# The cost of C++ exceptions
This is the code for my medium article
# Building
You will need `meson` on Linux.
## `gcc`
```shell
meson setup gcc
meson compile -v -C gcc
```
## `clang`
You must install `clang`.
```shell
CC=clang CXX=clang++ CFLAGS=-funroll-loops CXXFLAGS=-funroll-loops meson setup clang
meson compile -v -C clang
```
## Intel OneAPI
A very good compiler that few people use because it is not the default one on any OS. Available for Linux in a Debian/Ubuntu and RedHat style-repositories. Uses the `g++` runtime and library. Replace `12` with your `g++` version.
```shell
CC=/opt/intel/oneapi/compiler/latest/linux/bin/icx \
CXX=/opt/intel/oneapi/compiler/latest/linux/bin/icpx \
CFLAGS=--gcc-install-dir=/usr/lib/gcc/x86_64-linux-gnu/12 \
CXXFLAGS=--gcc-install-dir=/usr/lib/gcc/x86_64-linux-gnu/12 \
meson setup oneapi
meson compile -v -C oneapi
```
# Run
```shell
cd {gcc|clang|oneapi}
bash ../run.sh
```
