![]() This change is focussed on simplifying `Support/Host.h` to only do target detection. In this case, this function is close in usage to existing functions in `Support/Threading.h`, so I moved it into there. The function is also renamed to `llvm::get_physical_cores()` to match the style of threading's functions. The big change here is that now if you have threading disabled, `llvm::get_physical_cores()` will return -1, as if it had not been able to work out the right info. This is due to how Threading.cpp includes OS-specific code/headers. This seems ok, as if threading is disabled, LLVM should not need to know the number of physical cores.

llvm/lib/Support/Unix README =========================== This directory provides implementations of the lib/System classes that are common to two or more variants of UNIX. For example, the directory structure underneath this directory could look like this: Unix - only code that is truly generic to all UNIX platforms Posix - code that is specific to Posix variants of UNIX SUS - code that is specific to the Single Unix Specification SysV - code that is specific to System V variants of UNIX As a rule, only those directories actually needing to be created should be created. Also, further subdirectories could be created to reflect versions of the various standards. For example, under SUS there could be v1, v2, and v3 subdirectories to reflect the three major versions of SUS.
