11.26 --datacompressor=opt

Enables you to specify one of the supplied algorithms for RW data compression.

Note:

Not supported for AArch64 state.

Syntax

--datacompressor=opt

Where opt is one of the following:

on

Enables RW data compression to minimize ROM size.

off

Disables RW data compression.

list

Lists the data compressors available to the linker.

id

A data compression algorithm:

Table 11-2 Data compressor algorithms

id Compression algorithm
0 run-length encoding
1 run-length encoding, with LZ77 on small-repeats
2 complex LZ77 compression

Specifying a compressor adds a decompressor to the code area. If the final image does not have compressed data, the decompressor is not added.

Usage

If you do not specify a data compression algorithm, the linker chooses the most appropriate one for you automatically. In general, it is not necessary to override this choice.

Default

The default is --datacompressor=on.
