Subject: [PATCH 21/21] OvmfPkg/Sec: fix stack switch
|
||||
|
||||
The ebp/rbp register can either be used for the frame pointer or
|
||||
as general purpose register. With gcc (and clang) this depends
|
||||
on the -f(no-)omit-frame-pointer switch.
|
||||
|
||||
This patch updates tools_def.template to explicitly set the compiler
|
||||
option and also add a define to allow conditionally compile code.
|
||||
|
||||
The new define is used to fix stack switching in TemporaryRamMigration.
|
||||
The ebp/rbp must not be touched when the compiler can use it as general
|
||||
purpose register. With version 12 gcc starts actually using the
|
||||
register, so changing it leads to firmware crashes in some
|
||||
configurations.
