New Revision: 203962<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=203962&view=rev" target="_blank">http://llvm.org/viewvc/llvm-project?rev=203962&view=rev</a><br>
Log:<br>
Correctly handle an ELF symbol defined with "a = b + expr".<br>
<br>
We were marking the symbol as absolute instead of computing b's offset + the<br>
expression value.<br>
<br>
This fixes pr19126.<br>
