I don't know enough about AArch64 to assess here. Is the proposed
change below something we should take in tree? I'm happy to do
the mechanics of posting a patch (if Rob doesn't), but I don't
know enough to assess. Would such a patch be self contained? Or
is there other work needed?<br class="">

<div class="">I figured out the issue -- the AArch64 backend only emits
the stack map section if isOSBinFormateMachO() returns true --
see [1], lines 123 - 134. Moving the call to
serializeToStackMapSection() outside of the conditional fixes
the problem.<br class="">

<div class="">Hi everyone,<br class="">

</div>
I'm using LLVM's stack map intrinsic to store value
location information. I've got a pass that
automatically inserts the "llvm.experimental.stackmap"
intrinsic into the IR. On x86-64, an
".llvm_stackmaps" section is successfully emitted (I
can see the section & its contents in the
generated assembly). However I can't get the AArch64
backend to generate this section. On the website with
information about the intrinsic [1], it says that
AArch64 is supported. Is there a flag I need to add,
or is there something I need to enable when building
LLVM to get this support?<br class="">
