Evan Cheng 0cbe920d7c Oops. Debugging code shouldn't have been checked in.

Ted Kremenek 1172416d65 Removed debug #define that was accidentally checked in while debugging 
the deserializer.

Fixed assertion when "stream jumping" in the deserializer to properly function
when we have reached the end of the stream.

Anton Korobeynikov 2c6387803e Fix PIC jump table codegen on x86-32/linux. In fact, such thing should be applied 
to all targets uses GOT-relative offsets for PIC (Alpha?)

Duncan Sands e2287ed552 Eliminate the recently introduced CCAssignToStackABISizeAlign 
in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values.  This seems a neater solution.
It is safe since no legal value type has size 0.

Ted Kremenek 545f7e39e1 Added two new overloaded versions of BatchEmitOwnedPtrs and 
BatchReadOwnedPtrs.

Evan Cheng 7f02cfa599 Clean up sub-register implementation by moving subReg information back to 
MachineOperand auxInfo. Previous clunky implementation uses an external map
to track sub-register uses. That works because register allocator uses
a new virtual register for each spilled use. With interval splitting (coming
soon), we may have multiple uses of the same register some of which are
of using different sub-registers from others. It's too fragile to constantly
update the information.

Nick Lewycky c6243020a6 Allow the block extractor take to take a list of basic blocks to not extract 
from a file containing Function/BasicBlock pairings. This is not safe against
anonymous or abnormally-named Funcs or BBs.

Make bugpoint use this interface to pass the BBs list to the child bugpoint.

Dale Johannesen 7a7085f6d3 Add parameter to getDwarfRegNum to permit targets 
to use different mappings for EH and debug info;
no functional change yet.
Fix warning in X86CodeEmitter.

Chris Lattner 61ce4dff7a Implement PR1786 by iterating between dead cycle elimination 
and simplifycfg in the rare cases when it is needed.

llvm-svn: 44044
 2007-11-13 07:32:38 +00:00
Bill Wendling f359fed9f9 Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack 
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).

This can only result in tears...

Anton Korobeynikov bfb139ec93 Completely forgot, that we have some debug information emission on PPC. This should fix 
some regressions on ppc nightly tests.

Bruno Cardoso Lopes b439132d16 Added JumpTable support 
Fixed some AsmPrinter issues
Added GLOBAL_OFFSET_TABLE Node handle.

 2007-11-12 19:49:57 +00:00
Ted Kremenek e33ba16368 Added versions of ReadPtr that takes an explicit SerializedPtrID. This allows 
clients of the Deserializer to read the pointer ID before they are ready
to deserialize the object (which can mean registering a pointer reference
with the backpatcher).

Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference).  This is to accommodate a future
revision of SerializedPtrID where it may be much fatter than an unsigned
integer.

Owen Anderson 933b5b7e62 Add a flag for indirect branch instructions. 
Target maintainers: please check that the instructions for your target are correctly marked.

 2007-11-12 06:35:08 +00:00
Owen Anderson a1cd45213d As Chris and Evan pointed out, BreakCriticalMachineEdges doesn't really need 
to be a pass of its own.  Instead, move it out into a helper method.

Anton Korobeynikov 4edfea438a Use TableGen to emit information for dwarf register numbers. 
This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.
Please check another subtargets if possible,

Dale Johannesen b988e7e8cd Add CCAssignToStackABISizeAlign for convenience in 
dealing with types whose size & alignment are
different on different subtargets.  Use it for x86 f80.

llvm-svn: 43978
 2007-11-10 10:48:01 +00:00
Ted Kremenek 55e30be8ec Added "random access" to the Deserializer to allow a client to jump to any 
serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

Duncan Sands e7a9ac929f Fix some load/store logic that would be wrong for 
apints on big-endian machines if the bitwidth is
not a multiple of 8.  Introduce a new helper,
MVT::getStoreSizeInBits, and use it.
