Hii,
I had a small doubt about all the source code/procedures that a code
goes through. Where can I read more about it? For instance, when I am
debugging smpschededf02.exe with gdb, It starts with
bsps/sparc/shared/start/start.S, line 107(Why did it start with
start.s?) and the last line of this file is:
mov %g0, %o0 ! command line
call SYM(boot_card) ! does not return
sub %sp, 0x60, %sp ! room for boot_card to save args
After this it starts executing bsps/shared/start/bootcard.c: line 53 .
How did this happen? Is it because of call? If yes, why was sub
executed(in gdb) before executing code from bootcard.c?
I hope I am not trying to going too deep into this. I just want to
have a overall picture of how a code gets executed. This is necessary
for writing your own code in RTEMS, right?
