objdump --disassemble=sym peculiarities
Given this testcase:
.text
mov $x1,%eax
f1:
mov $f1,%eax
.type f1,@function
.size f1,.-f1
mov $x2,%eax
f2:
mov $f2,%eax
.type f2,@function
.size f2,.-f2+0x1000 #bad size
objdump --reloc --disassemble=f1 prints
00000000 <f1-0x5>:
0: b8 00 00 00 00 mov $0x0,%eax
and objdump --reloc --disassemble=f2 prints
0000000f <f2>:
f: b8 0f 00 00 00 mov $0xf,%eax
10: R_386_32 .text
It seems for f1 we get the insn before f1 and no reloc whereas, post
159daa36fa, f2 is disassembled correctly. Some analysis says that
find_symbol_for_address may return a symbol past the current address,
and reloc skipping is broken. Fix both of these problems.
* objdump.c (disassemble_jumps, disassemble_bytes): Replace
relppp with relpp, ie. don't update caller's rel_pp. Adjust
calls.
(disassemble_section): Skip over relocs inside loop rather
than before loop. Revert 7e538762c2c1. If given a symbol,
don't start disassembling until its address is reached.
Correct end of function calculation.
