Subject: gold -Ttext=.. workaround
X-Git-Tag: v3.3.0~203
X-Git-Url: http://zhaoyanbai.com/repos/rndc.html?a=commitdiff_plain;h=6611dddc317baa4da4ebe62a3472a88df482f8bd;p=minix.git

gold -Ttext=.. workaround

replace invocations of -Ttext=.. with --section-start=.text=.. for
gnu gold-ld. it was giving very weird results when given page-rounded
values. --section-start=.text=.. works for both bfd-ld and gold.
