m68010+gcc optimization -O3(BSD release build’s default) and -fPIC problem?

error occured following function:

• ossl_ed25519_verify
• ossl_ed25519_public_from_private
• ossl_x25519
• ossl_x25519_public_from_private

and following asm code is generated and got error.

in the first place N/sun2 arch don’t build shared library(due to m68010 restriction?), -fPIC is completely useless.

[Takehiko NOZAKI]

reduce optimization down to -O2 or -Os is ok with -fPIC.

[Takehiko NOZAKI]

and more, aes-m68k.S uses m68020 instruction, can’t build m68010-gcc.

[Takehiko NOZAKI]
