Hello Speed Ghost


Then I have recompiled TheIde changing this:
	if(HasFlag("SSE2"))
		cc << " -msse2";// -mfpmath=sse";

and:
Main Pack. Conf.  Compiler Opt         Test time  Problems? 
- GUI SSE2	  No option            2.4 sec    Crash

and I have recompiled again with:
	if(HasFlag("SSE2"))
		cc << " ";//-msse2";// -mfpmath=sse";

and:
Main Pack. Conf.  Compiler Opt         Test time  Problems? 
- GUI SSE2	  No option            9.5 sec    Ok

Koldo,

I thing that is need to set a final source version and propuse for change in svn.
Use as flag I do not thing that it is a good idea. But use in compile options is more transparent.
I thing that it should change Automatic setup (maybe it for win32 only ) for speed option set this command.
for mingw
-msse2 -mfpmath=sse

Hello Ion

Excuse me, I do not understand you very well Sad

After the tests I compile in "GUI" (not in "GUI SSE2") and for the end source if SSE2 code is included I include compiler options "-msse2 -mfpmath=sse" and "/arch:sse2".

Sorry Koldo,

I understood wrong.
The problem is not in u++ but in MinGW TDM 4.4.0?
Right?

I tested for me with old MinGW and have not errors.

Tried it, seems to work fine: it has a big difference with respect to the TDM builds. It uses Dwarf2 for exceptions. Of course, this means one DLL dependency (libgcc_s_dw2-1.dll), regardless of how simple your program is.

Hello Ion

Perhaps yes. It is most probable that the problem is in MinGW as MSC and Gcc (Linux) work.

But perhaps there is in Upp MinGW-Gcc 3 specific code for Windows version that does not work well in version 4.

In fact the benchmark program I have used works the best with MinGW-Gcc 4.4 so not only does not have problems with MinGW, but it gets the maximum optimization, so:

I wonder if additional dll dependency is worth using debugging format which AFAIK U++ doesn`t support? And I`d answer "no".

It's true, and I found this annoying too. Especially considering it's just a 44kb dll.

However, if one uses the '-static-libgcc' option, the dependency is removed. This is something to keep in mind.

Perhaps we would have to propose Theide developers to include this in source code.

A possible implementation could be in file GccBuilder.cpp, line 130, adding this:

	if(HasFlag("WIN32")) {
		cc << " -static-libgcc";


I have compiled Theide with this change and I have debugged programs with MinGW 4.4.0 and without libgcc_s_dw2-1.dll without problems.

Hello all,

I have some experience using simd instructions. On PPC if the data used int SIMD instructions are not aligned ==> crash.
I think it's the same on intel architectures.

Depending on the object creation order for example, on build can work and another crash without having modified any functionnal code.

This is probably one cause of problem.

I often use MINGW. Moreover, MINGW I have, some old version that was included with the UPP. When I was downloading update UPP (for Linux), - I Replace folder uppsrc of wine, - and it works.

By the way - the generation of Win applications under wine, in my opinion, better guarantees against viruses in the final assembly of windows applications.

That is why - I really want to branch MINGW developed, supported and discussed.

SergeyNikitin<U++>( linux, wine )
{
    under( Ubuntu || Debian || Raspbian );
}

I think it should work via build method too, correct? (In that case, I can make it part of mingw autosetup).
