Why llvm values can't start with %1?

Project Infrastructure LLVM Dev List Archives

After I manually modified .ll file deleting %0 I am getting this error from llvm-as:

lvm-as: my.ll:43:3: error: instruction expected to be numbered '%0'
  %1 = tail call noalias i8* @malloc(i32 8) nounwind ; <i8*> [#uses=1]
  ^

So now I have to also rename all other %<NUM> variables? Why llvm is so strict with naming? I think it should just accept whatever names are there as long as they make a valid .ll file.

Whoops! Forgot to send it to the list!

Hi Yuri

If you want to, you can name the registers with %r1 or some other

string with a number after it. My guess about the reason it's so strict
with the numbered SSA registers is that it automatically numbers unnamed
registers internally without registering a name in memory. If you do give
it a name, it will take more memory but will be more flexible in the conventions
used to name the registers.
