Subject: Re: Align linkerscript symbols according to ABI
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9596ca8194b0b829f7392f5da773026b7aa293fd;p=binutils-gdb.git

Re: Align linkerscript symbols according to ABI

Align dot before symbols defined outside of output sections.  Before _end
is already aligned.

	* scripttempl/elf.sc (def_symbol): Tidy excess space.
	(_edata): Align before emitting symbol when SYMBOL_ABI_ALIGNMENT.
