Hi,
Support for the x32 psABI:
http://sites.google.com/site/x32abi/
will be added into Linux kernel 3.4. X32 uses the ILP32 model for x86-64
instruction set with size of long and pointers == 4 bytes. X32 is
already supported in GCC 4.7.0 and binutils 2.22. I will submit a
series of patches to enable x32 support in glibc. My patches extend
x86-64 target to support x32. Most of them are limited to x86-64
subdirectories. My patches should gradually add x32 support without
breaking any other targets and x32 should be anabled with the last
patch applied.
Thanks.
H.J.
