Arnaldo Carvalho de Melo 28d2312881 x86: reducing debuginfo size by removing unneeded includes ... I found it strange that the struct sk_buff definition was found inside the DWARF debugging sections in the generated object, so I verified and found that there is no need for the files that bring struct sk_buff definition into this file and verified also that sk_buff is not brought in indirectly too, thru other headers. I went on and removed many other unneeded includes and the end result is: [acme@doppio net-2.6]$ l /tmp/sys_ia32.o.before /tmp/sys_ia32.o.after -rw-rw-r-- 1 acme acme 185240 2008-02-06 19:19 /tmp/sys_ia32.o.after -rw-rw-r-- 1 acme acme 248328 2008-02-06 19:00 /tmp/sys_ia32.o.before Almost 64KB only on this object file! There were no other side effects from this change: [acme@doppio net-2.6]$ objcopy -j "text" /tmp/sys_ia32.o.before /tmp/text.before [acme@doppio net-2.6]$ objcopy -j "text" /tmp/sys_ia32.o.after /tmp/text.after [acme@doppio net-2.6]$ md5sum /tmp/text.before /tmp/text.after b7ac9b17942add68494e698e4f965d36 /tmp/text.before b7ac9b17942add68494e698e4f965d36 /tmp/text.after One of the complaints about using tools such as systemtap is that one has to install the huge kernel-debuginfo package: [acme@doppio net-2.6]$ rpm -q --qf "%{size}\n" kernel-rt-debuginfo 471737710 543867594 [acme@doppio net-2.6]$ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>		2008-04-17 17:40:46 +02:00
