I want to cross-compile for avrs, so I installed cross-avr-gcc9, but the rpm is
HUGE. Look:
https://download.opensuse.org/repositories/devel:/gcc/openSUSE_Factory/x86_64/?C=S;O=D
cross-avr and cross-rx binaries seem to be unstripped -- no debuginfo package,
the debuginfo is inline.
Picking some of the files from the rpm:
187818848 Sep 23 16:21 /usr/lib64/gcc/avr/9/cc1
199320384 Sep 23 16:21 /usr/lib64/gcc/avr/9/cc1plus
179107056 Sep 23 16:21 /usr/lib64/gcc/avr/9/lto1
Almost 200M each...
# objdump -h /usr/lib64/gcc/avr/9/lto1 |grep \\.debug
31 .debug_aranges 0000db70 0000000000000000 0000000000000000 00d21db0 2**4

On the other hand, from cross-arm-gcc9:
18859160 Aug 23 14:00 /usr/lib64/gcc/arm-suse-linux-gnueabi/9/cc1
20189880 Aug 23 14:00 /usr/lib64/gcc/arm-suse-linux-gnueabi/9/cc1plus
17903416 Aug 23 14:00 /usr/lib64/gcc/arm-suse-linux-gnueabi/9/lto1
By the order of magnitude smaller: around 20M.
# objdump -h /usr/lib64/gcc/arm-suse-linux-gnueabi/9/lto1 |grep \\.debug
<Nothing>
So stripping lto1 manually:
# cp /usr/lib64/gcc/avr/9/lto1 .
# strip /usr/lib64/gcc/avr/9/lto1
# ll -h lto1 /usr/lib64/gcc/avr/9/lto1
-rwxr-xr-x 1 root root 171M 1.������j 09.07 lto1
-rwxr-xr-x 1 root root 14M 1.������j 09.07 /usr/lib64/gcc/avr/9/lto1
So what went wrong during the build?
