Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Chris Lattner ca9d784bf1 change isGlobalStubReference to take target flags instead of a MachineOperand.

 2009-07-10 06:29:59 +00:00
Chris Lattner e6d259340e convert some late code (called by regalloc and code emission) 
to use isGlobalStubReference instead of GVRequiresExtraLoad
(which should really be part of isel).

Bill Wendling 2e09bd3d34 The MONITOR and MWAIT instructions have insufficient information for 
decoding. Essentially, they both map to the same column in the "opcode
extensions for one- and two-byte opcodes" table in the x86 manual. The RawFrm
complicates decoding this.

Instead, use opcode 0x01, prefix 0x01, and form MRM1r. Then have the code
emitter special case these, a la [SML]FENCE.

Dale Johannesen 72b6582c0f Use X86AddrNumOperands instead of magic constant one 
more place.  This fixes a bunch of x86-64 JIT regressions.
(Introduced when the value of the magic constant changed
in 68645.  At the time apparently nobody noticed; failures
were hidden in 70343-70439 by an unrelated bug, so showed
up again as "new" failures in 70440.)

Evan Cheng a35aed567a Revert part of 70929 that has to do with determining whether a SIB byte is needed. It causes a lot of x86_64 JIT failures.

Rafael Espindola 1edda06792 Reduce code duplication on the TLS implementation. 
This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

Dale Johannesen d4a5e8f74a In the absence of a linker to build the GOT, use the 32-bit

Dale Johannesen dafdbf77b3 Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

Dan Gohman fb19f9402b Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating 
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.
