[Openmp-dev] OMP Nodes Skipped over in AST for -ast-dump=json

Joshua Slagle via Openmp-dev openmp-dev at lists.llvm.org
Wed Feb 17 10:37:34 PST 2021 

Hi all,

I am attempting to print out the json format using clang's -ast-dump
option. I am additionally passing in the -fopenmp flag so that the command
looks like the following:
         clang -Xclang -ast-dump=json -Xpreprocessor -fopenmp

If the -ast-dump option is run WITHOUT the json specification, all works
well and all nodes are printed out (see ast_orig_temp.txt file). However,
when the -ast-dump is run WITH the json specification, OMP Clauses nodes
disappear (note that all other nodes I've checked *do* appear - see
ast_json_temp.json file).

Any input or insight into why this is happening? The end goal here is to
get the JSON representation of the Clang AST with OMP nodes, so if there is
another way to accomplish this that would be useful as well.

Thanks for all the help - Joshua
