Subject: [PATCH] x86: Fix -Os build (BZ #29576)
|
|
|
|
The compiler might transform __stpcpy calls (which are routed to
|
|
__builtin_stpcpy as an optimization) to strcpy and x86_64 strcpy
|
|
multiarch implementation does not build any working symbol due
|
|
ISA_SHOULD_BUILD not being evaluated for IS_IN(rtld).
|
|
|
|
Checked on x86_64-linux-gnu.
