So in terms of looking at some of the code, I'm wondering something. What is generally best to try for something generic that you want to work in every environment you work on (i.e. portability concerns)? I guess I'm asking "How does one select which routine(s) you want to try out?" Another side question: If I wanted to try to contribute some input (there are a couple of the categories I saw on the list that I've had some extensive testing myself for the project above), how would I do that? Just posting here? I'm not interested in a "contest" or anything like that, just looking for intellectual enlightenment and contribution, more or less. Hopefully I can be of some help somewhere.

If you select the RTL Replacement winners you will be safe ;-) but at the moment the fastcode have a small problem the library is in a bad state. Try to look at the Direct Calling Libraries http://fastcode.sourceforge.net/fastcodeproject/55.htm Quote: Another side question: If I wanted to try to contribute some input (there are a couple of the categories I saw on the list that I've had some extensive testing myself for the project above), how would I do that?

Not sure i understand you ... But if you have some test/validation we miss in some of the fastcode B&V please post them here :-) Regards Lars G Back to top A Programmer Guest Posted: Sat Oct 29, 2005 4:38 pm    Post subject: Re: Performance Bottlenecks It depends on whether I can make them work with Delphi 3 or not. Most of the stuff I've encountered won't compile for various reasons (but can be made to compile if the code doesn't use anything D3 supports). I meant that I've done a lot of testing on sorts (R&D for various projects of mine) and could maybe offer some insights on both code and testing aspects. It looks like it's something that people are trying to hammer out right now, so perhaps I can try to offer some input if I have something relevant to say.

Maybe you can get some help from the D5Support.pas I wrote, that is used at least in the IntToStr B&V. In that file I've collected defines and declarations of some of the things that are missing in D5. I suspect that the same things are missing in D3 :-) Maybe we should rename that file to 'LegacySupport.pas' and add D3 specific defines and declarations too when we find them? As for the contest/library functions you will have problems with many of the assembler functions (later versions of Delphi add a lot of mnemonics which are not availabel in our old beasts), plain Pascal versions should not be impossible to get working under D3. -- Anders Isaksson, Sweden BlockCAD: http://web.telia.com/~u16122508/proglego.htm Gallery: http://web.telia.com/~u16122508/gallery/index.htm Back to top A Programmer Guest Posted: Sun Oct 30, 2005 1:24 am    Post subject: Re: Performance Bottlenecks It will help. The major problem though to get around for D3 is that there's no such critter as Int64. D3 is still very Borland Pascal legacy in that way. D3 does support DWord, but you need the Windows unit for that to happen (at a huge cost of memory and exec size). I can always post lists of compiler errors if people are interested in a "legacy D3" support.

If you are interested, I can most definitely post any and all compiler messages for whatever it is if people are willing to look into it: In the meantime, I tried to compile FastMM446 with the Delphi 3 command-line compiler (so I could capture the messages).

But like I mentioned, I was able to figure out what to change to get FastMM3 to compile. Anyway, here you go, if someone is willing to see what can be changed in the D5Support.Pas that can help compile this (and other things).

Anyway, here you go, if someone is willing to see what can be changed in the D5Support.Pas that can help compile this (and other things). Would Delphi 3 support really be realistic? And would it really help people? I think differences between D3 and D5 are much larger than between D5 and D7. Delphi 3 lacked many language features (IIRC for example dynamic arrays). These cannot be fixed by just including a unit. We held a poll here before to which 51 people replied (probably BASM and non-tech readers). Delphi 5 support turned out to be useful because as many as 23 people were still actively using D5 (more than D2005!). There were only 4 active D3 users, and these were probably only maintaining old apps. -- The Fastcode Project: http://www.fastcodeproject.org/ Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> Delphi Language BASM All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
