altimumdelta 77dc289517 CPUDetect: Indicate slow PDEP/PEXT only for Zen1/+/2 (Family 23) 2020-11-08 14:27:24 +01:00
Techjar 185e49d2a9 x64CPUDetect: Add flag for slow PDEP/PEXT on AMD Zen
For some unknown reason PDEP and PEXT are ridiculously slow on AMD Zen
architecture.

Fiora 72c96c20d3 JIT: more optimizing of float ops based on known input characteristics
If the inputs are both float singles, and the top half is known to be identical
to the bottom half, we can use packed arithmetic instead of scalar to skip
the movddup.

This is slower on a few rather old CPUs, plus the Atom+Silvermont, so detect
Atom and disable it in that case.

Also avoid PPC_FP on stores if we know that the output came from a float op.

Augustin Cavalier 51700a2b68 Fix the brand/cpu_string reversal.
Before this commit, the two were reversed ("cpu_string" had the brand, e.g. "AuthenticAMD"; and "brand_string" had the CPU type, e.g. "AMD Phenom II X4 925").

magumagu d905cbfd5d Don't set DAZ on x86 in non-IEEE mode.
I have no idea why we were using it in the first place; it doesn't match
the behavior of PPC NI flag.

Pierre Bourdon d2de1ddabc CPUDetect: add support for MOVBE detection 2014-04-11 23:29:03 +02:00
Ryan Houdek 4f02132f93 Make our architecture defines less stupid.
Our defines were never clear between what meant 64bit or x86_64
This makes a clear cut between bitness and architecture.
This commit also has the side effect of bringing up aarch64 compiling support.
