I realized I still managed to mess up some WS. I have attached a patch that is the same, except fixes the WS issue
underneath.
Regards, Petter

Subject: [PATCH 1/2] libgccjit: Generate debug info for variables
Finalize declares via available helpers after location is set. Set
TYPE_NAME of primitives and friends to "int" etc. Debug info is now
set properly for variables.
Signed-off-by:
2021-09-05 Petter Tomner <tomner@kth.se>
gcc/jit/
* jit-playback.c: Moved global var processing to after loc handling.
Setting TYPE_NAME for fundamental types.
Using common functions for finalizing globals.
* jit-playback.h: New method init_types().
Changed get_tree_node_for_type() to method.
gcc/testsuite/jit.dg/
* test-error-array-bounds.c: Array is not unsigned
