ArmClang and IAR support compression in the linker. Does gcc support
similar operations of compression?
IAR Compression:
(1) packbits - Compresses with the PackBits algorithm. Thismethod generates
good results for data with many identicalconsecutive bytes.
(2) lz77 - Compresses with the Lempel-Ziv-77 algorithm.This method handles
a larger variety of inputs well, but hasa slightly larger decompressor.

GCC does not contain a linker.
