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.

[0] in and out are defined by the API of this function to be 16-byte
aligned, so the cast from a void * to a struct aligned * is guaranteed
to be okay.
