Sean Silva 287e7d275c docs: Cleanup trailing whitespace. 
llvm-svn: 170799
 2012-12-20 22:59:36 +00:00
Jakob Stoklund Olesen 2455b58551 Require the two-argument MI::addOperand(MF, MO) for dangling instructions. 
Instructions that are inserted in a basic block can still be decorated
with addOperand(MO).

Make the two-argument addOperand() function contain the actual
implementation. This function will now always have a valid MF reference
that it can use for memory allocation.

llvm-svn: 170798
 2012-12-20 22:54:05 +00:00
Jakob Stoklund Olesen 33f5d1492d Add an MF argument to MI::copyImplicitOps(). 
This function is often used to decorate dangling instructions, so a
context reference is required to allocate memory for the operands.

Also add a corresponding MachineInstrBuilder method.

Argyrios Kyrtzidis cbfd4d2483 Use some heuristics so that when a fixit removes a source range, we try 
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;

Nadav Rotem 2ababf68d7 LoopVectorize: Fix a bug in the scalarization of instructions. 
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.

This fixes External/SPEC/CINT95/099_go/099_go

Evan Cheng ddc0cb6dc5 On some ARM cpus, flags setting movs with shifter operand, i.e. lsl, lsr, asr, 
are more expensive than the non-flag setting variant. Teach thumb2 size
reduction pass to avoid generating them unless we are optimizing for size.

Eli Bendersky f658e92724 Add a largish auto-generated test for the aligned bundling feature, along with 
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.

Jakob Stoklund Olesen b109a7b430 Use MachineInstrBuilder in InstrEmitter. 
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.

James Molloy 4f6fb953a7 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).
