and pointer types safely if they only do so when the sizes are the same.
llvm-gcc is such a client.

llvm-svn: 72026

between integers and pointers when the source type is marked signed,
since inttoptr and ptrtoint always use zero-extension when the destination
is larger than the source.

Some comment cleanup.

don't have this header.

avoid ambiguity with the word "use" in IVStrideUse.

consistency with other routines that use a null Loop* to mean code
not contained by any loop.

entering a loop is a non-split critical edge.

It doesn't matter for piped input, but it's annoying when typing at the

Significantly improve Atomic.h by pulling in code from libatomic_ops by HP.  This is a little outdated, but reasonably complete.

llvm-svn: 71973

Remove the volatile marker from the cas_flag typedef, fixing some warnings.  
 It's now the client's resposibility to add it in when needed

Back out the thread-safe ManagedStatic for now.  Too many people have too many problems with it for the moment.

started causing problems.

to avoid an ambiguous else.

When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.

llvm-svn: 71919

The following is checked:

* Operand counts: All explicit operands must be present.

* Register classes: All physical and virtual register operands must be
  compatible with the register class required by the instruction descriptor.

* Register live intervals: Registers must be defined only once, and must be
  defined before use.

The machine code verifier is enabled with the command-line option
'-verify-machineinstrs', or by defining the environment variable
LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the
verifier errors.
