This question probably has a one-liner answer, but I haven't had any luck with google regarding how gcc optimizes regarding virtual method invocations. Assuming I have multiple .cpp files, and I ...

Figure 2: Geomean of 50 use cases normalized to baseline (GCC 9.4 with default optimization flags) The impact of the compiler and flags was much more pronounced in some use cases (see figure 3).

On another forum a person put forward the assertion that GCC has caught up to Intel C/C++ compiler for vectorization and that Intel is even pushing their optimizations into GCC. Is this true? I'm ...

The entire realm of open-source software could get a performance boost if all goes well with a plan to overhaul a crucial programming tool called GCC. Almost all open-source software is built with ...

Thus GCC performance in that case is very important.GCC 5.0 should give significant performance gain (up to 30%) for applications with hot integer loops like cryptography, data protection, data Part2.
