Rename the AttributeImpl* from Attrs to pImpl to be consistent with other code.
Add comments where none were before. Or doxygen-ify other comments.

This reverts r170694.  The operations can be represented in IR without
adding any new intrinsics.

to also remove a trailing space if possible.

For example, removing '__bridge' from:

i = (__bridge I*)p;

should result in:

i = (I*)p;

not:

i = ( I*)p;

Such variables may immediately become nil or may have unpredictable

Before if-conversion we could check if a value is loop invariant
if it was declared inside the basic block. Now that loops have
multiple blocks this check is incorrect.

the script generating it. The test should never be modified manually. If anyone
needs to change it, please change the script and re-run it.

The script is placed into utils/testgen - I couldn't think of a better place,
and after some discussion on IRC this looked like a logical location.

This is supposed to be a mechanical change with no functional effects.

InstrEmitter can generate all types of MachineOperands which revealed
that MachineInstrBuilder was missing a few methods, added by this patch.

Besides providing a context pointer to MI::addOperand(),
MachineInstrBuilder seems like a better fit for this code.

llvm-svn: 170712

This automatically passes a context pointer to MI->addOperand().

Without this patch comparing two equal versions without patch numbers (4.7 for
example) will result in A < B and B < A.

Patch by Simon Atanasyan.

llvm-svn: 170705

Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.

Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).
