Testsuite: GCN is always PIE.
The GCN/HSA loader ignores the load address and uses a random location, so we build all GCN binaries as PIE, by default. This patch makes the necessary testsuite adjustments to make this work correctly. 2019-01-17 Andrew Stubbs <ams@codesourcery.com> gcc/testsuite/ * gcc.dg/graphite/scop-19.c: Check pie_enabled. * gcc.dg/pic-1.c: Disable on amdgcn. * gcc.dg/pic-2.c: Disable on amdgcn. * gcc.dg/pic-3.c: Disable on amdgcn. * gcc.dg/pic-4.c: Disable on amdgcn. * gcc.dg/pie-3.c: Disable on amdgcn. * gcc.dg/pie-4.c: Disable on amdgcn. * gcc.dg/uninit-19.c: Check pie_enabled. * lib/target-supports.exp (check_effective_target_pie): Add amdgcn.
