Optimizing a bubble sort implementation in C for an x86-64 architecture
I've examined the assembly output for both -O2 and -O3 versions. While -O3 seems to attempt vector instructions like movdqa, there might be other factors affecting performance, like unnecessary register spills or missed opportunities for further vectorization.
Could additional instructions introduced by -O3 outweigh the benefit of vectorization for bubble sort on x86-64? Are there any compiler flags or optimization techniques specific to x86-64 that might be more suitable for this scenario, considering the limitations of bubble sort for large datasets?
