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.

bytes and not bytes.

Daniel Dunbar 75c12e1569 Remove unused AsmPrinter OptLevel argument, and propogate. 
- This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

Bill Wendling 31ceb1bcba Add an "alignment" field to the MachineFunction object. It makes more sense to 
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

This allows for future work that would allow for precise no-op placement and the
like.

Bob Wilson 5a495fea07 Provide InitializeAllTargets and InitializeNativeTarget functions in the 
C bindings.  Change all the backend "Initialize" functions to have C linkage.
Change the "llvm/Config/Targets.def" header to use C-style comments to avoid
compile warnings.

 2009-06-23 23:59:40 +00:00
Douglas Gregor 1b731d5dbe Introduce new headers whose inclusion forces linking and 
initialization of all targets (InitializeAllTargets.h) or assembler
printers (InitializeAllAsmPrinters.h). This is a step toward the
elimination of relinked object files, so that we can build normal
archives.

llvm-svn: 71975
 2009-05-17 10:15:22 +00:00
Bill Wendling f7b83c7ae7 Change MachineInstrBuilder::addReg() to take a flag instead of a list of 
booleans. This gives a better indication of what the "addReg()" is
doing. Remembering what all of those booleans mean isn't easy, especially if you
aren't spending all of your time in that code.

I took Jakob's suggestion and made it illegal to pass in "true" for the
flag. This should hopefully prevent any unintended misuse of this (by reverting
to the old way of using addReg()).
