When building with clang, we get:
error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]
This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror. All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.
This is equivalent to this commit in gdb:
3e019bdc20eb81b91ab5bc774386201b874c0bac
gdb: Use -Werror when checking for (un)supported warning flags
We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.
= OVERVIEW = The Synacor Challenge is a fun programming exercise with a number of puzzles built into it. You can find more details about it here: https://challenge.synacor.com/ The first puzzle is writing an interpreter for their custom ISA. This is a simulator for that custom CPU. The CPU is quite basic: it's 16-bit with only 8 registers and a limited set of instructions. This means the port will never grow new features. See README.arch-spec for more details. Implementing it here ends up being quite useful: it acts as a simple constrained "real world" example for people who want to implement a new simulator for their own architecture. We demonstrate all the basic fundamentals (registers, memory, branches, and tracing) that all ports should have.
