Where is it documented?
Are there differences with the linux ABI?
Particularly I am interested in stack alignment requirement. For example
i386 Solaris, Linux and MacOS have 16 bit stack alignment for procedure
calls. This is reflected in LLVM sources:
if (isTargetDarwin() || isTargetLinux() || isTargetSolaris() || Is64Bit)
stackAlignment = 16;
But FreeBSD is excluded there. Is this a bug in LLVM which magically
doesn't cause crashes or this is correct and FreeBSD doesn't have 16 bit
alignment?
