Yep, good idea. I've just done that and I have:

1) -Q output now:

GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2

and

GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
options passed: ./xgcc -B. -Q -v /home/marxin/Programming/testcases/a.c -c -O2 -fverbose-asm -frecord-gcc-switches-format=driver -g -S

2) For -fverbose-asm:

# GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
# options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2

and

# GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
# options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2 -frecord-gcc-switches-file=/tmp/ccm3kL7d.cmdline

3) DWARF producer:

     <c>   DW_AT_producer    : (indirect string, offset: 0x97): GNU C17 11.0.0 20201204 (experimental) -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2

and

     <c>   DW_AT_producer    : (indirect string, offset: 0x27): GNU C17 11.0.0 20201204 (experimental) ./xgcc -B. -Q -v /home/marxin/Programming/testcases/a.c -c -O2 -fverbose-asm -frecord-gcc-switches-format=driver -g

Thoughts?
Thanks,
