- Subject: modified x86 ABI
At EMC we have a version of GCC which targets the x86 with a non
standard ABI -- it produces code for 64 bit mode mode, but with types
having the 32 bit ABI sizes. So, ints, longs, and pointers are 32
bits -- that is, it's ILP32 rather than LP64 -- but with the chip in
64 bit mode.
Actually, pointers are somewhat schizophrenic -- software 32 bits,
hardware 64 bits.
Currently the changes are against 3.4.6 and are not yet
If this set of changes was cleaned up, finished, and made relative to
top of trunk rather than relative to 3.4.6, would people be interested
Put another way, should I bother to post them to gcc-patches (probably
3-6 months out) for possible inclusion into gcc?
