Does it do a full bootstrap? My gdb session looks more optimized than yours.
Perhaps it is a bug in the host compiler?
My version also does not ever execute this:
Breakpoint 1, linemap_add (set=0x7ffff7ff9000, reason=LC_ENTER, sysp=2,
to_file=0x140e270 "/usr/include/stdc-predef.h", to_line=1)
at /build/gcc-git/src/gcc/libcpp/line-map.c:291
In fact, I don't have this file.
manuel@gcc10:~$ cat /etc/debian_version
6.0.6
so the presence of the file may make a difference (unfortunately, I don't have
root access to gcc10 to fake the file and test).
