charset=utf-8; format=fixed Content-Disposition: inline The tests currently depending on memcpy lowering forming stps at -O0, but we no longer want to form stps during memcpy lowering, but instead in the load/store pair fusion pass. This patch therefore tweaks affected tests to enable optimizations (-O1), and adjusts the tests to avoid parts of the structures being optimized away where necessary. OK for trunk? gcc/testsuite/ChangeLog: * gcc.target/aarch64/auto-init-padding-1.c: Add -O to options, adjust test to work with optimizations enabled. * gcc.target/aarch64/auto-init-padding-2.c: Add -O to options. * gcc.target/aarch64/auto-init-padding-3.c: Add -O to options, adjust test to work with optimizations enabled. * gcc.target/aarch64/auto-init-padding-4.c: Likewise. * gcc.target/aarch64/auto-init-padding-9.c: Likewise. --- gcc/testsuite/gcc.target/aarch64/auto-init-padding-1.c | 8 +++++--- gcc/testsuite/gcc.target/aarch64/auto-init-padding-2.c | 2 +- gcc/testsuite/gcc.target/aarch64/auto-init-padding-3.c | 7 ++++--- gcc/testsuite/gcc.target/aarch64/auto-init-padding-4.c | 4 ++-- gcc/testsuite/gcc.target/aarch64/auto-init-padding-9.c | 7 ++++--- 5 files changed, 16 insertions(+), 12 deletions(-) --q5EyAIQE/y4YoTbr Content-Type: text/x-patch; charset=utf-8; name="0003-aarch64-testsuite-Fix-up-auto-init-padding-tests.patch" Content-Disposition: attachment; filename="0003-aarch64-testsuite-Fix-up-auto-init-padding-tests.patch" Content-Transfer-Encoding: 8bit diff --git a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-1.c b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-1.c index c747ebdcdf7..7027454dc74 100644 --- a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-1.c +++ b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-1.c @@ -1,17 +1,19 @@ /* Verify zero initialization for structure type automatic variables with padding. */ /* { dg-do compile } */ -/* { dg-options "-ftrivial-auto-var-init=zero" } */ +/* { dg-options "-O -ftrivial-auto-var-init=zero" } */ struct test_aligned { int internal1; long long internal2; } __attribute__ ((aligned(64))); -int foo () +void bar (struct test_aligned *); + +void foo () { struct test_aligned var; - return var.internal1; + bar(&var); } /* { dg-final { scan-assembler-times {stp\tq[0-9]+, q[0-9]+,} 2 } } */ diff --git a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-2.c b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-2.c index 6e280904da1..d3b6591c9b0 100644 --- a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-2.c +++ b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-2.c @@ -1,7 +1,7 @@ /* Verify pattern initialization for structure type automatic variables with padding. */ /* { dg-do compile } */ -/* { dg-options "-ftrivial-auto-var-init=pattern" } */ +/* { dg-options "-O -ftrivial-auto-var-init=pattern" } */ struct test_aligned { int internal1; diff --git a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-3.c b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-3.c index 9ddea58b468..aad4bb8944f 100644 --- a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-3.c +++ b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-3.c @@ -1,7 +1,7 @@ /* Verify zero initialization for nested structure type automatic variables with padding. */ /* { dg-do compile } */ -/* { dg-options "-ftrivial-auto-var-init=zero" } */ +/* { dg-options "-O -ftrivial-auto-var-init=zero" } */ struct test_aligned { unsigned internal1; @@ -16,11 +16,12 @@ struct test_big_hole { struct test_aligned four; } __attribute__ ((aligned(64))); +void bar (struct test_big_hole *); -int foo () +void foo () { struct test_big_hole var; - return var.four.internal1; + bar (&var); } /* { dg-final { scan-assembler-times {stp\tq[0-9]+, q[0-9]+,} 4 } } */ diff --git a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-4.c b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-4.c index 75bba82ed34..efd310f054d 100644 --- a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-4.c +++ b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-4.c @@ -1,7 +1,7 @@ /* Verify pattern initialization for nested structure type automatic variables with padding. */ /* { dg-do compile } */ -/* { dg-options "-ftrivial-auto-var-init=pattern" } */ +/* { dg-options "-O -ftrivial-auto-var-init=pattern" } */ struct test_aligned { unsigned internal1; @@ -23,4 +23,4 @@ int foo () return var.four.internal1; } -/* { dg-final { scan-assembler-times {stp\tq[0-9]+, q[0-9]+,} 5 } } */ +/* { dg-final { scan-assembler-times {stp\tq[0-9]+, q[0-9]+,} 4 } } */ diff --git a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-9.c b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-9.c index 0f1930f813e..64ed8f11fe6 100644 --- a/gcc/testsuite/gcc.target/aarch64/auto-init-padding-9.c +++ b/gcc/testsuite/gcc.target/aarch64/auto-init-padding-9.c @@ -1,7 +1,7 @@ /* Verify zero initialization for array type with structure element with padding. */ /* { dg-do compile } */ -/* { dg-options "-ftrivial-auto-var-init=zero" } */ +/* { dg-options "-O -ftrivial-auto-var-init=zero" } */ struct test_trailing_hole { int one; @@ -11,11 +11,12 @@ struct test_trailing_hole { /* "sizeof(unsigned long) - 1" byte padding hole here. */ }; +void bar (void *); -int foo () +void foo () { struct test_trailing_hole var[10]; - return var[2].four; + bar (var); } /* { dg-final { scan-assembler-times {stp\tq[0-9]+, q[0-9]+,} 5 } } */ --q5EyAIQE/y4YoTbr--
