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.
