multilib question: skip x32
by jr_bob_dobbs from LinuxQuestions.org on (#5MYC1)
The background:
So I've been thinking of building an LFS system again. Just the other day I heard that there is now a multilib version of the book. Yay! That will let me build a proper Wine and run some Windows programs, not to mention run a small number of old 32-bit Linux binaries. I've been going through the book to decide the if how and when of a possible system.
To my surprise, the book has 64bt, 32 bit ... and a third mode of x32. If I understand correctly, x32 is mostly 32 bit opcodes, addressing a 32-bit memory space, but using the full full-sized 64-bit registers?
The question:
If my only interest is running two or so older 32-bit Linux binaries and some 32 & 64 bit Windows programs in Wine, can I omit x32?
Thank you.
