Re: Problem with gdb debug gcc
[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
Hey,
(gdb) file ./cc1
(gdb) run -I /usr/include /cazy/add.c
my problem is that ,when I creat the break point
(gdb) break main it worked well (gcc/main.c)
but
(gdb) break do_compile, it says Function "do_compile" not defined.
(gcc/toplev.c)
I was having the same problems, and the problem is caused by inlining.
The function do_compile() gets inlined into toplev_main(), at least in
an optimized build.
so i tried to break another function toplev_main() in the same source file
(gdb) break toplev_main it worked (gcc/toplev.c)
Here's what I did to get inlining switched-off and to produce a
debug-capable cc1 compiler (there might be other and possibly better
ways :-)):
configure --disable-bootstrap [...] CFLAGS="-O0 -g -fno-inline
-fno-inline-functions -finline-limit=0"
I think the last two inline options aren't really needed but they
survived from previous problems. -fno-inline should be sufficient, but I
haven't yet tested -fno-inline only.
