Hi,
I wrote 2 simple programs to compare the size of the Javascript files
generated in unoptimized mode for both array and vector:
1. Array version:
int main()
{
int arr1[2000];
add(arr1);
return 0;
}
void add(int arr[])
{
for(int i=0;i<2000;i++)
{
arr[i]=i;
}
}
2. Vector version:
int main()
{
vector<int> v1;
add(v1);
return 0;
}
void add(vector<int>& v)
{
for(int i=0;i<2000;i++)
{
v.push_back(i);
}
}
I was quite surprised that the size of the JS file generated for the array
is only 203KB but the vector version took up 2393KB. Are there built-in
optimizations for STL classes in Emscripten that I could leverage on to
shrink the file size or do I have to implement my own vector classes? Any
suggestions would be much appreciated. Thanks in advance.
