Subject: [PATCH 018/124] LoongArch: Prepare static PIE support
|
||
|
|
|
||
|
|
Static PIE allows us to extend the ASLR to cover static executables and
|
||
|
|
it's not too difficult to support it. On GCC side, we just pass a group
|
||
|
|
of options to the linker, like other ports with static PIE support.
|
||
|
|
|
||
|
|
The real implementation of static PIE (rcrt1.o) will be added into Glibc
|
||
|
|
later.
|
||
|
|
|
||
|
|
gcc/ChangeLog:
|
||
|
|
|
||
|
|
* config/loongarch/gnu-user.h (GNU_USER_TARGET_LINK_SPEC): For
|
||
|
|
-static-pie, pass -static -pie --no-dynamic-linker -z text to
|
||
|
|
the linker, and do not pass --dynamic-linker.
