Hello all. I am working with an old version of crossgcc (egcs-1.1.1 with binutils-2.9.1) on the M.Core target. The M.Core shares its stack between user mode and interrupt mode. When I debug a C sub-routine under interrupt, I can display the function call list ("where" under gdb) which presents the called functions under both modes. But If I was executing a leaf function (i.e. a function that does not call any other one) before interrupt, I do not see it in the stack: gdb displays the non-leaf functions before interrupt and then the functions under interrupt, including the last function (even if it is a leaf function). Why do the interrupted leaf functions never appear in the stack (under gdb) ? Do you konw if it is a porting problem or if I have to use a special option to compile my application in order to force the compiler to always use the stack, even if the functions are leafs ? (I tried -O0 but it is not sufficient) Thanks a lot for your help. Pierre. ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
