Evan Cheng d985d66781 Allow patterns to refer to physical registers that belong to multiple 
register classes.

Reid Spencer 540c1b95f1 Make sure that $(CXX.Flags) is passed to the linker so that the same options 
with which source is compiled are used when linking. This matters when a
project is using the LLVM makefiles and overrides CXXFLAGS to specify new
flags to use.

Chris Lattner 3d82699605 Add a chain to FORMAL_ARGUMENTS. This is a minimal port of the X86 backend, 
it doesn't currently use/maintain the chain properly.  Also, make the
X86ISelLowering.cpp file 80-col clean.

Vladimir Prus 788db2c812 Replace "../whatever.td" with "whatever.td", so that out-of-tree backends 
can just add lib/Target to TableGen includes.

Reid Spencer 1053658517 When linking, make sure the project libraries are linked before the LLVM 
libraries. This ensures that the project's libraries (which most likely
depend on LLVM libraries) come first on the command line and can thus be
resolved by the LLVM libraries that appear later.

Chris Lattner 957cb6733a Move function-live-in-handling code from the sdisel code to the scheduler. 
This code should be emitted after legalize, so it can't be in sdisel.

Note that the EmitFunctionEntryCode hook should be updated to operate on the
DAG.  The X86 backend is the only one currently using this hook.

for each argument.

Add an additional catch block to ensure that this function can't throw any
exceptions, even one's we're not expecting.

Reid Spencer 3d01718c70 Upgrade in preparation for doxygen 1.4.4. The config file format changed, 
there are new/different css styles to support, and the footer was woefully
out of date.

Chris Lattner 63539389ca LoadLibraryPermanently can theoretically throw an exception. Do not propagate 
it out of 'ExecutionEngine::create'.  This fixes a problem reported by coverity.

Chris Lattner f64397ba1a This function is not documented as throwing an exception and callers don't 
handle it.  Just silently fail.

Chris Lattner f98ede25bb This is a proper fix for the compiler warning. A termination condition is 
not needed, as it can never be reached: an edge must exist.

Reid Spencer 70de606bb9 For PR741:

Chris Lattner 3987a8532d Add/Sub/Mul are safe to promote here as well. Incrementing a single-bit 
bitfield now gives this code:

_plus:
        lwz r2, 0(r3)
        rlwimi r2, r2, 0, 1, 31
        xoris r2, r2, 32768
        stw r2, 0(r3)
        blr

instead of this:

_plus:
        lwz r2, 0(r3)
        srwi r4, r2, 31
        slwi r4, r4, 31
        addis r4, r4, -32768
        rlwimi r2, r4, 0, 0, 0
        stw r2, 0(r3)
        blr

this can obviously still be improved.
