Subject: R_AARCH64_LDST8_ABS_LO12_NC is effectivelly relative.
X-Git-Tag: llvmorg-3.9.0-rc1~13347
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9a3bb54b2e0ac170b9ff05f0655d43795846502c;p=platform%2Fupstream%2Fllvm.git

R_AARCH64_LDST8_ABS_LO12_NC is effectivelly relative.

It only sets the low bits and given the page alignment of PT_LOAD the
dynamic linker can only change the high ones.
