Hello Nick,
Thank you for the quick response! I tested the patch, but unfortunately the DIE
still has the LSB bit set in DW_AT_low_pc, and GDB still fails:
<1><1fe>: Abbrev Number: 2 (DW_TAG_subprogram)
<1ff> DW_AT_name : (strp) (offset: 0x47a): main
<203> DW_AT_external : (flag_present) 1
<203> DW_AT_type : (ref_udata) <0x209>
<204> DW_AT_low_pc : (addr) 0x10517
<208> DW_AT_high_pc : (udata) 12
(gdb) x /i main+8
0x1051f <main+7>: b.n 0x10c62
(gdb) FAIL: gdb.arch/pr25124.exp: disassemble thumb instruction (1st try)
Without the patch, DW_AT_low_pc had value 0x10519:
