Hello Sender Ghost
I have put the little benchmark in Upp "Bombs" example and it worked well without and with -msse2 (with this it worked three times faster).
...........
Any way I suggest anybody to update MinGW as much as possible.
And it also would be good to:
- either add to "Speed" option more optimisations like "-msse2" or "/arch:SSE2"
- or add other option like "Max Speed" (or other name) to include maximum optimizations that are less reliable, like -msse2 in your computer.
I do not know if there are more configurations, but I have been very surprised. Look in MSC9 test: from 17.3 to 2.1 seconds 
Best regards

Very interesting things. I agree to add this option to "Speed" when autobuild (Automatic setup), do not need to add new option "Max Speed".
For me works fine and speed time is more faster. can you tell how to upgrade minGW for u++? is any specific configuration or is standard installation of minGW?

Hello all
One thing I did not know:
- TheIde compiled with MSC can debug MinGW and MSC
- TheIde compiled with MinGW can debug MinGW but hungs trying to debug MSC.
In the last case TheIde outputs an Exclamation window with "Error invoking gdb !", strange as I am trying to compile with MSC.
This is in the file gdb.cpp:
bool Gdb::Create(One<Host> _host, const String& exefile, const String& cmdline)
{
host = _host;
dbg = host->StartProcess("gdb " + GetHostPath(exefile));
if(!dbg) {
Exclamation("Error invoking gdb !");
return false;
}
Gdb::Create is called in the same file in:
One<Debugger> GdbCreate(One<Host> host, const String& exefile, const String& cmdline)
{
Gdb *dbg = new Gdb;
if(!dbg->Create(host, exefile, cmdline)) {
delete dbg;
return NULL;
}
return dbg;
}
And GdbCreate is called in file Debug.cpp in:
void Ide::BuildAndDebug(bool runto)
{
...
#ifdef COMPILER_MSC
debugger = builder == "GCC" ? GdbCreate(host, target, runarg) : PdbCreate(host, target, runarg);
#else
debugger = GdbCreate(host, target, runarg);
#endif
So it seems the code forces to use Gdb although the compiler used is MSC. This could be the problem.

Hello, Koldo.
TheIDE in Optimal mode will compile packages and selected files with "Optimize for speed" option using defined compiler string (by default: "-O3 -ffunction-sections") and other files with "Optimize for size" compiler string (by default: "-Os -finline-limit=20 -ffunction-sections") as installed in Build methods for GCC builder.
When we use SSE2 flag in main package configuration TheIDE will add "-msse2 -mfpmath=sse" string to compiler options (both for speed and size).
I suggested to use O2 compiler option instead of O3 when using SSE2. Because in my configuration, e.g. TheIDE and AddressBook, U++ GUI application crashes when started. The cause can exists in following areas:
- GCC compiler itself;
- U++ algorithms which used in GUI applications (area can be limited by "Opimize for speed" files);
- Operating system;
- Hardware configuration.
Yes, I can run Bombs U++ GUI application, but it crashes when I click on "Game" submenu.

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

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.

Hello Ion
Excuse me, I do not understand you very well 
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".
Best regards
Koldo

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.

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.
Best regards

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