Re: [Mono-dev] misc: C# request info
Hi, well, I was looking into C# some, and admittedly I have much less fammiliarity with the language than with others... (I have started looking at ECMA-334 some, but it is long and a little awkward to answer specific questions from absent some digging...). so, firstly, it is my guess that in order to compile C# properly, it is required to load a whole group of files at once (I am uncertain whether the term 'assembly' also applies to the collection of input source files, or only to a produced DLL or EXE). You can load C# source code files as well as assemblies or modules. my guess is that it works like this: the group of files is loaded; each file is preprocessed and parsed (it is looking like C# uses a context-independent syntax?...); Incorrect, C# uses context dependent keywords. all of the namespaces and declarations are lifted out of the parse trees; each file's parse tree can then be compiled. from what I can tell, types are like this: type = qualifiers* type-name so, I can type: static Foo bar; and the parser will know that 'Foo' is the type, even if the type for Foo is not visible at the time of parsing (in C, this can't be done since there is no clear distinction or ordering between types and qualifiers, and so one would not know if 'Foo' is the type, or an intended variable name with the type being assumed to be 'int'). No, parser does not yet know the type of 'Foo'. so, in C we can have: unsigned int i; int unsigned i; int volatile i; _Complex float f; double _Complex g; unsigned i; short int j; int long k; .. so, my guess then is that C# code is just parsed, with no need to lookup, for example, is Foo a struct or class or other typedef'ed type? ... as far as the parser is concerned 'int' or 'byte' is syntactically not different from 'Foo' or 'Bar'?... Correct. Marek ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
Re: [Mono-dev] Mono.SIMD
Hey,
The big issue you're having is that you haven't implemented a SIMD algorithm
;) I spent 15 mins 'optimising' your code and came up with this. Notice that
I made everything a SIMD operation. There is no scalar code in the method
anymore. This tripled performance as compared to the non-SIMD version. On my
machine:
-FLOAT 00:00:00.3888930 Color
-SIMD 00:00:00.1266820 Mono.Simd.Vector4f
You'd want to double check the result just in case I made a mistake with my
alterations.

Re: [Mono-dev] Unable to call methods on managed objects while running Mono on the iPhone
Hi,
You have to compile your AOT code using --aot=full, and run the runtime using
the --full-aot option. When embedding, the later can be achieved by setting the
mono_aot_only variable to TRUE _before_ calling mono_jit_init ().

Re: [Mono-dev] Mono.SIMD
Hey,
The C++ code seems very similar to the C# SIMD code, so I don't know what
would make the C# version any faster. This question would be best directed
at jit guys, who may know what causes the difference.
If you want to try speeding up the mono version, you should just use trial
and error to see if you can rewrite things so that you can get better
performance. For example, unrolling the loop may improve performance
noticably.

Re: [Mono-dev] Developing using Mono/Gtk# Vs Mono.WinForms (Windows Linux)

The rule of thumb would use: if the majority of users are Windows, use WinForms. If Linux, use GTK#. Of course, this is assuming that you're equally skilled in both. Bear in mind that if one chooses Gtk# one will have to include it with one's Windows packages, as the vast majority of Windows users do not have it installed already. Winforms is available in both .Net and Mono as standard. The desktop integration of WinForms in Mono could be improved if someone does the work to allow use of native widgets. I suspect that this isn't possible, because native GTK+ widgets would require a GLib event loop, etc., and wouldn't be able to raise the SWF events that would be needed (which is why implementing SWF atop Gtk# was never a workable solution). The best that is likely possible is theming, which Mono has support for, but theming is a far cry from actual support (see also Word 6.0/Mac, one of the most hated Word releases of all time, which wasn't even themed but was hated by ~everyone because it didn't behave properly). On a related note, I would like to see a Qt backend for WinForms available as well. I believe the KDE project is still working on Qyoto. Mono's System.Windows.Forms doesn't have a backend that is handled by other toolkits (such as GTK+ or Qt), so this doesn't make sense. The entire SWF implementation is custom drawn with System.Drawing (itself built upon Cairo on Linux). In summary, Mono's SWF hasn't used native widgets in years, nor will it do so any time soon (afaik), and SWF looks like ass on Linux. Even if it didn't look like ass (and good theme engines will help), it will still behave differently from other Linux apps -- just see all the years of problems with the feel part of look and feel that Java Swing has dealt with (and oftentimes still suffers from). GTK+ on Windows has similar problems, from what I've heard (looking alien, not feeling correct, etc.). So there is no perfect, one framework fits all solution. (Just see all the people who claim to be able to tell a Qt app at a glance on OS X.) The best solution, from the user perspective, is to provide a UI for each platform, not provide one UI for all platforms. Unfortunately this increases costs, but users tend to prefer this solution, by far... - Jon ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
Re: [Mono-dev] Patch: Ternary ops in mini and general ATOMIC_CAS
Hi, My problems with this patch, and with adding support for ternary ops in general: - it increases the size of MonoInst by 4/8 bytes. - it slows down every phase of the JIT by changing linear code into loops, ie. instead of process sreg1 process sreg2 it is now a loop with an unknown upper bound. All this to add support for exactly one rarely used instruction, CAS.

Re: [Mono-dev] misc: C# request info
- Original Message - From: Marek Safar marek.sa...@seznam.cz To: BGB cr88...@hotmail.com Cc: mono-devel-list@lists.ximian.com Sent: Monday, February 23, 2009 7:56 PM Subject: Re: [Mono-dev] misc: C# request info Hi, well, I was looking into C# some, and admittedly I have much less fammiliarity with the language than with others... (I have started looking at ECMA-334 some, but it is long and a little awkward to answer specific questions from absent some digging...). so, firstly, it is my guess that in order to compile C# properly, it is required to load a whole group of files at once (I am uncertain whether the term 'assembly' also applies to the collection of input source files, or only to a produced DLL or EXE). You can load C# source code files as well as assemblies or modules. yes, ok. my guess is that it works like this: the group of files is loaded; each file is preprocessed and parsed (it is looking like C# uses a context-independent syntax?...); Incorrect, C# uses context dependent keywords. I meant, context independent as in, the parser can parse things without knowing about previous declarations. in C, it is necessary to know about declarations (typedefs, structs, ...) in order to be able to parse (otherwise... the syntax is ambiguous...). sadly, I am not all that familiar in detail with C#'s syntax. in C#, this would mean having to know about all of the classes in all of the visible namespaces before being able to parse, which would not seem to be the case. actually, it is looking to me (just my guess from looking at ECMA-334), that rather than processing code a few-tokens at a time and using a syntax where the current parsing depends on prior declarations, C# is using a syntax where it is possible to parse everything without knowing the types at parse-time (I will presume this is assumed/required from the way the language is structured), but that the syntax is not disambiguated be the next 1-or-2 tokens, but may require trying to parse everything that could work and using the first syntactic form that does work. this leads to a difference in parsing strategy, namely that rather than parsing along token-by-token and reporting a parse error the first time an unexpected token is seen, one descends into parsing branches, tries to parse, and if there would be a parse error then returning gracefully, allowing the next higher level to try the next possible interpretation. for example: '(Foo)' is ambiguous, and may be assumed to be a reference in parenthesis; '(Foo)bar' is recognized as a cast, on the grounds that otherwise it would not parse correctly. well, I am not strictly following the syntax structure given in the spec, mostly because to do so would require completely rewriting my existing parser, rather I am figuring out how to make it work (AFAICT, the descriptions in ECMA-334 are LR or LALR, but my parsers are typically hand-written recursive descent, and infact I am using a C parser as the basis for a C# parser, but am having to deal with many subtle but fundamental differences between the languages...). basically, one of the earlier forms of my C compiler is being used as a template (I am using an earlier form which uses S-Exps as the basis, rather than a later form which used DOM instead, as S-Exps are faster and less memory-consuming than DOM nodes). not all is free though, as I had to redirect (via search-and-replace) the old typesystem API to the new typesystem API. decided to leave out big chunk about my uncertainty over the convention of usage of letter-case in said APIs naming convention (which differs some from my newer naming rules, AKA: from 'alllower' to 'camelCase'). note: technically, I am doing all this for a few specific reasons: a new compiler frontend will be less effort for the time being than getting either my JBC or CIL frontend working (JBC and CIL still require some work...); the prior effort have already lead to me adding much of the needed machinery into the compiler core (I am still deciding on the details of how I will do exception handling, and am generally leaning against SEH, but there seems to be little standardization here, so I may do my own thing and possibly hook it into the others using VEH, ...); it would be much less effort (and ugliness) to modify a C frontend into a C# frontend, than to hack OO and namespaces onto C while still preserving its C-ness (I beat around some ideas, they were ugly...). as noted, this C# compiler would take the same basic compilation route as my existing C compiler (no intermediate CIL), and will use the same shared backend as my other compilers (since the backend and basic machinery are shared, it doesn't matter too much which frontend uses it, so no real lost effort here...). I have opted against adding CPS to my backend for now (creates too many issues, and would be too much effort, and for now generalized tail-calls and

Wine does not support .NET applications out of the box, but supposedly it does if you install the Windows version of Mono using Wine. Which is pointless except to test that scenario, since Mono runs natively on Linux. If Ubuntu supports it, you can try right-clicking the .exe file and choosing Run with Mono. If mono is not installed then you need to install mono-1.0-runtime and/or mono-2.0-runtime using the package manager, then try it again.

The problem here is that you are declaring new members with the same

No generics or obnoxious getter methods needed.
P.S. Names like REG_TYPE are in bad taste. Try something like RegistrationType.

I did not look too deeply into the exception you are getting because
this approach is simply wrong. You are copying the characters into a
new array that you never use again. In other words, this block of

work.
You probably want to look at the StringBuilder class as well. It
better encapsulates actions like this and is designed to prevent you

Re: [Mono-list] Generics Conversions
I'll explain this by jumping to Java for a moment. Java's arrays (but not
its generics) are broken in that they do what you want, which is broken:
Number[] numbers = new Double[1];
numbers[0] = 5;
This causes an ArrayStoreException at runtime. C#'s arrays and generics are
not broken in this manner, and will give a compile error instead.
A list of strings is not a list of objects, as long as a list is mutable.
C# 4 adds covariance and contravariance.
IEnumerableobject objects = new Liststring(); will be valid.
Listobject more = new Liststring(); will not be valid. List will still
be declared as ListT, and IEnumerable will be interface IEnumerableout T
{ stuff }.
Right now I'd use IEnumerableobject objects = stringList.Select(x =
(object)x); or if you must have List, Listobject objects =
stringList.Select(x = (object)x).ToList();
The advantage of the IEnumerable is that no actual copying is done.
Have fun,
Ricky.

This really stops me from using more Generics at the moment :-/ To further explain what the others have said, consider this C# code: Liststring stringList = new Liststring(); stringList.Add(a string); Listobject objectList = (Listobject) stringList; Console.WriteLine(objectList[0]); So far, so good, right? But what about: objectList.Add(10); Wait, that's a compile-time error, right? No, it's not. The signature of the Add method will be public void Listobject.Add(object item); and an integer can be boxed to satisfy this condition. This would add a non-string to a Liststring. The only type-safe way to prevent this from happening is to prevent a cast from Liststring to Listobject. As a side note, you should not use the (object as type) form of casting in this scenario -- use (type) object instead. The former will succeed regardless of the type of the object and return null, causing any usage of the result of the cast to throw a NullReferenceException. The latter will immediately throw a ClassCastException, which is a good indication of what is going on. Using the as cast would result in cryptic errors and time wasted debugging trying to figure out why the original object is null when in fact it's just not of the requested type. -- Chris Howie http://www.chrishowie.com http://en.wikipedia.org/wiki/User:Crazycomputers ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Well, futex does userspace locking, and it's possible that Mono uses

Just thought I'd throw that out there. Thanks for that suggestion. Unfortunately, it is a proprietary product (US$279/license), hence not compatible with my GPL'ed project. :-( I think I will have to actually provide different versions for .NET and Mono, and just use the different SQLite APIs then... Have you looked at DB4O? It's GPL, although it's not SQL ;) Andrés -- ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Re: [Mono-list] Embedded Databases in .NET/Mono
Haha, that's true indeed, Jorge :-) Anyway, in the meantime, I solved the issue like this: I am using Mono.Data.Sqlite on both Windows/.NET and Mono. That works perfectly and saves me implementing two different APIs. As the Mono.Data.Sqlite is a managed provider, the only dependency is sqlite.dll, which is in the Public Domain and also works on both .NET and Mono. So basically, I achieved the goal of bundling all necessary pieces and sticking to open source / free software. Thanks for giving it a thought, though!
