Version 6.50, Release Candidate #2 available

[Pelle]

Pelles C version 6.50, Release Candidate #2, is now available for download:
http://www.smorgasbordet.com/pellesc/download.htm

German translation, bugfixes in the compiler and IDE, syntax highlighting and help for (most) intrinsics in the source code editor.

Great , thank you, I will look at it!

Edit: my first tests run good! 

[Robert]

When using the BCX BASIC to C translator .exe compiled with either  Pelle's C Version 6.50, Release Candidate #1 or Pelle's C Version 6.50, Release Candidate #2,  most of the lines in the C file output by the BCX translator contain a double CR/LF, that is, 0D0A0D0A instead of 0D0A.

This problem does not occur when the BCX translator is compiled with the Microsoft C/C++ compiler.

Pelle,

Thank you for RC2.

Unfortunately, I must concur with Robert's report of the double CRLF's ... 

The good news is that RC2 compiles BCX 6.2.1 in 1 minute 5 seconds, much faster than the 5 minutes 40 seconds of RC1

By way of comparison, Microsoft 32-bit C/C++ Optimizing Compiler Version 14.00.50727.762 compiles BCX 6.2.1 in 0 minutes 35 seconds

BCX compiled with Pelles C translates itself 15% faster than BCX compiled with MSVC...

I hope this was helpful.

[Vortex]

Thanks for this new release.

This version can compile SQLite 3.7.3 amalgamation version.
Good work Pelle !

Thank you, Pelle - get_rule error has gone!

There are some other "features" I have discovered.
The first one:
Create include file dummy.h with single definition

Code Select Expand

#ifndef __DUMMY_H__
#define __DUMMY_H__
int __cdecl dummyfunc(int);
#endif // DUMMY_H__

Create folder MyInclude under C:\Program Files\PellesC
Put dummy.h into MyInclude
Add MyInclude to Folders in Tools->Folders->Options->Include
Rebuild sysdefs.tag
Add #include <dummy.h> to project source file
Try to compile and get the following error:
fatal error #1035: Can't find include file <dummy.h>

Move MyInclude folder to C:\Program Files\PellesC\Include
Add it to Folders in Tools->Folders->Options->Include (removing the old one)
Rebuild sysdefs.tag
Try to compile and get the same error:
fatal error #1035: Can't find include file <dummy.h>

Copy (not cut) dummy.h from MyInclude to C:\Program Files\PellesC\Include
Try to compile - everything is OK!

Add

Code Select Expand

int a = dummyfunc(1) to source file;
Obviously it will fail on build, because we don't have .lib file, but we are speaking about compilation.
Compile - ok, right click on dummyfunc, choose "Go to definition of:", dummy.h file is opened.
Right click on dummy.h tab, choose "Open containing folder":
C:\Program Files\PellesC\Include\MyInclude is opened!

A bit strange behavior, isn't it? Also I noticed that when I add any external folder to includes, the error message from my post http://forum.pellesc.de/index.php?topic=3323.msg12674#msg12674 comes back.

The second one:
In debugging mode background of current line remains pink when you leave debugged procedure, even after pressing F5  - it badly confuses, because you think you are still in debugging.

The last "feature":
Main toolbar loses focus after click on any other project window ("Auto", "Watch", "Locals" etc). In order to bring focus back to main toolbar you should click in source code area (clicking on IDE window does nothing).

Robert, MrBCX regarding double CR/LF:
I don't know much about the BCX translator, nor how to use it. I'm not terribly interested in going through a big auto-translated C file to find a *possible* bug (it could be anything, at this point). Can you boil down the problem to a C file of a more manageble size?

Pelle,

BCX uses simple disk i/o as you'll see in the samples from the generated BCX source code below.


The first 36 lines are emitted correctly - only one crlf

BCX CR/LF

Error in speed optimization ?

BINGO!

Nice detective work timovjl !

Compiling with /Os fixes the problem and /Ot causes the problem in RC 6.50

BCX CR/LF

Error in speed optimization ?

BINGO!

Nice detective work timovjl !

Compiling with /Os fixes the problem and /Ot causes the problem in RC 6.50

The problem also exists with a BCX compiled with the /Ox option.

The __cdecl directive appears to not work. For example:

Code Select Expand


static int __cdecl LookupCompare(WINDOW_LOOKUP *w1, WINDOW_LOOKUP *w2)
{
    // compare
}


I keep getting this warning when I have code that points to the above function. (It doesn't appear when I switch the compiler convention to __cdecl.)

Assignment of 'int __stdcall function(const void *, const void *)' to 'int __cdecl function(const void *, const void *)

[lamer]

If you type something in source file and then close IDE - the file is saved without prompt.
If you close only the tab with source file, but not IDE - the prompt to save changes appears.
It's a bit dangerous to save without prompting

[ianammo]

Only recently discovered Pelles C, and have been doing some testing with RC2, all going well.  However there seems to be missing a header file - If I include <emmintrin.h> or <xmmintrin.h>, compile gives warning - "Can't find include file <mmintrin.h>". Have checked, and file doesn't appear to have be installed.

Thanks.
