--- Comment #9 from Rainer Orth <ro at gcc dot gnu.org> 2013-02-14 10:11:11 UTC --- Created attachment 29448 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29448 proposed patch for __xnet_ socket functions This works fine in the 32-bit case, but for 64-bit (both sparc and x86) needed one further adjustment: the 64-bit tests were failing like this: amd64: --- FAIL: TestPassFD (0.09 seconds) :0: child process ReadAll: "", <nil>; want "Hello from child process!\n" FAIL FAIL: syscall sparcv9: --- FAIL: TestPassFD (0.28 seconds) passfd_test.go:102: child process ReadAll: "", <nil>; want "Hello from child process!\n" FAIL FAIL: syscall (Btw., need to check why filename and line number aren't detected on x86...) It turned out that as on Darwin, we always need 32-bit alignment. The attached patch does just that and allows the syscall to pass on both 32- and 64-bit Solaris/SPARC and x86.
