Synopsys ARCv3 ISA includes 32-bit ARC HS5x targets and 64-bit ARC HS6x targets. Both CPU families are placed in "arc64" subdirectories as it done for GCC port. Target name arc64 is used for historical reasons and Synopsys ARCv3 baremetal toolchains contain multilib configurations both for 32-bit and 64-bit families. arc32 target name is reserved for 32-bit ARC HS5x targets in case of non-multilib 32-bit builds. Note that libgloss libraries for ARCv3 are compatible with libgloss for ARCv1/2. Thus, Makefile.inc for libgloss uses sources from libgloss/arc directory except crtX.S files.
