The default linker behavior is to optimize identical literal values
and remove unnecessary overhead. However, because of a bug in the
linker, this currently results in an error ('call target out of range').
Disable link-time optimizations per default until there is a fix
for the linker and add the option to iss_defconfig.

Enable this to turn on TLB sanity check on each entry to userspace.
|
|
This check can spot missing TLB invalidation/wrong PTE permissions/
|
|
premature page freeing.

If unsure, say N.

Enable this function to disable link-time optimizations.
|
|
The default linker behavior is to combine identical literal
|
|
values to reduce code size and remove unnecessary overhead from
|
|
assembler-generated 'longcall' sequences.
|
|
Enabling this option improves the link time but increases the
|
|
code size, and possibly execution time.

help
|
|
Enable this option to test S32C1I instruction behavior at boot.
|
|
Correct operation of this instruction requires some cooperation from hardware
|
|
external to the processor (such as bus bridge, bus fabric, or memory controller).
|
|
It is easy to make wrong hardware configuration, this test should catch it early.
|
|
|
|
Say 'N' on stable hardware.
