a simple google for "x32 abi":
Right another ABI.
I was mainly concerned about your statement that "the x32 ABI slipped
through the cracks". I cannot find any prior communications about this.
How could I test this?
(I wonder if this can become a robust ABI with current hardware, unless
we pay a major performance price. It seems like address arithmetic by
means of hardware indexing, lea, etc, will be 64-bits, while we want to
compute mod 2^32.)
