Created this patch to add GCC version to the graph data
for the options:
-fdump-rtl-all-graph
-fdump-tree-all-graph
-fdump-ipq-all-graph
-fcallgraph-info
-fdump-analyzer-callgraph
-fdump-analyzer-exploded-graph
-fdump-analyzer-supergraph
-fdump-analyzer-state-purge
-fdump-analyzer-feasibility
using gcc git version 4 july 2021
git describe

gcc --version
gcc (GCC) 12.0.0 20210704 (experimental)

The start of the gcc -fcallgraph-info output now looks like this:
/* callgraph generated by GNU GCC Compiler -fcallgraph-info option version
* GNU C17 (GCC) version 12.0.0 20210704 (experimental)
(x86_64-pc-linux-gnu)
* compiled by GNU C version 12.0.0 20210704 (experimental), GMP version
6.2.0, MPFR version 4.0.2, MPC version 1.1.0, isl version none
* GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
*/
graph: { title: "foo.c"
node: { title: "hello_GCC" label: "hello_GCC\nfoo.c:3:6" }
...
}
There are more routines in GCC generating graph data
but do not know the options how to use it.
