Forget all that.
Apparently the compiler on my system has hickups. I hadn't reinstalled a
fresh cegcc.dll for a looong time; apparently I didn't do a full rebuild
+ reinstall since the last upgrade of my Linux system.
The compiler doesn't appear to cope well with the default compiler
options (I'v
I wasn't entirely clear. I started getting the problem I described
below, so I reverted my change, and I'm still getting the problem :-(
I had already discovered that gdb also traps this, and the way to map
these exception codes into explanations. The trouble is now to find out
why this is happeni

This is spooky.
I edited startup.c slightly, recompiled the cegcc.dll . And then,
apparently, something went wrong. Not a single application built with
cegcc wants to run any more, the mingw32ce stuff does still work.
warning: __init_c__: initted = 1
warning: "WCETRACE" not found in registry

SEH is one way. Easier on eVC/MSVC since you have
__try/__catch/__finally there. With gcc you have to do it manually.
On ARM SEH is table based. Take a look at
newlib/libc/sys

Several bits and pieces of input.
1. The gcc manual, ARM section, says -mhard-float is the default.
2. That doesn't seem to be true, because -mhard-float is not accepted
on the compiler command line.
I wrote a very simple program to fiddle with. Compiling it with
different options gives thi
10 matches
