[llvm-dev] basic block labels in assembly (.s file)

[Vedant Kumar via llvm-dev]

Hi,

Does this need to be done in AsmPrinter?

Maybe it's possible to script this. In python, it could be:

with open(Path, 'rb') as F:
    re.subn(r'\.LBB_(\d+)', lambda M: '.MyLabel_' + M.group(1), F.read())

Is there a way that I can change the labels to other names, for example,  to ".MyLabel_number:" ? I think this should be related to AsmPrinter, but I cannot narrow down to certain specific source code.
