Lang Hames 254bb971e0 Added a support for inserting new MBBs into the numbering. 
Unlike insertMachineInstrInMaps this does not guarantee live intervals will
remain correct. The caller will need to manually update intervals to account
for the changes made to the CFG.

Chris Lattner 88c185617c have the mc lowering process handle a few tail call forms, lowering them to 
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.

This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.

Bob Wilson 88a4e6dc0e Print "dregpair" NEON operands with a space between them, for readability and 
consistency with other instructions that have lists of register operands.

Dan Gohman 0b5aa1cdd3 Re-apply bottom-up fast-isel, with fixes. Be very careful to avoid emitting 
a DBG_VALUE after a terminator, or emitting any instructions before an EH_LABEL.

Bob Wilson 21eed476e8 Reenable DAG combining for vector shuffles. It looks like it was temporarily 
disabled and then never turned back on again.  Adjust some tests, one because
this change avoids an unnecessary instruction, and the other to make it
continue testing what it was intended to test.

Chris Lattner f469307c77 Change LEA to have 5 operands for its memory operand, just 
like all other instructions, even though a segment is not
allowed.  This resolves a bunch of gross hacks in the 
encoder and makes LEA more consistent with the rest of the
instruction set.

No functionality change.

Jakob Stoklund Olesen 823e90e12a Revert "Fix broken isCopy handling in TrimLiveIntervalToLastUse" 
This reverts commit 107921. It broke the clang self host.

llvm-svn: 107926
 2010-07-08 22:52:47 +00:00
Chris Lattner ec536276f0 add some long-overdue enums to refer to the parts of the 5-operand 
X86 memory operand.

Devang Patel 4c6bd6612f Relax assertion. In optimized code, it is possible that first instruction is coming from a inlined function. 
This fixes PR7596 .

Bill Wendling a992445ff2 Extension of r107506. Make sure that we don't mark a function as having a call 
if the inline ASM doesn't need a stack frame.

Chris Lattner 9f034c1e5d Rework segment prefix emission code to handle segments 
in memory operands at the same type as hard coded segments.
This fixes problems where we'd emit the segment override after
the REX prefix on instructions like:
mov %gs:(%rdi), %rax

This fixes rdar://8127102.  I have several cleanup patches coming
next.

llvm-svn: 107917
 2010-07-08 22:28:12 +00:00
Chris Lattner 1dd82c7dc2 introduce a new X86II::getMemoryOperandNo method, which 
returns the start of the memory operand for an instruction.

Introduce a new "X86AddrSegment" enum to reduce # magic numbers
referring to X86 memory operand layout.

Kevin Enderby ea9207cd7a Revert some unneeded parts of the change in r107886 for the 
.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.
