This string represents the custom optimization level that will be
used if DEBUG_CUSTOMOPT.
config DEBUG_OPT_UNUSED_SECTIONS
bool "Optimization to eliminate the unused input sections"
default y
depends on ARCH_TOOLCHAIN_GNU
---help---
Use these options on systems where the linker can perform optimizations
to improve locality of reference in the instruction space. Most systems
using the ELF object format have linkers with such optimizations.
Enable this option to optimization the unused input sections with the
linker by compiling with " -ffunction-sections -fdata-sections ", and
linking with " --gc-sections ".
