BOOST_NOINLINE NVCC in __HOST__

[a.huebl@…]

I am compiling with gcc 4.6.2 and CUDA (nvcc 5.0, V0.2.1221) causing an:

include/boost/assert.hpp:102:47: Error: »noinline« was not defined in
this scope

if I do not override with

-DBOOST_NOINLINE='__attribute__ ((noinline))'

The problem resides at boost/config/suffix.hpp.

Affected files (using):

• include/boost/assert.hpp
• include/boost/log/detail/spin_mutex.hpp

That's strange, since it works in code not included in __host__ calls.

Example to reproduce the problem:

#include <stdlib.h>     /* srand, rand */
#include <time.h>       /* time */

#include <boost/assert.hpp>

__host__ void abc()
{
   int i = 3;
   BOOST_ASSERT_MSG( i%2 == 0, "MYMESSAGE" );
}

int main()
{
  srand (time(NULL));
  int i = rand() % 10 + 1;

  BOOST_ASSERT_MSG( i%2 == 0, "MYMESSAGE" );

  return 0;
}

Compile with:

• nvcc main.cu
• nvcc -DBOOST_NOINLINE='__attribute__ ((noinline))' main.cu

References:

• ​gcc 3.1.1 attributes (without the __)
• ​gcc 4.6.2 attributes (allowing the __)
• ​boost 1.54: __attribute__((__visibility__("default")))
• ​boost 1.55: BOOST_NOINLINE in assert.hpp

patch for nvcc

[a.huebl@…]

the patch should work for boost/config/suffix.hpp 806db13db73d2773278f31bf2f96bcb8d3fe9bcf

Fixed in Git develop.

Note: The latest CUDA release (version 6.5) fixed that problem in nvcc, too.
