No, that should work.

And you should add -Wa,-l, -Wa,--all-relocs, etc.

What do these do? (Are they included in -Wall? Because when I added these two, it didn't change my program size, which suggests to me that it didn't do anything. Of course, I know that isn't always true, but it seems suspicious...)

According to the docs, -Wall simply allows warnings. The W stands for WARN. All -W or -w switches control warnings.

#33: -Wa,-l != -Wall...

#32: unless you already added those options to the assembler options, they usually improve things. Maybe your program already uses -mpcrel or -freg-relative-an ?
