Hi Tom,
I didn't think this would result in a size increase. Could you elaborate?
Alright. So for background, if you build with tools/buildman/buildman rather than just "make" directly there's some handy tools like "bloat" detection, which shows function size changes from build A to build B. Doing something like this will show the changes for pine64_plus for example export SOURCE_DATE_EPOCH=`date +%s` ./tools/buildman/buildman -o /tmp/pine64_plus -devl -SBC pine64_plus ./tools/buildman/buildman -o /tmp/pine64_plus -devl -SsB pine64_plus
That shows in the end: aarch64: (for 1/1 boards) all +551.0 rodata +107.0 text +444.0 pine64_plus : all +551 rodata +107 text +444 u-boot: add: 2/0, grow: 0/-1 bytes: 452/-8 (444) function old new delta fit_find_config_node - 264 +264 board_fit_config_name_match - 188 +188 image_source_script 520 512 -8
And it's that growth, over 722 configs, that I'm concerned with.
