Subject: arm: Don't check _DYNAMIC in elf_machine_load_address
X-Git-Tag: glibc-2.27~754
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c34a19ed4b0bcf91ff9671b733f8cfffa111e7f6;p=thirdparty%2Fglibc.git

arm: Don't check _DYNAMIC in elf_machine_load_address

Since arm can't convert access _DYNAMIC via GOT, which needs dynamic
relocation, to PC-relative at link-time, don't check _DYNAMIC in
elf_machine_load_address.

	* sysdeps/arm/dl-machine.h (elf_machine_load_address): Don't
	check _DYNAMIC.
