In ASPSOldGen the 0N/A// maximum size of the generation can change as the boundary 0N/A// moves. The "maximum size of the generation" is still a valid 0N/A// concept since the generation can grow and shrink within that 0N/A// maximum. There are lots of useful checks that use that 0N/A// maximum. In PSOldGen the method max_gen_size() returns 0N/A// _max_gen_size (as set by the PSOldGen constructor). This 0N/A// is how it always worked. In ASPSOldGen max_gen_size() 0N/A// returned the size of the reserved space for the generation. 0N/A// That can change as the boundary moves. Below the limit of 0N/A// the size of the generation is passed to the PSOldGen constructor 0N/A// for "_max_gen_size" (have to pass something) but it is not used later. 0N/A // If the used or minimum gen size (aligned up) is greater 0N/A // than the total reserved size, then the space available 0N/A // for contraction should (after proper alignment) be 0 0N/A // Use the "increment" fraction instead of the "decrement" fraction 0N/A // to allow the other gen to expand more aggressively. The 0N/A // "decrement" fraction is conservative because its intent is to 0N/A // only reduce the footprint. 0N/A // Also adjust for inter-generational alignment
