Re: [pcre-dev] Adding SSE2 support to PCRE2-JIT
May have a question about pcre executable portability? Not all x86 machines support SSE2. Is it there a run-time check for SSE2 support with a fall-back code, or is it a compile time option? The SSE2 code path is optional. It is checked at runtime using CPUID instruction on x86-32 (it is always available on x86-64 bit).
