+// Version 1.10

+// Jan 23rd, 2000

+// Version 1.00

+// May 20th, 1999

+// Todd C. Wilson, Fresh Ground Software

+// (todd@nopcode.com)

+// This header file will kick in settings for Visual C++ 5 and 6 that will (usually)

+// result in smaller exe's.

+// The "trick" is to tell the compiler to not pad out the function calls; this is done

+// by not using the /O1 or /O2 option - if you do, you implicitly use /Gy, which pads

+// out each and every function call. In one single 500k dll, I managed to cut out 120k

+// by this alone!

+// The other two "tricks" are telling the Linker to merge all data-type segments together

+// in the exe file. The relocation, read-only (constants) data, and code section (.text)

+// sections can almost always be merged. Each section merged can save 4k in exe space,

+// since each section is padded out to 4k chunks. This is very noticable with smaller

+// exes, since you could have only 700 bytes of data, 300 bytes of code, 94 bytes of

+// strings - padded out, this could be 12k of runtime, for 1094 bytes of stuff!

+// Note that if you're using MFC static or some other 3rd party libs, you may get poor

+// results with merging the readonly (.rdata) section - the exe may grow larger.

+// To use this feature, define _MERGE_DATA_ in your project or before this header is used.

+// With Visual C++ 5, the program uses a file alignement of 512 bytes, which results

+// in a small exe. Under VC6, the program instead uses 4k, which is the same as the

+// section size. The reason (from what I understand) is that 4k is the chunk size of

+// the virtual memory manager, and that WinAlign (an end-user tuning tool for Win98)

+// will re-align the programs on this boundary. The problem with this is that all of

+// Microsoft's system exes and dlls are not tuned like this, and using 4k causes serious

+// exe bloat. Very noticable for smaller programs.

+// The "trick" for this is to use the undocumented FILEALIGN linker parm to change the

+// padding from 4k to 1/2k, which results in a much smaller exe - anywhere from 20%-75%

+// depending on the size. 

+

+

+#ifdef NDEBUG

+// /Og (global optimizations), /Os (favor small code), /Oy (no frame pointers)

+#pragma optimize("gsy",on)

+

+// Note that merging the .rdata section will result in LARGER exe's if you using

+// MFC (esp. static link). If this is desirable, define _MERGE_RDATA_ in your project.

+#pragma comment(linker,"/merge:.rdata=.data")

+#if _MSC_VER >= 1000

+// Only supported/needed with VC6; VC5 already does 0x200 for release builds.

+// Totally undocumented! And if you set it lower than 512 bytes, the program crashes.

+// Either leave at 0x200 or 0x1000

+#pragma comment(linker,"/FILEALIGN:0x200")
