead replaced by 16 movzbl-xorb-movb operations. In the original code, vectorization causes not only a code size decrease, but also a significant speed increase (87 MiB/s to 96 MiB/s). It's unclear to me why GCC isn't vectorizing this operation. All of in, out, and c->buf are guaranteed to be 16-byte aligned[0]. GCC even recognizes this when using VECTOR_T because it uses movdqa instead of the unaligned movdqu. I don't think I should have to rewrite the code to use vector types when the operation is clearly trivially vectorizable. I want GCC to produce identical code for either case. I've tried with gcc 4.4, 4.5, 4.6, and snapshot, and all of them have this bug. The code is compiled as follows: gcc -fPIC -shared -std=c99 -O3 --save-temps -o ofb.so ofb.c or gcc -DVECTOR_T -fPIC -shared -std=c99 -O3 --save-temps -o ofb.so ofb.c as the case may be. The original C file is included, as are the two .i files and the two .s files. They are marked as either with -DVECTOR_T or without it. gcc -v output: Using built-in specs.
