Summary: AVR: disassemble START,END dumps data memory (SRAM)
Product: gdb
Version: 7.2
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: tdep
AssignedTo: unassigned@sourceware.org
ReportedBy: news@schildmann.info
(gdb) disassemble 0x00000718, 0x00000724
Dump of assembler code from 0x800718 to 0x800724:
0x00800718: nop
0x0080071a: nop
0x0080071c: nop
0x0080071e: nop
0x00800720: nop
0x00800722: nop
End of assembler dump.
Without arguments the command works as expected:
(gdb) disassemble
Dump of assembler code for function tasks__cyclic_led_0B:
0x00000718 <+0>: push r29
0x0000071a <+2>: push r28
0x0000071c <+4>: in r28, 0x3d ; 61
0x0000071e <+6>: in r29, 0x3e ; 62
0x00000720 <+8>: sbiw r28, 0x07 ; 7
0x00000722 <+10>: in r0, 0x3f ; 63
0x00000724 <+12>: cli

0x00000728 <+16>: out 0x3f, r0 ; 63
0x0000072a <+18>: out 0x3d, r28 ; 61

End of assembler dump.

--- Comment #1 from Nav <nav at bloom dot oscillate.io> ---
Created attachment 13683
--> https://sourceware.org/bugzilla/attachment.cgi?id=13683&action=edit
screenshot of failed attempt to reproduce bug
This is a result of 13519
(https://sourceware.org/bugzilla/show_bug.cgi?id=13519), which has since been
resolved. I cannot replicate this issue on GDB 11.0.50 (see attached
screenshot). GDB no longer applies the SRAM offset when reading program memory
for disassemble operations.
I believe this has been fixed since version 10.
