Hi,
Apologies for the bad posting style (I don't have the
original email handy), but shouldn't _gnu_cmse_nonsecure_call be defined
with the .global directive in the below hunk (to make it visible when linking)?

+__gnu_cmse_nonsecure_call:
Right now, it ends up as a local symbol, and compiling and linking a
program with cmse_nonsecure_call (say cmse-11.c), results in a linker
error - the linker doesn't find the symbol even if it is present in
libgcc.a. I found the problem that way - dumping symbols for my variant
of libgcc.a and grepping showed the symbol to be available but local.

Hi Senthil,
Thanks for catching that!
Cheers,
