As an experiment for CompactSysUtils project I started a while ago, I have used this opportunity to demonstrate why FPC should reorganize the FPC sysutils unit for better smartlinking (i.e. create just one more unit than just sysutils to take care of smartlinking).
Many functions in the FPC sysutils unit do not rely on any finalization or initialization code. By simple copy and pasting some of the sysutils functions into a unit of my own, called CompactSysUtils, I have gotten the DLL down to 40KB which was previously 91KB Project files showing 40KB DLL versus 91KB DLL is here: http://z505.com/pascal/MD5Hash/MD5Hash_COMPARE.zip CompactUtils and CompactSysUtils project is here: https://opensvn.csie.org/pspcgi/psp-lib-1.5.0-devel/src/extras/CompactUtils/ In order to compile the CompactUtils version in that zip file, you will need the latest copy of the compactutils.pas and compactsysutils.pas which is located on the SVN link above. Sometimes we don't worry so much about bloat like this since "today's processors are getting faster", but this one is a no brainer. There is no work to be done other than copy/paste functions and reorganize them such as I have done with CompactSysUtils project. I have also made notes about this before on the mailing lists, such as mentioning how the findpart function can be cut copied and pasted right out of the StrUtils unit so that no sysutils initialization and finalization is hauled in. Maybe people can learn from this with the lazarus project too - as I'm guessing some (not all) the reason lazarus exe's are so big is because or simple initialization/finalization bloat. Sure there are abstraction bloat that is incurred for multi-platform programming in SOME CASES, but I've just proved with above CompactUtils project that abstraction has nothing to do with the majority of the bloat in this case. Rather simple reorganization in this case, to cut the EXE and DLL in half (actually, *more* than half). So either I continue to maintain this compactutils project with my elite cutting/copying/pasting skills or the FPC team decides to reorganize sysutils at the distribution level (i.e. kill the compactutils project and just do it in the RTL itself). Also anyone wishing to participate in this compactutils project I started is welcome - I started it to gain smartlinking knowledge myself and I'm sure others could benefit from knowing more about smartlinking. _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
