I have a 28069 project which build and links fine under 6.2.11 however attempting the same build using 6.4.9 results in code too large to fit in flash. I've combed the map file and there's not a glaring increase of any single object file. Instead there's a slight increase in the size of every object file.
This project contains mostly cpp files but I'm also building MWare from source at the same time and those object files increase too (not fair comparison though because MWare has been updated between these two builds).
I've tried building with --C89 without any change.
Here are the first few lines from the map files for each build:
6.2.7
003d8000 0000295d SoundEngine.obj (.text)
003da95d 00002045 FrontPanel.obj (.text)
003dc9a2 000011df MidiDevice.obj (.text)
003ddb81 00000dd1 usblib.lib : usbhostenum.obj (.text)
003de952 000009ba rts2800_fpu32.lib : _printfi.obj (.text)
003df30c 000008fb Globals.obj (.text)
6.4.9
003d8000 00002e88 SoundEngine.obj (.text)
003dae88 0000229c FrontPanel.obj (.text)
003dd124 00001455 MidiDevice.obj (.text)
003de579 00000001 rts2800_fpu32.lib : newhandler.obj (.text)
003de57a 00000c01 : _printfi.obj (.text)
003df17b 00000974 Globals.obj (.text)
I can obviously force the project to build with the old tools but I'd like to understand this issue.
Thanks!
