http://d.puremagic.com/issues/show_bug.cgi?id=9745 Summary: Allow non-thread local static variables to have their address taken in CTFE Product: D Version: D1 & D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: clugdbug@yahoo.com.au --- Comment #0 from Don <clugdbug@yahoo.com.au> 2013-03-18 04:59:41 PDT --- Split off from bug 9744. Applies to both shared and __gshared, (or any static variable in D1). ------- shared int x1; shared(int) * foo() { return & x1; } shared int *p1 = & x1; // OK shared int *p2 = foo(); // ERROR - & x1 is not valid in CTFE. ------- Obviously, any attempt to dereference &x1 must fail. Likewise, it must not be valid to take the address of a thread-local variable. This is the largest remaining difference between constant-folding and CTFE. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

It's already supported in the const-folding code, now support it in CTFE as well. This commit adds full support for pointer arithmetic. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
