GNU Arm Embedded Toolchain

Why is the gcc-size-libstdcxx build required?

Asked by Pitchumani Sivanupandi

Task [III-5] gcc-size-libstdcxx build

Is this build used to generate optimized libraries?

Function "copy_multi_libs" copies libraries to installation with _s suffix. But *crt.o files are replaced; no need to have _s suffix version of crt0.o files?

This step builds size optimized libstdc++.a

crt0.o is necessary for nano library, while in the same time it won't break normal newlib, so we just copy and use the nano version here.

Thanks.
