You're correct.
$ /opt/linaro/10.3.1/bin/../libexec/gcc/aarch64-none-elf/10.3.1/cc1 -E
-lang-asm -quiet -v -iprefix
/opt/linaro/10.3.1/bin/../lib/gcc/aarch64-none-elf/10.3.1/ src/boot.S
-mlittle-endian -mabi=lp64 -g -fworking-directory -fno-directives-only -o tmp.s
preprocesses the .S -> .s for as
$ /opt/linaro/10.2.1/bin/aarch64-none-elf-as --gdwarf2 -EL -mabi=lp64 -o boot.o
tmp.s
yields a .o file with debug info
$ /opt/linaro/10.3.1/bin/aarch64-none-elf-as --gdwarf2 -EL -mabi=lp64 -o boot.o
tmp.s
yields a .o file missing debug info
ergo it's not a gcc issue.
Thanks for helping to diagnose this so quickly.
