Hi All,
This sets the L1 data cache size for some cores based on their size in their
Technical Reference Manuals.
Today the port minimum is 256 bytes as explained in commit
g:9a99559a478111f7fbeec29bd78344df7651c707, however like Neoverse V2 most cores
actually define the L1 cache size as 64-bytes. The generic Armv9-A model was
already changed in g:f000cb8cbc58b23a91c84d47d69481904981a1d9 and this
change follows suite for a few other cores based on their TRMs.
This results in less memory pressure when running on large core count machines.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Ok for master?
Thanks,
Tamar
gcc/ChangeLog:
* config/aarch64/tuning_models/cortexx925.h: Set L1 cache size to 64b.
* config/aarch64/tuning_models/neoverse512tvb.h: Likewise.
