           Summary: libgcc_s.so not compiled without optimization when
                    requested
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: yuri@tsoft.com


I need to have libgcc_s.so without optimization and with debug info.
Following documentation on GCC own site
http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html, I ran make with
overriding compilation flags:

make CXXFLAGS='-g3 -fno-inline -O0' CFLAGS='-g3 -fno-inline -O0' all

But the resulting libgcc_s.so is still optimized. I could see that "-O 2" was
passed to all compiles.

Actually, gcc build process should respect the given to the top-level make
CFLAGS and CXXFLAGS and propagate them to all levels.
