Bill Wendling 770d0f0700 Make sure we aren't deleting the landingpad instruction.
The landingpad instruction is required in the landing pad block. Because we're
not deleting terminating instructions, the invoke may still jump to here (see
Transforms/SCCP/2004-11-16-DeadInvoke.ll). Remove all uses of the landingpad
instruction, but keep it around until code-gen can remove the basic block.

Owen Anderson 939cd21248 When performing instruction selection for LDR_PRE_IMM/LDRB_PRE_IMM, we still need to preserve the sign of the index. This fixes miscompilations of Quicksort in the nightly testsuite, and hopefully others as well.

Jim Grosbach 6a69d6902f Run the Thumb1 parser tests in Thumb2 mode, as well.
Thumb2 is a superset of Thumb1, so all of the encodings should still work.

2011-08-31 19:50:28 +00:00
Jim Grosbach cfa9421e16 Remove FIXME. Thumb2 MOV instruction will use separate custom tricks.
When we want encoding T3 (the wide encoding), we can explicitly check for
that and twiddle the CanAcceptCarrySet accordingly. For now, just correctly
handle encodings T1 and T2 when in Thumb2 mode.

Eli Friedman e839ecb70b Fill in type legalization for MERGE_VALUES in all the various cases. Patch by Micah Villmow. (No testcase because the issue only showed up in an out-of-tree backend.)

Jim Grosbach c61fc8f301 tBcc is OK to be predicated in Thumb2 outside of IT blocks (obviously).

same.

Jim Grosbach 6d606fbe14 Tweak Thumb1 ADD encoding selection a bit.
When the destination register of an add immediate instruction is
explicitly specified, encoding T1 is preferred, else encoding T2 is
preferred.

Jakob Stoklund Olesen cd893390f5 Put VMOVS widening under a command line option, off by default.
It appears that our use of the imp-use and imp-def flags with
sub-registers is not yet robust enough to support this.

The failing test case is complicated, I am working on a reduction.

Rafael Espindola a45c20b049 Remove the old tail duplication pass. It is not used and is unable to update
ssa, so it has to be run really early in the pipeline. Any replacement
should probably use the SSAUpdater.

Rafael Espindola 94d3253626 Adds support for variable sized allocas. For a variable sized alloca,
code is inserted to first check if the current stacklet has enough
space. If so, space is allocated by simply decrementing the stack
pointer. Otherwise a runtime routine (__morestack_allocate_stack_space
in libgcc) is called which allocates the required memory from the
heap.

Rafael Espindola 3353017668 Adds a SelectionDAG node X86SegAlloca which will be custom lowered
from DYNAMIC_STACKALLOC.

Two new pseudo instructions (SEG_ALLOCA_32 and SEG_ALLOCA_64) which
will match X86SegAlloca (based on word size) are also added.  They
will be custom emitted to inject the actual stack handling code.

Patch by Sanjoy Das.
