I'm trying to formulate a bug report for tools used to examine/
process debug output.
looking specifically at the _debug_frame.
for this source:
---
int testfunc(void)
{
int i;
i = 1;
return i;
}
===
using -save-temps -dA -g -O0 -fverbose-asm (-gstrict-dwarf, on 4.5)
comparing the output of gcc-4-4 and trunk.
The main difference (and the area causing the tool to barf) is that
the FDE on 4.5 has some extra information not present in 4.4
.byte 0x4 # DW_CFA_advance_loc4
.set L$set$6,LCFI3-LCFI1
.long L$set$6
.byte 0xc5 # DW_CFA_restore, column 0x5
.byte 0xc # DW_CFA_def_cfa
.byte 0x4 # uleb128 0x4
.byte 0x4 # uleb128 0x4
whilst, with the aid of the dwarf3 spec, I can see that this is
syntactically correct (and confirm that the object file contains the
correct output).
I can't (at the moment) determine if it's logically correct.
What is the purpose of the addition?
(complete .s files attached)
TIA,
Iain
