From-SVN: r256736
Add -mfunction-return= option to convert function return to call and
return thunks. The default is 'keep', which keeps function return
unmodified. 'thunk' converts function return to call and return thunk.
'thunk-inline' converts function return to inlined call and return thunk.
'thunk-extern' converts function return to external call and return
thunk provided in a separate object file. You can control this behavior
for a specific function by using the function attribute function_return.
Function return thunk is the same as memory thunk for -mindirect-branch=
where the return address is at the top of the stack:
__x86_return_thunk:
call L2
L1:
pause
lfence
jmp L1
L2:
lea 8(%rsp), %rsp|lea 4(%esp), %esp
ret
and function return becomes
jmp __x86_return_thunk
-mindirect-branch= tests are updated with -mfunction-return=keep to
avoid false test failures when -mfunction-return=thunk is added to
RUNTESTFLAGS for "make check".
