...he patchpoint and stackmap intrinsics into my pet project. In their current implementation (3.4 and trunk) the code to emit the additional section is only executed on Darwin. This is however quickly fixed: Add a ".llvm_stackmaps"-Section for ELF in MCObjectFileInfo and execute StackMaps::serializeToStackMapSection in X86AsmPrinter in the ELF-Branch. serializeToStackMapSection writes the information using MCStreamer, which seems to work properly. I'm using MCJIT with a custom memory manager to intercept the stackmap datasection, but no memory is allocated for this purpose. I'd be grateful, if someon...

Digging through the svn history it looks like the call to SM.serializeToStackMapSection() used to be unconditional but was put under the isOSBinFormateMachO() test in r206610.

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.

Hi everyone, 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
