Subject: How to GC unused eh_frame ?
Date: Mon, 6 Jun 2022 19:44:32 +0800	[thread overview]

Hi guys,


	I compiled C++ source codes with compiler’s option as '-ffunction-sections -fdata-sections -Wl,--gc-sections’,
	and I found that some unused code size of ‘eh_frame’s which are come from unused functions are linked together into output elf file :(

	I want to know whether Binutils has a nice way or configure to tell AS to split monolithic ‘eh_frame’ to <function>.eh_frame like ‘.text.<function>’ ?
	and then the unused <function>.eh_frames will been GCed :)

	Any suggestions ?

Regards,

— Jojo
