Hello there!

Neither the toolchain integration nor the toolchain has changed in this aspect between STM32CubeIDE version 1.6.1 and 1.7.0.

It seems more likely that the embedded software is using the KEEP parameter or similar to ignore the discard.

Maybe you could compare the embedded software versions between the different versions.
