I have also some suggestions about cegcc patches to be more compliant with
other
mingw families (mingw, cygwin).
To sum up it allows to choose EH model (see below for changes) and I
suppose this is
something you wanted to do when I read your comments :
in config/arm/t-wince-pe:
--------------------------
- SHLIB_LC = -lmingw32 -lmingwex -lceoldname -lcoredll
- # Version for cegcc
- #SHLIB_LC = -lc -lcoredll
- # This should go somewhere else. <<<<<<<<<<<<<<
- # We are using SjLj EH.
- EH_MODEL = sjlj
With this change normally we could be able to select dw2 exception model
just by adjusting
DWARF2_UNWIND_INFO in wince-pe.h.
Don't know if it's interesting for us but at least it seems more standard
to do like that.
