2017-05-02DRTVWR-418, MAINT-6996: Rationalize LLMemory wrt 64-bit support.Nat Goodspeed
There were two distinct LLMemory methods getCurrentRSS() and getWorkingSetSize(). It was pointless to have both: on Windows they were completely redundant; on other platforms getWorkingSetSize() always returned 0. (Amusingly, though the Windows implementations both made exactly the same GetProcessMemoryInfo() call and used exactly the same logic, the code was different in the two -- as though the second was implemented without awareness of the first, even though they were adjacent in the source file.) One of the actual MAINT-6996 problems was due to the fact that getWorkingSetSize() returned U32, where getCurrentRSS() returns U64. In other words, getWorkingSetSize() was both useless *and* wrong. Remove it, and change its one call to getCurrentRSS() instead. The other culprit was that in several places, the 64-bit WorkingSetSize returned by the Windows GetProcessMemoryInfo() call (and by getCurrentRSS()) was explicitly cast to a 32-bit data type. That works only when explicitly or implicitly (using LLUnits type conversion) scaling the value to kilobytes or megabytes. When the size in bytes is desired, use 64-bit types instead. In addition to the symptoms, LLMemory was overdue for a bit of cleanup. There was a 16K block of memory called reserveMem, the comment on which read: "reserve 16K for out of memory error handling." Yet *nothing* was ever done with that block! If it were going to be useful, one would think someone would at some point explicitly free the block. In fact there was a method freeReserve(), apparently for just that purpose -- which was never called. As things stood, reserveMem served only to *prevent* the viewer from ever using that chunk of memory. Remove reserveMem and the unused freeReserve(). The only function of initClass() and cleanupClass() was to allocate and free reserveMem. Remove initClass(), cleanupClass() and the LLCommon calls to them. In a similar vein, there was an LLMemoryInfo::getPhysicalMemoryClamped() method that returned U32Bytes. Its job was simply to return a size in bytes that could fit into a U32 data type, returning U32_MAX if the 64-bit value exceeded 4GB. Eliminate that; change all its calls to getPhysicalMemoryKB() (which getPhysicalMemoryClamped() used internally anyway). We no longer care about any platform that cannot handle 64-bit data types.
2016-11-22DRTVWR-418: Use uintptr_t when casting pointers to ints.Nat Goodspeed
LLPrivateMemoryPool and LLPrivateMemoryPoolManager have assumed that it's always valid to cast a pointer to U32. With 64-bit pointers, no longer true.
