The size increase after enabling options related to ARMv8.3-PAuth is:
+----------------------------+-------+-------+-------+--------+
| | text | bss | data | rodata |
+----------------------------+-------+-------+-------+--------+
| CTX_INCLUDE_PAUTH_REGS = 1 | +40 | +0 | +0 | +0 |
| | 0.2% | | | |
+----------------------------+-------+-------+-------+--------+
| ENABLE_PAUTH = 1 | +664 | +0 | +16 | +0 |
| | 3.1% | | 0.9% | |
+----------------------------+-------+-------+-------+--------+
Results calculated with the following build configuration:
make PLAT=fvp SPD=tspd DEBUG=1 \
SDEI_SUPPORT=1 \
EL3_EXCEPTION_HANDLING=1 \
TSP_NS_INTR_ASYNC_PREEMPT=1 \
CTX_INCLUDE_PAUTH_REGS=1 \
ENABLE_PAUTH=1
