Dear all,
I use arm-none-eabi-gcc 7.2.1 in my project, when I want to use -flto option to optimize bin size, error shows:
../../../tools/gcc/linux/gcc-arm-none-eabi/bin/arm-none-eabi-ar: creating /proj/lib_m.a../../../tools/gcc/linux/gcc-arm-none-eabi/bin/arm-none-eabi-ar: /proj/src/n1.o: plugin needed to handle lto object../../../tools/gcc/linux/gcc-arm-none-eabi/bin/arm-none-eabi-ar: /projsrc/nb_data.o: plugin needed to handle lto object
what's wrong with my code?
Thank you for your replay.
sorry for late, I have resolved the problem, in build I add -ffat-lto-objects, and in link I add --use-linker-plugin, so the "plugin needed to handle lto object" message appear no more!
