The expected behavior is "<optimized out>" like what gcc-6.5.0 does as follows: $ gcc-6 -O3 out.c abc.c -g $ gdb-trunk -x cmds -batch a.out Breakpoint 1 at 0x547: file abc.c, line 8. Breakpoint 1, main () at abc.c:8 8 optimize_me_not(); $1 = <optimized out> Kill the program being debugged? (y or n) [answered Y; input not from terminal] [Inferior 1 (process 17644) killed]
