Bug ID: 18338
Summary: Local label in inline assembly
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
The following inline assembly can be complied by MSVC 2010, but not by Clang.
bool asm_inline()
{
_asm {
jmp done;
done:
}
}
bool asm_inline_1()
{
_asm {
jmp done;
done:
}
}
Clang produces error:
Debug\test.asm:45:2: error: invalid symbol redefinition
done:
^
Apprantly Clang does't treat the label "done" as local lable. Here's the
assembly code generated by Clang:
"?asm_inline@@YA_NXZ": # @"\01?asm_inline@@YA_NXZ"
# BB#0: # %entry
pushl %ebp
movl %esp, %ebp
pushl %esi
pushl %eax
movl %esp, %esi
#APP
.intel_syntax
jmp done
done:
.att_syntax
#NO_APP
ud2
.def "?asm_inline_1@@YA_NXZ";
.scl 2;
.type 32;
.endef
.globl "?asm_inline_1@@YA_NXZ"
.align 16, 0x90
"?asm_inline_1@@YA_NXZ": # @"\01?asm_inline_1@@YA_NXZ"
# BB#0: # %entry
pushl %ebp
movl %esp, %ebp
pushl %esi
pushl %eax
movl %esp, %esi
#APP
.intel_syntax
jmp done
done:
.att_syntax
#NO_APP
ud2
.def _main;
.scl 2;
.type 32;
.endef
.globl _main
.align 16, 0x90
