Arm backend: Fix standalone runner link order#20756
Merged

Conversation
Fix the Arm semihosting executor runner link order used by setup_testing.sh. The previous link line placed backend archives before the objects and dependent archives that reference them, so ld could miss bare-metal symbols when building the standalone runners. Group the runner libraries and keep the backend archives in a whole-archive region after clearing their inherited interface link options. This keeps symbols visible to the linker while preserving the existing runner setup. Signed-off-by: Baris Demir <baris.demir@arm.com> Change-Id: Ib1bb2e3a39a3b955556cd67847f74c6ff6d159ab

There was a problem hiding this comment.
Nice OK to merge but if not done it would be good to mind so no unneeded code/data was added now when more stuff might be linked it. e.g. dieas reallt cmsis-nn/timeing_adaptors and ethos_mhu_dumme ethosu_mailbox
and ethosu_uart_cmsdk_apb need to be -whole_archive ?
