Subject: [PATCH 1/3] elf.h: resynchronize with glibc elf.h | ||
|
||
This commit adds two symbols (SHT_MIPS_XHASH and DT_MIPS_XHASH) found | ||
in glibc, and updates the value of DT_MIPS_NUM. These changes were | ||
made to glibc in 23c1c256ae7b0f010d0fcaff60682b620887b164 on | ||

Subject: [PATCH 2/3] patchelf.cc: handle DT_MIPS_XHASH and .MIPS.xhash | ||
|
||
glibc changed their ABI in commit | ||
23c1c256ae7b0f010d0fcaff60682b620887b164 on 2019-Aug-29, by changing | ||
the structure of the .gnu.hash data on MIPS and moving it to a | ||
different section. We need to adapt to this change by glibc. | ||
|
||
Closes #368 | ||
