Bug ID: 22097
Summary: 16bit code misassembled by llvm-mc
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86

test case
The attached testcase (using .code16) is misassembled by llvm-mc as witnessed
by the changed offsets of symbols. ie.
ref11-amd64 i386$ $CC -no-integrated-as -c -m32 boot1.s && objdump -d boot1.o |
grep 'main.*>:'
0000003e <main>:
00000063 <main.1>:
00000068 <main.2>:
00000075 <main.3>:
00000087 <main.4>:
00000089 <main.5>:
ref11-amd64 i386$ $CC -integrated-as -c -m32 boot1.s && objdump -d boot1.o |
grep 'main.*>:'
0000003e <main>:
00000065 <main.1>:
0000006a <main.2>:
0000007b <main.3>:
00000090 <main.4>:
00000092 <main.5>:
Note that "main" is at correct offset but main.1 is 2 bytes off and it keeps
increasing.
