--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Replicating on x86_64-linux native yields (assuming empty.ld is an empty file):
g++ -o f.elf -T empty.ld -Wl,--gc-sections -O2 -save-temps obj.a
/usr/bin/ld: f.elf: not enough room for program headers, try linking with -N
/usr/bin/ld: final link failed: bad value
/usr/bin/ld: error: could not unlink output file
collect2: error: ld returned 1 exit status
not sure if it really makes sense to link using an empty linker script? Btw,
the removal error is probably from our debug copying magic:
31920 unlink("/tmp/ccXvUkmS") = 0
31920 unlink("f.elf.ltrans0.ltrans.o") = 0
31920 unlink("obj.a.debug.temp.o") = 0
31920 unlink("obj.a.debug.temp.o") = -1 ENOENT (No such file or directory)
31920 write(2, "/usr/bin/ld", 11) = 11
31920 write(2, ": error: could not unlink output"..., 38) = 38
which eventually ends up re-using the same temporary file multiple times
for each archieve member. Going to fix that.
