Boost C++ Libraries: Ticket #12804: Can't compiler IPC atomic_cas32<> on AIX.ppc with GCC

anonymous — Fri, 03 Feb 2017 09:53:46 GMT

Sorry for confusing, the issue is realated to IPC atomic. Here is a simple case that doesn't compile :

#include <boost/interprocess/detail/atomic.hpp>
#include <iostream>
int main()
{ boost::uint32_t o, i=0, w=1, c=2;
  o = boost::interprocess::ipcdetail::atomic_cas32(&i,w,c);
  std::cout << o << '\n';
}

and compile output :

$ /opt/gcc494/bin/g++ -maix64 -mminimal-toc -pthread  -B/opt/gcc494/bin/ -std=c++11 -fpermissive -O0 -g -Wall -Wextra -Wpedantic -Wno-unknown-pragmas -Wno-reorder -Wno-unused-parameter -Wno-unused-local-typedefs    -Wno-unused-variable -Wno-ignored-qualifiers -Wno-sign-compare -D_HAS_CPP0X=1 -I/opt/boost/boost_1_62_0/distro/aix.ppc64/include    -DWFMO -o minimal minimal.cpp

It seems that the problem is related with the assembler, the code assumes GNU as as those types of labels are typical.. I have no access to that platform so a patch from a user would be needed. Many atomic functions have a similar syntax.
