Hey Michael,

Just a heads up that AMD posted code for a new chip. After the "Sienna Chiclid" now it's "Navy Flounder". Looks like another Navi2x chip.
This are CIA codenames from AMD.

I just hope AMD delivers graphics chips not a new fish.

I haven't followed LLVM 11 development, does anyone know why -fstack-clash-protection for aarch64/arm64 didn't land yet? Is it looking like it will be added for LLVM 12?

I don't think c++17 is default on LLVM 11. c++14 is still the default. Please provide exact source confirming that c++17 is the default or correct the misinfomation.

Support is currently targeted for LLVM 12.

Whoops, misread that as ++, will correct that aspect.

Wonder if they even finished C++17? The missing pieces were in libc++ so might be different change logs. The official overview says no, but could easily be outdated https://libcxx.llvm.org/cxx1z_status.html

i don't think they depend on standard library support to do the switch

There's a small typo that surprised me until I clicked the link: one bullet reads "- Clang -o behavior better matches GCC." That "-o" (lowercase o) is the mistake as it should be "-O" (capital o). "-O" is the flag for controlling optimizations and is the flag with the behavior change; "-o" is the flag for setting the name of the output file.
