One of the differences between the ABI and EABI is that the EABI
requires 8 byte alignment of the stack and the ABI requires 16 byte
alignment (EABI, p.28).
Yes, ok. But what is implemented by GCC and glibc? The SVR4 ABI or
the EABI?
In other words: Wolfgang Grandegger wants to know if we must align
"private" stack frames on 8 or 16 byte boundaries...
Wolfgang Denk
linux implements SVR4 with exceptions that we don't return small(8 or less
bytes) structs in r3,r4 as the standard say we should. Could be more things I
have not noticed we are anyway closer to SVR4 than EABI.
