FAQ answer

How do I install the library?

Ddr-ArdMeg is distributed as source code only. In other words:

1. Download the source file.

2. Decompress the downloaded file to a suitable directory.

3. Import the CPP- and H-files into your project.

Recomended compiler flags are:

-Os -std=c++11 -fshort-enums -ffunction-sections -fdata-sections
-fno-exceptions

Recomended linker flags are:

-mrelax -Wl,--gc-sections

I have also had some success with the -flto flag (link time optimization). The best case reduced code size by 15%, no improvement in performance. The worst case increased code size by about 10%.

There are obviously a plethora of other compiler/linker flags that may have impact on performance and code size. However, the settings above have, during the development of Ddr-ArdMeg, consistently generated the smallest and fastest code for the library. No other -Ox flag has yet beaten -Os.

Note

If your personal coding style requires another -Ox flag than -Os in order to reach acceptable size and performance, the size of Ddr-ArdMeg may increase and the performance may decrease.
