I got the library to compile with the attached patches, though dynamic
loader crashes early.
In buildroot I changed the architecture name by hand from sparc to
sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit)
instructions. This configuration is not supported by QEMU, so I aimed
for pure 64-bit. I think Sparc64 option needs to be added to
buildroot.
The _Qp_ ops seem to be required by the ABI. This and setjmp patches
are just hacks to get the compilation further. The _Qp_ ops can be
found in glibc, would it be OK to use those?
V9 assembler requires declarations for global register use.
The mem* functions in sparc32 directory did not work. They are
actually used only by the hybrid 32-bit + V9 CPU configuration.
