Hi!<BR>I have just compiled a trunk version of ScummVM with sword1&2 engines built in. I compared this result with a binariy I built 20080907.<BR>
Old code size:<BR>
0x1797f4(1546228) bytes<BR>
Old static data size:<BR>
0x2ec0(11968) bytes<BR>
<BR>
New code size:<BR>0x19f060(1699936) (difference 153708 bytes)<BR>
<BR>
New static data size:<BR>
0x2ef0 (12016) (difference 48 bytes)<BR>
<BR>
I would n't say that an addition of 150Kb is alot for Symbian OS, but I guess it might be an issue for Nintendo DS.<BR>
<BR>
Cheers<BR>

I guess that is partially due <BR>> to the fact that we now have an XML parser, too... ;) But I figured it <BR>> might be helpful to generate some more data to figure out where we <BR>> might be able to gain the most.<BR>> <BR>> What I did was to compile a "release" binary for both trunk and the <BR>> 0.12.0 branch. So I run<BR>> configure --enable-Werror --enable-release [ lots of --enable- <BR>> ENGINE statements ]<BR>> and made fresh builds for both, on an Apple MacBook Pro, with Apple's <BR>> modified GCC 4.0.1. Our "--enable-release" switch ensures that -O2 is <BR>> passed to the compiler.<BR>> <BR>> I then sorted all *.o files by size of their TEXT segment. Since <BR>> engine code and infrastructure are kind of separate, I did this <BR>> separately independently on both.

Okt 19:16 engines/libengines.a<BR>> <BR>> <BR>> So, the HQx scalers are big, but they are desktop-only, so no problem. <BR>> But then, a very sizable chunk is taken by the new GUI code. The old <BR>> code was not tiny either, but it's clear that libgui.a and <BR>> libgraphis.a grew considerably (also libcommon.a grew, partially due <BR>> to the XML parser, but other changes are in there as well). It sure <BR>> would be nice to get those number back down a bit...<BR>> <BR>> However, take all these numbers with a big grain of salt: We use lots <BR>> of template code these days, and that causes the compiler to generate <BR>> certain chunks of code multiple times, put into each *.o file <BR>> separately. Only during linking time are these duplicates resolved and <BR>> removed. So, the actual contribution of those *.o files to the <BR>> resulting binary might be a lot less than what is listed above.<BR>> <BR>> On the other hand, this immediately hints at a potential way to save <BR>> memory: By carefully reconsidering how we use templates; esp. for the <BR>> container classes, we might be able to save some KB of duplicate code <BR>> (duplicate because the compiler generates it anew for each e.g. <BR>> HashMap variant, even though the code each time is almost or <BR>> completely identical). There are some ways to reduce that.
