Subject: [Bug c/16331] New: x86-64 inline asm register constraints insufficient WRT ABI
X-Bugzilla-Reason: CC
X-SW-Source: 2004-07/txt/msg00148.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

An x86-64 version of gcc 3.3.3 does not allow inline asm to specify constraints
for all the available registers.  Particularly, since r8 and r9 are used in the
ABI, it would be very beneficial to ensure that parameters to a function called
from inline assembly reside in the proper registers.
