[Bug gas/3041] New: Bogus jump to weak symbol on m68k-unknown-netbsd
When assembled, a jump to weak symbol produces a jump to an invalid address. I found that problem on m68k-unknown-netbsd, but it may affect all m68k-*-aout targets. $ cat bug.s jmp mylabel nop .weak mylabel mylabel: nop $ as bug.s -o bug.o $ objdump -d bug.o bug.o: file format a.out-m68k-netbsd Disassembly of section .text: : 0: 4efa 000a jmp %pc@(c ) 4: 4e71nop 0006 : 6: 4e71nop The value of the jmp instruction is wrong : it should be %pc@(6 ) It might not be a problem, because there is a relocation. $ objdump -r bug.o bug.o: file format a.out-m68k-netbsd RELOCATION RECORDS FOR [.text]: OFFSET TYPE VALUE 0002 DISP16.text Here, it is clearly wrong. The relocation offset is good, but the value should be "mylabel" instead of ".text" After linking, there is no more relocation, but the value of the jump is still bad. The same problem was present in gas 2.14 for m68k-unknown-netbsd (already using BFD). The problem was not present in gas 2.14 for m68k-linux-aout (not using BFD) : $ objdump -d bug.o # binutils 2.14 m68k-linux-aout bug.o: file format a.out-zero-big Disassembly of section .text: : 0: 4efa 0004 jmp %pc@(6 ) 4: 4e71nop 0006 : 6: 4e71nop I think the above result is correct and the current version of gas for m68k- unknown-netbsd should behave like that. -- Summary: Bogus jump to weak symbol on m68k-unknown-netbsd Product: binutils Version: 2.18 (HEAD) Status: NEW Severity: normal Priority: P2 Component: gas AssignedTo: unassigned at sources dot redhat dot com ReportedBy: vincent dot riviere at freesbee dot fr CC: bug-binutils at gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: m68k-unknown-netbsd http://sourceware.org/bugzilla/show_bug.cgi?id=3041 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
