Hi Nick,
yesterday was public holiday in Germany, so I answer today.
These are really good news, Thanks.
For my recent experiments with Linux-kernel v4.14.y LTS I used Clang...
#1: version 6.0 from Debian/testing repositories #2: version 7 (svn330207) from <apt-llvm.org>
In these cases I had success (good means boot on bare metal) or it failed (bad verified in Qemu):
bad: CONFIG_PARAVIRT=y and CONFIG_CC_STACKPROTECTOR_STRONG=y good: CONFIG_PARAVIRT=n and CONFIG_CC_STACKPROTECTOR_STRONG=y good: CONFIG_PARAVIRT=y and CONFIG_CC_STACKPROTECTOR_NONE=y
So, the issue is in both Clang versions and I appreciate to have your fix in LLVM/Clang version 6.0.1 as I don't know which version will get into upcoming Debian/buster (version 10, current status: testing).
Hope this helps.
Regards, - Sedat -
