[llvm-dev] How to read stack map

Hi all,

I was able to generate the Stack Map which is shown here
https://llvm.org/docs/StackMaps.html#stack-map-format. Now I want to read
those entries. What I did was, I manually change the .s file as shown below
(Added the *.globl __LLVM_StackMaps *manually). Then I can read the entries
using C code.

.globl __LLVM_StackMaps
__LLVM_StackMaps:
.byte 3
.byte 0
.short 0

I want to know, whether this is the correct approach. If not could you
please suggest me the correct approach?

Really appreciate your input on this.

Thank you,
Kavindu
