Bug ID: 26001
Summary: [clang-cl] error: "asm operand has incomplete type" on
boost::atomic
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: heavenandhell...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Clang is failing to compile this:
#include <boost/atomic.hpp>
int main() {
boost::atomic<boost::int64_t> counter;
counter.store(0, boost::memory_order_relaxed);
return 0;
}
This is one of the errors i'm getting:
../boost_1_60_0\boost/atomic/detail/ops_msvc_x86.hpp(640,26) : error: asm
operand has incomplete type 'volatile storage_type *' (aka 'volatile typename
make_storage_type<8U, Signed>::type *')
mov edx, p
^
The snippet is a reduced test case i extracted from a library. It can be built
with the following command (there's no need to build boost):
clang-cl Tmp.cpp -Ic:\boost_1_60_0\
Note, the error only happen with 64 bit integers, if i change the type to
int32_t or long, there's no error.
