I'm not familiar with clang's support for parallel linking, so maybe this isn't what you mean, but GCC supports parallel ltrans for LTO, and IIRC GCC 10 made multithreaded ltrans the default behavior.

'gallerdude didn't mention anything about fabs. Also, these GPUs are fabricated at Samsung, so your comments about TSMC are mostly irrelevant. If the fab was all that mattered, AMD GPUs would be dominating Nvidia, since they have

That name doesn't really distinguish this feature from the normal store-to-load forwarding from the store buffer that processors have been doing for decades, though. I think memory renaming is the probably the best name for it.

The clock signal is not sent because it would require another high-bandwidth wire and would introduce problems of clock skew within a lane. In other words, having a separate clock means you need to ensure that the clock and data signals are

2) Pretty sure Tesla is still not producing 10k cars per week. Their Q2 2020 update shows max quarterly production was ~105k in Q42019, which is ~8k per week. I can't find anything suggesting they have ever peaked over 10k per week. 4)

Yeah, agreed that architectural licensees definitely influence future ARM specifications - e.g. Fujitsu was a major driver behind SVE. IMO, there's an important difference between Apple adding new instructions that are not in the spec,

ARMv8-A supports page sizes of 4k, 16k, and 64k. The specification permits implementations to choose which of these page sizes to implement. See the register ID_AA64MMFR0_EL1.

They are probably just peripherals, like the GPU. I'd be very surprised if Apple strayed from the ARMv8 specification and added new instructions for those accelerators.

Apple does not have a license to add instructions to the ARMv8 ISA. ARMv8 processors designed by Apple must be fully compliant with the ARMv8 instruction set architecture - such are the terms of the license. ARM very recently started allowi
