Transitive closures of architectural extensions have to be manually maintained
for AARCH64_OPT_EXTENSION list. Currently aes, sha2 and sha3 extensions add
AARCH64_FL_SIMD has their dependency - this does not automatically pull in the
transitive dependence of AARCH64_FL_FP from AARCH64_FL_SIMD's definition. As
described the transitive closure/dependence has to be maintained manually.
This patch adds AARCH64_FL_FP to each of these crypto extensions' dependence
set. Automatic transitive closure maintenance is fixed on trunk in commit
11a113d501ff64fa4843e28d0a21b3f4e9d0d3de.
gcc/ChangeLog:
* config/aarch64/aarch64-option-extensions.def (aes, sha2, sha3):
Update AARCH64_OPT_EXTENSION definition of architectural dependence for
defintion of aes, sha2 and sha3 with AARCH64_FL_FP.
