            Bug ID: 27127
           Summary: [mips] relocation type R_MIPS_GOT_HI16 conflict with
                    local symbol
           Product: binutils
           Version: 2.34
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org

testcase

option: mips-linux-gnu-gcc generate-global.c -fPIE -pie -mxgot

global          local        addition            .got

R_MIPS_GOT_HI16 R_MIPS_GOT16 got_index = 0xb6f64 0xA7A47F8
64KB*64KB       64KB


relocation item                                               target value
0027a37c  016a9f16 R_MIPS_GOT_HI16  0027a1c0   global_symbol  0x3690000
0027e3e4  00000309 R_MIPS_GOT16      00000000   .text         0x368E114

both mips_got_entry = 0x3690000

but the gp = 0xA6ED894 (0xA6E5895 ~ 0xA6F5894)


Relocation item 0027a37c is a global_symbol,so linker creates mips_got_entry =
0x3690000 with got_index = 0xb6f64, which is equal to target value. Obviously
it,s valid for relocation type R_MIPS_GOT_HI16.
However, when linker relocate item 0027e3e4 with target value 0x368E114, bug
occur. 
relocation truncated to fit: R_MIPS_GOT16 against `.text'
the symbol(0027e3e4) was local,the GOT16 relocation should load the equivalent
of %hi(VALUE)
value = mips_elf_high (value) << 16,
linker calculate mips_got_entry = 0x3690000, which is the same as the former
but invalid.
