* Final step in the metadata API restructuring: move the Chris Lattner2009-12-291-4/+1
| | | | | | | | getMDKindID/getMDKindNames methods to LLVMContext (and add convenience methods to Module), eliminating MetadataContext. Move the state that it maintains out to LLVMContext. llvm-svn: 92259
* This is a major cleanup of the instruction metadata interfaces thatChris Lattner2009-12-281-21/+18
| | | | | | | | | | | | | | | | | | | | | | I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. llvm-svn: 92235
* rename getHandlerNames to getMDKindNames, simplify its interfaceChris Lattner2009-12-281-21/+16
| | | | | | and simplify all the clients that use it. llvm-svn: 92224

* Revert 85678/85680. The decision is to stay with the current form of Chris Lattner2009-11-011-2/+1
| | | | | | | indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it for simplicity. llvm-svn: 85699
* Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner2009-10-311-1/+2
| | | | | | | | | | | | block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). llvm-svn: 85678
* bitcode writer support for blockaddress.Chris Lattner2009-10-281-0/+7
| | | | llvm-svn: 85376
* Previously, all operands to Constant were themselves constant.Chris Lattner2009-10-281-3/+4
| | | | | | | | | In the new world order, BlockAddress can have a BasicBlock operand. This doesn't permute much, because if you have a ConstantExpr (or anything more specific than Constant) we still know the operand has to be a Constant. llvm-svn: 85375
* rename indbr -> indirectbr to appease the residents of #llvm.Chris Lattner2009-10-281-2/+2
