ast parsed error

[pupiles]

define internal align 8 dereferenceable_or_null(16) i64* @"_ZNIterator$GT$4next17ha1b316511c33ec8fE"(i64* dereferenceable(16) %self) unnamed_addr #0 !dbg !0{
start:
  ret void
}

The codes above are ast parsed error when used asm.ParseFile because align 8 seems not supported when placed as the decorator of a function. Could you pass me some hints on that, really appreciate that.

Hi @pupiles,

This is probably related to #40? See #198 (comment) for an explanation of what is most likely causing the issue.

I wish we may find a good solution for this, but at least for now, I have not yet found one. If you know any way to solve #40, please let us know :D

Happy wishes from Sweden.

Cheers,
Robin

Hi @mewmew,

Thanks for your reply.

I wonder if there is a temporary solution to this issue，for the scenario where parsing the correct align position is not important.

Best Wishes,

Hi @mewmew,

Thanks for your reply.

Hi @pupiles, you're most welcome :)

I wonder if there is a temporary solution to this issue，for the scenario where parsing the correct align position is not important.

Here is possible and very crude work-around. It strips away align NN from function declarations and definitions, and call and invoke instructions.

go install -v github.com/mewkiz/cmd/sar@master

strip_ll.sh:

FILE=$1

sar -i 'call align [0-9]+ ' 'call ' $FILE
sar -i 'define align [0-9]+ ' 'define ' $FILE
sar -i 'declare align [0-9]+ ' 'declare ' $FILE
sar -i 'invoke align [0-9]+ ' 'invoke ' $FILE

Running strip_ll.sh heck.ll rewrites the heck.ll file so that it can be parsed with llir/llvm.

Parsing heck.ll (with align stripped) using l-tm of llir/llvm.

$ l-tm -v heck.ll

I'll close this as a duplicate of #40 for now. I do hope we find a good solution for #40 soon, as it comes up every now and then.

Happy coding!
