Test g++.dg/ext/altivec-3.C has been failing for mainline on powerpc64-linux systems without VMX hardware since this patch, a fix for PR20103, was added:
http://gcc.gnu.org/viewcvs?view=rev&rev=114119 r114119 | mmitchel | 2006-05-25 20:18:26 +0000 (Thu, 25 May 2006) The test calls a function at runtime to determine if VMX hardware is available and if not, skips the rest of the test. It now fails because vector global variables are initialized by constructors instead of at compile time. Here's a minimal example: __vector signed int vsi = (__vector signed int) {40, 41, 42, 43}; int main () { return 0; } If the new behavior is expected then I'll change the test to be compile-only on systems without VMX hardware. -- Summary: vectors initialized in ctors, not at compile time, cause altivec-3.C failure Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org GCC target triplet: powerpc-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28113
