Potential Problems in Using Global Register Coloring

Gurudeep Singh

Dear All,

I'm thinking about using global register coloring option but can't be sure of
what potential problems might come up after implementing it.

I'm using C251 compiler for SLE70 family.

I've heard that global register coloring causes problems with following area.

1. Function pointers
2. Interrupts

If you have ever experienced such problems or any other problem regarding Global Register Coloring please share your experiences.
