* [Bug c++/19450] New: __thread static class members @ 2005-01-14 19:14 gcc-bugzilla at gcc dot gnu dot org 2005-01-14 19:31 ` [Bug c++/19450] " pinskia at gcc dot gnu dot org 2005-02-13 14:25 ` pinskia at gcc dot gnu dot org 0 siblings, 2 replies; 9+ messages in thread From: gcc-bugzilla at gcc dot gnu dot org @ 2005-01-14 19:14 UTC (permalink / raw) To: gcc-bugs gcc generates incorrect code for static members in some cases. Consider the following code: struct C { static __thread int x; static __thread int y; }; __thread int C::x; void g() { int z = C::x; z = C::y; } When this is compiled on an x86 machine with gcc -S, the body of g() is translated as: movl %gs:_ZN1C1xE@NTPOFF, %eax movl %eax, -4(%ebp) movl _ZN1C1yE, %eax movl %eax, -4(%ebp) note that C::x is accessed using an offset from the thread pointer, which is correct. C::y, however, is accessed as if it were an ordinary (not thread-local) static member, which is incorrect. I have also observed this problem on ia64 machines, so it seems to be a general issue. These are similar to the symptoms described in bug 13668, although that was determined to be a glibc issue. I see no way in which glibc could be involved here.
