Description
Some ranges of assembly instructions are still omitted from the QtCreator disassembly (Operate by Instruction) window. This happened with 3.0.0 and happens with 3.1.0. I am running the 64-bit QtCreator and debugging 32-bit programs. I have cleared out my .gdbinit file to avoid complications from it, but the problem persists. I can't figure out what the pattern is – some instructions appear, others don't. The omitted instructions seem to occur in blocks.
Here is some disassembly from the command window:
>~" 0xf6b1eff4 <+36>:\tlea 0x0(%esi,%eiz,1),%esi\n"
>~" 0xf6b1eff8 <+40>:\tmov (%edi),%eax\n"
>~" 0xf6b1effa <+42>:\tmov 0x11c(%esi),%edx\n"
>~" 0xf6b1f000 <+48>:\tmov (%eax,%ebx,4),%eax\n"
>~" 0xf6b1f003 <+51>:\tadd $0x1,%ebx\n"
>~" 0xf6b1f006 <+54>:\tmov 0x54(%edx),%edx\n"
>~" 0xf6b1f009 <+57>:\tmovswl 0x14(%eax),%ecx\n"
>~" 0xf6b1f00d <+61>:\tmov (%edx,%ecx,4),%edx\n"
>~" 0xf6b1f010 <+64>:\tmov 0x4c(%edx),%edx\n"
>~" 0xf6b1f013 <+67>:\tmov %eax,0x4(%esp)\n"
>~" 0xf6b1f017 <+71>:\tmov %esi,(%esp)\n"
>~" 0xf6b1f01a <+74>:\tand $0xfffff,%edx\n"
>~" 0xf6b1f020 <+80>:\tadd 0x10(%ebp),%edx\n"
>~" 0xf6b1f023 <+83>:\tmov %edx,0x8(%esp)\n"
>~" 0xf6b1f027 <+87>:\tmov (%esi),%eax\n"
>~" 0xf6b1f029 <+89>:\tcall *(%eax)\n"
>~" 0xf6b1f02b <+91>:\tcmp 0xc(%edi),%ebx\n"
>~" 0xf6b1f02e <+94>:\tjl 0xf6b1eff8 <CPropOffsetStack::RecurseAndCallProxies(CSendNode*, unsigned char*)+40>\n"
Here is what the Operate by Instruction window shows:
0xf6b1eff4 <+0x0024> lea 0x0(%esi,%eiz,1),%esi
0xf6b1f003 <+0x0033> add $0x1,%ebx
0xf6b1f02b <+0x005b> cmp 0xc(%edi),%ebx
0xf6b1f02e <+0x005e> jl 0xf6b1eff8 <CPropOffsetStack::RecurseAndCallProxies(CSendNode*, unsigned char*)+40>
Here's the raw memory for the entire function:
0xf6b1efd0: 55 89 e5 57 56 53 83 ec 1c 8b 7d 0c 8b 75 08 8b 55 10 0f b7 47 22 89 54 86 08 8b 47 0c 85 c0 7e

0xf6b1f010: 8b 52 4c 89 44 24 04 89 34 24 81 e2 ff ff 0f 00 03 55 10 89 54 24 08 8b 06 ff 10 3b 5f 0c 7c c8
