Hello,
I just played with the cflags in $(TOPDIR)/makefile.inc, and came to some interesting results:
Using -Os instead of -O2 decreases the memisosize for the SX100 (on juciphox.. ) from 54e68 to 52848.
Specifying -march=armv5te decreased the memisosize again to 527d8.
The boot time of chdk decreased from ~3 seconds to like 1,5. Means the OSD is shown almost instantly after bootup.
Everything still seems to be working fine, so i suggest those flags get added to SVN? CHDK bootup "feels" a lot better like that..
I know that -Os strips away some debugging symbols, but i dont think those are needed anyways, as the cams gives no debug output, if something goes wrong..
Regards
