Solar,
We are trying to resolve BSDIcrypt problems on Win64. It seems to get
stuck somewhere in an endless loop on Win64. DEScrypt, LM and Deepika's
formats are fine.
I can't see any pop corresponding to this push:
DES_bs_finalize_keys_25:
leaq DES_bs_crypt_25_body(%rip),tmp1
pushq tmp1
DES_bs_finalize_keys:
...
What's with that? And while we're at it,
DES_bs_crypt:
PROLOGUE
cmpl $0,DES_bs_all_keys_changed(%rip)
jz DES_bs_crypt_body
pushq %rdi
call DES_bs_finalize_keys
popq %rdi
What good does the push/pop of %rdi do here? I can't see it being used
anywhere.
