Interesting. My guess is that it's creating a
trampoline on the stack, which calls the real
g(), which nm tells me is at:
080485a6 t g.0
Unfortunately gdb on the Linux server is unable to show
me the instructions:
Reading symbols from a.out...Dwarf Error: Cannot handle DW_FORM_strp in DWARF reader.
But a quick grep for "tramp" in the gcc source finds such
beauties as:
libgcc2.c:1639: /* Make stack executable so we can call trampolines on stack.
and (in function.c):
/* Return the address of the trampoline for entering nested fn FUNCTION.
If necessary, allocate a trampoline (in the stack frame)
and emit rtl to initialize its contents (at entry to this function). */
...and that's about all that I have the stomach for
right now...
