Reduce memory usage for the runtime with generics code. #16

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 

1. Estimated Time

Few hours of coding and one day or two of testing

2. Description of the project

Cache unbound generic open parameter memory usage on the runtime.
On some spots while decoding generic types we need to use type parameters
that are not bound to a specific file. Currently mono always allocate from
the image memory pool when using them, it's not a lot but we could do better.

The idea is to stop allocating all the time and just cache for small index
generic parameters. This should reduce image mempool usage a bit, but a
good to have.

It would be good to get some numbers on saving with at least some decently
sized generics code.

3. Links that will be useful to a student.

The function than needs to be changed is
metadata.c/mono_metadata_parse_generic_param
