Hi All,

Could someone help to give me some information about the supporting range of libunwind?

The README file states as below.
"""
 Linux/x86-64:    Works well.
 Linux/x86:    Works well.
 Linux/ARM:    Works well.
 Linux/IA-64:    Works well.
 Linux/PARISC:    Works well, but C library missing unwind-info.
 HP-UX/IA-64:    Mostly works but known to have some serious limitations.
 MIPS:          Newly added.
 Linux/AArch64:    Works well.
 Linux/PPC64:    Newly added.
 Linux/SuperH:    Newly added.
 FreeBSD/i386:    Works well.
 FreeBSD/x86-64: Newly added (FreeBSD architecture is known as amd64).
 Linux/Tilegx:  Newly added (64-bit mode only).
"""

What's the difference between 'Newly added' and 'Works well'?
ppc32 is not listed above, but there are ppc32 related codes in libunwind repo. So why is it not listed above? Does it mean that libunwind doesn't support ppc32?

Best Regards,
Chen Qi
