[Bug gas/3136] Implement .bss for ELF
https://sourceware.org/bugzilla/show_bug.cgi?id=3136 Pete Moore changed: What|Removed |Added CC||petemoore at gmx dot net --- Comment #1 from Pete Moore --- This looks similar to bug 27047 for h8300-elf instead of z80-unknown-elf, so maybe needs a similar patch? However, this bug is 15 years old so maybe the issue is already resolved? -- You are receiving this mail because: You are on the CC list for the bug.
