Preston Gurd 82cac0acc0 Trivial change to make the test use -mcpu=generic so as to avoid 
a failure if run on an Intel Atom with post RA instruction scheduling.

Richard Smith 12da79b859 Fix incorrect atomics codegen introduced in r154705, and extend test to catch it.

Richard Smith 3e8f1f6aea Fix X86 codegen for 'atomicrmw nand' to generate *x = ~(*x & y), not *x = ~*x & y.

NAKAMURA Takumi 7681b41720 test/CodeGen/X86/atomic_op.ll: Rename @main to @func. Extra sequences will be inserted to @main as prologue on cygming, to fail.

Chris Lattner e479e9643b give LCMPXCHG_DAG[8] a memory operand, allowing it to work with addrspace 256/257

Dan Gohman 0d4bbf2c4a Remove obsolete -f flags.

Dale Johannesen 5afbf510aa Add support for 8 and 16 bit forms of __sync 
builtins on X86.

Change "lock" instructions to be on a separate line.
This is needed to work around a bug in the Darwin
assembler.

Mon P Wang 2c839d4b1e Added support for overloading intrinsics (atomics) based on pointers 
to different address spaces.  This alters the naming scheme for those
intrinsics, e.g., atomic.load.add.i32 => atomic.load.add.i32.p0i32

llvm-svn: 54195
 2008-07-30 04:36:53 +00:00
Mon P Wang 6a490371c9 Added MemOperands to Atomic operations since Atomics touches memory. 
Added abstract class MemSDNode for any Node that have an associated MemOperand
Changed atomic.lcs => atomic.cmp.swap, atomic.las => atomic.load.add, and
atomic.lss => atomic.load.sub

llvm-svn: 52706
 2008-06-25 08:15:39 +00:00
Mon P Wang 3e58393c3d Added addition atomic instrinsics and, or, xor, min, and max.
