The gcc.mk file is passing --enable-target-optspace to gcc configure script, to ask for space-optimized (-Os) target libraries. However, passing this option has the effect of overriding any custom CFLAGS_FOR_TARGET or CXXFLAGS_FOR_TARGET values that may be passed. These are some situations when it is required to pass custom flags on buildong of libgcc: * Default flags "-g -Os" lead to build isses as with PowerPC on gcc 4.5 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810) * Particular CPU requires specific instructions for HW support * Deep optimizations Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Peter Korsgaard <peter@korsgaard.com> Cc: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |
