I was wondering if I could get some help/advice from a testsuite expert. I have a patch that I want to submit that makes sure elements of an array are not given an alignment greater than their size.
See http://gcc.gnu.org/ml/gcc/2005-03/msg00729.html This test was causing a bunch of regressions, most of which have been fixed now by Jakub and Dorit. But the patch still causes a couple of regressions in the gcc.dg/compat tests that I have been unable to fix. The failures I get are: FAIL: tmpdir-gcc.dg-struct-layout-1/t002 c_compat_x_tst.o compile FAIL: tmpdir-gcc.dg-struct-layout-1/t002 c_compat_y_tst.o compile FAIL: tmpdir-gcc.dg-struct-layout-1/t027 c_compat_x_tst.o compile FAIL: tmpdir-gcc.dg-struct-layout-1/t027 c_compat_y_tst.o compile There used to be more layout failures but Jakub submitted a patch earlier (May 2005) that fixed all but these. I know that the gcc.dg-struct-layout-1_generate program creates a t002_test.h header file and that that file contains: T(582,void * atal8 a[2];double b;unsigned short int c;,F(582,a[0],(void *)&intarray[78],(void *)&intarray[187])F(582,b,198407.656250,218547.203125)F(582,c,55499U,5980U)) and that atal8 is a define for "__attribute__((aligned (8)))" which means that we get "void * __attribute__((aligned (8))) a[2];" and that is what is causing the problem (8 byte alignement of the elements in an array where the elements are only 4 bytes long. But what I have not been able to do is to figure out how to get gcc.dg-struct-layout-1_generate to stop generating this type. Even after looking at Jakubs patch that fixed the other layout failures, I haven't been able to come up with a fix. Can anyone help me with this? Steve Ellcey [EMAIL PROTECTED]
