Subject: [ARC] Don't convert _DYNAMIC@ to _GLOBAL_OFFSET_TABLE_
X-Git-Tag: binutils-2_29~342
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7ef0acc15ec011371a3901a997c867165bf7a733;p=external%2Fbinutils.git

[ARC] Don't convert _DYNAMIC@ to _GLOBAL_OFFSET_TABLE_

Historically the arc abi demanded that a GOT[0] should be referencible as
[pc+_DYNAMIC@gotpc].  Hence we convert a _DYNAMIC@gotpc to a GOTPC reference to
_GLOBAL_OFFSET_TABLE_.

This is no longer the case and uClibc and upcomming GNU libc don't expect this
to happen.
