[llvm-commits] PATCH: BasicBlock metadata

[Ralf Karrenberg]

Hi,

please find attached a patch that adds metadata functionality to BasicBlocks.
It should include all that is required for full support via BitcodeReader/Writer, AsmParser/Writer, etc.

Essentially, the patch mimics behaviour of metadata that is attached to instructions.

The chosen syntax for block metadata is as follows:

entry:
    %property1 !0, %property2 !1
  %x = fadd float %a, %b
  ret float %x

Looking forward to getting feedback on the patch :).

Cheers,
Ralf
