           Summary: GOLD drops STV_PROTECTED status from weak function
                    symbols
           Product: binutils

Object files and shell script to demonstrate the bug

When gold is used to link the LLVM IR files in the uploaded test it drops
the STV_PROTECTED status from the f1 function symbol.  Earlier versions of
gold (2.29 or previous) did not do this.  Nor does the 2.30 bfd linker.

To reproduce install llvm and then run the build.sh script.

Using ld.bfd in the script produces:

   16: 0000000000001000     6 FUNC    WEAK   PROTECTED    6 f1
    8: 0000000000003f10     0 SECTION LOCAL  DEFAULT    8 
   11: 0000000000001010     2 FUNC    LOCAL  DEFAULT    6 f1.2
   14: 0000000000003f10     0 OBJECT  LOCAL  DEFAULT    8 _DYNAMIC
   26: 0000000000001000     6 FUNC    WEAK   PROTECTED    6 f1

whereas ld.gold produces:

   18: 00000000000005b0     6 FUNC    WEAK   DEFAULT    8 f1
    2: 00000000000005c0     2 FUNC    LOCAL  DEFAULT    8 f1.2
   24: 00000000000005b0     6 FUNC    WEAK   DEFAULT    8 f1
