Bug ID: 16433
Summary: objdump -l reports wrong line numbers
Product: binutils
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: andi-bz at firstfloor dot org
objdump --version
GNU objdump (GNU Binutils; openSUSE 12.2) 2.22
Simple file:
1
2 volatile a = 10000, b = 100000, c;
3
4 __attribute__((noinline)) f2()
5 {
6 c = a / b;
7 }
Dumping the compiled simple file with objdump -Sl I get
00000000004004ec <f2>:
f2():
/home/ak/hle/tsrc/tcall.c:5
volatile a = 10000, b = 100000, c;
__attribute__((noinline)) f2()
{
4004ec: 55 push %rbp
4004ed: 48 89 e5 mov %rsp,%rbp
tcall.c:6
c = a / b;
4004f0: 8b 05 22 0b 20 00 mov 0x200b22(%rip),%eax #
601018 <a>
4004f6: 8b 15 20 0b 20 00 mov 0x200b20(%rip),%edx #
60101c <b>
4004fc: 89 55 fc mov %edx,-0x4(%rbp)
The problem is the tcall.c:5. The first empty line it shows is actually line 1,
not 5. Line 5 is the first executable statement. But when showing context it
should adjust the line nr to the context offset.
