From: "jakub at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/25261] [gomp] Nested function calls in #pragma omp parallel blocks Date: Mon, 11 Sep 2006 15:47:00 -0000 [thread overview] Message-ID: <20060911154656.10592.qmail@sourceware.org> (raw) In-Reply-To: <bug-25261-87@http.gcc.gnu.org/bugzilla/> ------- Comment #4 from jakub at gcc dot gnu dot org 2006-09-11 15:46 ------- Furthermore, I have no idea what would: extern void abort (void); int baz (int (*bar) (void)) { return bar (); } void foo (int *j) { int i = 5; int (*fn) (void); int bar (void) { return i + 1; } fn = bar; if (bar (fn) != 6) #pragma omp atomic ++j; #pragma omp sections private (i) { #pragma omp section { i = 6; if (baz (fn) != 7) #pragma omp atomic ++*j; } #pragma omp section { if (baz (fn) != 6) #pragma omp atomic ++*j; } } } int main (void) { int j = 0; #pragma omp parallel num_threads (2) foo (&j); if (j) abort (); return 0; } be supposed to do. Do other openmp compilers support nested C functions? If so, what they are doing here? It would be easy to say that e.g. all non-local vars in nested functions are implicitly shared (i.e. we always reference the original parent function's variables, not any remapped ones). But can we do the same in Fortran where nested functions are part of the standard? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25261
