No, that is not the case. But llvm-based fpc 3.3.1 is only marginally
faster than plain fpc 3.3.1 on integer calculations and not much faster
(perhaps around 20%) on floating point
Re-hello Sieghard.
Thanks for the results.
And... hum...
fpc 3.3.1 does better than fpc-llvm 3.3.1...
So fpc 3.3.1 is very good
or fpc-llvm 3.3.1 dont use yet all the power of llvm
or llvm is a joke.

You made me curious, and as I had meant to attempt to experiment with

those benchmarks
those benchmarks are not fair , c++ uses simd intrinsics and openmp
for multithreading , so in multicore cpu its much faster than fpc .
maybe the speed becomes equal if they uses only native language
without addons
