| 8 | This script allows to run a benchmark on a set of different compilers/compiler options.
|
|---|
| 9 | It takes two arguments:
|
|---|
| 10 | - a file defining the list of the compilers with their options
|
|---|
| 11 | - the .cpp file of the benchmark
|
|---|
| 12 |
|

| 13 | Examples:
|
|---|
| 14 |
|
|---|
| 15 | $ ./bench_multi_compilers.sh basicbench.cxxlist basicbenchmark.cpp
