C11 Generics

A simple implementation of type generic bounds-checked arrays in C, using the C11 _Generic keyword and XX list macros.

Compile with a C11-compliant compiler providing _Generic keyword support using:
cc -std=c11 -O3 chkd_array_demo.c -o chkd_array_demo

Annotate and view the output of the included performance profiles using:
callgrind_annotate callgrind.out.xxxxx
cachegrind_annotate cachegrind.out.xxxxx

Run your own performance profiles (assuming you have Valgrind) using:
valgrind --dsymutil=yes --tool=callgrind ./chkd_array_demo 50000000 50000 500
valgrind --dsymutil=yes --tool=cachegrind --branch-sim=yes ./chkd_array_demo 50000000 50000 500
(Tweak the last 3 numbers on both command lines to vary the test params.)

My system architecture:
