8059758: Footprint regressions with JDK-8038423
Summary: Changes in JDK-8038423 always initialize (zero out) virtual memory used for auxiliary data structures. This causes a footprint regression for G1 in startup benchmarks. This is because they do not touch that memory at all, so the operating system does not actually commit these pages. The fix is to, if the initialization value of the data structures matches the default value of just committed memory (=0), do not do anything.

| 96 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in | |
| 97 // system header files. On 32-bit architectures, there is no problem. | |
| 98 // On 64-bit architectures, defining NULL as a 32-bit constant can cause | |
| 99 // problems with varargs functions: C++ integral promotion rules say for | |
| 100 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a | |
| 101 // varargs function it will remain 32-bits. Depending on the calling | |
| 102 // convention of the machine, if the argument is passed on the stack then | |
| 103 // only 32-bits of the "NULL" pointer may be initialized to zero. The | |
| 104 // other 32-bits will be garbage. If the varargs function is expecting a | |
| 105 // pointer when it extracts the argument, then we have a problem. | |
| 106 // | |
| 107 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0. | |
| 108 // | |
| 109 // Note: this fix doesn't work well on Linux because NULL will be overwritten | |
