-speculative-execution moving load before store
Hi, A few days ago I stumbled upon a problem where SpeculativeExecution changed the order of a load and a store to the same address. I wrote https://bugs.llvm.org//show_bug.cgi?id=32964 about it but no response there so far. In the input we have store i8 0, i8* @i %.pre = load i8, i8* @i and then in the output the load is moved so it's before the s...

CentOS 6 i386 - meltdown and spectre
I have a clean install, fully updated CentOS 6 32-bit. When I run the Red Hat detection script: https://access.redhat.com/sites/default/files/spectre-meltdown--a79614b.sh it finds that the system is vulnerable. Is this false positive or there is no patches for CentOS 6 32-bit systems? Thank you, -- Peter
