These were pretty straightforward instructions, with some assembly support
required for HLT.
The ARM assembler is keen to split the instruction mnemonic into a
(non-existent) 'H' instruction with the LT condition code. An exception for
HLT is needed.
HLT follows the same rules as BKPT when in IT blocks, so the special BKPT
hadling code has been adapted to handle HLT also.
Regression tests added including diagnostic tests for out of range immediates
and illegal condition codes, as well as negative tests for pre-ARMv8.

This improves code generation for jump tables by avoiding the emission of "mov pc, lr" which could fool the processor into believing this is a return from a function causing mispredicts. The code generation logic for jump tables uses ADR to materialize the address of the jump target.

In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.
This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.

This reverts commit r189886.
I found a corner case where this optimization is not valid:
Say we have a "linkonce_odr unnamed_addr" in two translation units:
* In TU 1 this optimization kicks in and makes it hidden.
* In TU 2 it gets const merged with a constant that is *not* unnamed_addr,
resulting in a non unnamed_addr constant with default visibility.
* The static linker rules for combining visibility them produce a hidden
symbol, which is incorrect from the point of view of the non unnamed_addr
constant.
The one place we can do this is when we know that the symbol is not used from
another TU in the same shared object, i.e., during LTO. I will move it there.

This was regression from r134829. When linking we have to be conservative. If
one of the symbols has a significant address, then the result should have it
too.

"(icmp op i8 A, B)" is equivalent to "(icmp op i8 (A & 0xff), B)" as a

Even in cases which aren't universally optimisable like "(A & B) != 0 && (A &

Original message:
If a constant or a function has linkonce_odr linkage and unnamed_addr, mark
hidden. Being linkonce_odr guarantees that it is available in every dso that
needs it. Being a constant/function with unnamed_addr guarantees that the
copies don't have to be merged.

The reason that I am turning off this optimization is that there is an
additional case where a block can escape that has come up. Specifically, this
occurs when a block is used in a scope outside of its current scope.
This can cause a captured retainable object pointer whose life is preserved by
the objc_retainBlock to be deallocated before the block is invoked.
An example of the code needed to trigger the bug is:
----
\#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
void (^somethingToDoLater)();
{
NSObject *obj = [NSObject new];
somethingToDoLater = ^{
[obj self]; // Crashes here
};
}
NSLog(@"test.");
somethingToDoLater();
return 0;
}
----
In the next commit, I remove all the dead code that results from this.
Once I put in the fixing commit I will bring back the tests that I deleted in

has hard float, when you compile the mips32 code you have to make sure
that it knows to compile any mips32 routines as hard float. I need to clean
up the way mips16 hard float is specified but I need to first think through
all the details. Mips16 always has a form of soft float, the difference being
whether the underlying hardware has floating point. So it's not really
necessary to pass the -soft-float to llvm since soft-float is always true
for mips16 by virtue of the fact that it will not register floating point
registers. By using this fact, I can simplify the way this is all handled.

This is the next big chunk of fast-isel code. The primary purpose is
to implement selection of loads and stores, but there is a lot of
drag-along to support this. The common code to analyze addresses for
both loads and stores is substantial. It's also necessary to add the
materialization code for global values.
Related to load-store processing is the code to fold loads into
integer extends, since otherwise we generate lots of redundant
instructions. We also need to add some overrides to some FastEmit
routines to ensure we don't assign GPR 0 to a virtual register when
this would change the meaning of an instruction.
I added handling selection of a few binary arithmetic instructions, to
enable committing some test cases I wrote a while back.
Finally, ap couple of miscellaneous changes:
* I cleaned up some poor style from a previous patch in

When unrolling is disabled in the pass manager, the loop vectorizer should also
not unroll loops. This will allow the -fno-unroll-loops option in Clang to
behave as expected (even for vectorizable loops). The loop vectorizer's
-force-vector-unroll option will (continue to) override the pass-manager
setting (including -force-vector-unroll=0 to force use of the internal
auto-selection logic).
In order to test this, I added a flag to opt (-disable-loop-unrolling) to force
disable unrolling through opt (the analog of -fno-unroll-loops in Clang). Also,
this fixes a small bug in opt where the loop vectorizer was enabled only after
the pass manager populated the queue of passes (the global_alias.ll test needed
a slight update to the RUN line as a result of this fix).

with a debug build) with this buggy .indirect_symbol directive usage:
% cat test.s
x: .indirect_symbol _y
The assertion is because it is trying to get the symbol index for the
symbol _y when it is writing out the indirect symbol table. This line of
code in MachObjectWriter::WriteObject() :
Write32(Asm.getSymbolData(*it->Symbol).getIndex());
And while there is a symbol _y it does not have any getSymbolData set which
is only done in MachObjectWriter::BindIndirectSymbols() for pointer sections
or stub sections. I added a check and an error in there to catch this in case
something slips through.
But to get a better error the parser should detect when a .indirect_symbol
directive is used and it is not in a pointer section or stub section. To make
that work I moved the handling of the indirect symbol out of the target
independent AsmParser code into the DarwinAsmParser code that can check
for the proper Mach-O section types.

Lengths above that threshold use a loop to handle X*256 bytes followed

Because the same tablegen classes are used to define MVC and CLC,

Get the register class right for the TST instruction. This keeps the
machine verifier happy, enabling us to turn it on for another test.

Constant pool and global value reference instructions need more
restricted register classes than plain GPR.

Incremental improvement to fast-isel for PPC64. This allows us to
select on ret, sext, and zext. Filling in sext/zext improves some of
the existing logic in handling compare-immediates that needed extends.
A simplified return convention for fast-isel is also added to the
PPC64 calling conventions. All call/return processing for DAG
selection is handled with custom code, so there isn't an existing CC
to rely on here. The include of PPCGenCallingConv.inc causes compiler
warnings due to the 32-bit calling conventions that are not used, so
the dummy function "usePPC32CCs()" is added here to silence those.
Test cases for the return and extend logic are added.

If we have a binary operation like ISD:ADD, we can set the result type
equal to the result type of one of its operands rather than using
TargetLowering::getPointerTy().
Also, any use of DAG.getIntPtrConstant(C) as an operand for a binary
operation can be replaced with:
DAG.getConstant(C, OtherOperand.getValueType());

This adds minimal support to the SelectionDAG for handling address spaces
with different pointer sizes. The SelectionDAG should now correctly
lower pointer function arguments to the correct size as well as generate
the correct code when lowering getelementptr.
This patch also updates the R600 DataLayout to use 32-bit pointers for
the local address space.
v2:
- Add more helper functions to TargetLoweringBase
- Use CHECK-LABEL for tests

First chunk of actual fast-isel selection code. This handles direct
and indirect branches, as well as feeding compares for direct
branches. PPCFastISel::PPCEmitIntExt() is just roughed in and will be
expanded in a future patch. This also corrects a problem with
selection for constant pool entries in JIT mode or with small code
model.

-Assembly parser now properly check the size of the memory operation specified in intel syntax. So 'mov word ptr [5], al' is no longer accepted.
-x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size.
-Intel syntax printing prints the ptr size and places brackets around the address immediate.
Known remaining issues with these instructions:
-Segment override prefix is not supported. PR16962 and PR16961.
-Immediate size should be changed by address size prefix.

I need to add the rest of these to the list or else to delay putting
out the actual stub until later in code generation when I know if
the external function ever got emitted
Resubmit this patch. The target triple needs to be added to the test so that
clang does not tell the backend the wrong target when the host is BSD. There
is a clang bug in here somewhere that I need to track down. At Mips this
has been filed internally as a bug.
