Subject: [PATCH] ppc64/purgatory: Disabling GCC's stack protection
|
|
Git-commit: 7d33c8933ebf8e1788ffff0132b6e08a2388748c

|
Some Linux distributions, like Suse, are turning on the GCC's stack
|
|
protection mechanism by default (-fstack-protector). When building the
|
|
purgatory with this option, this leads to link issues that are revealed at
|
|
runtime when the purgatory is loaded because symbols like __stack_chk_fail
|
|
are unresolved.
|
|
|
|
This patch forces this stack protection mechanism to be turned off when
|
|
building the purgatory on ppc64 BE and LE.
