Sorry the slow reply. I'm not well versed on the all AArch32 combinations but it looks good to me.

[PATCH] testsuite/arm: Fix scan-assembler-times in pr96770.c with movt/movw
The previous change to this testcase missed the fact that the data may be accessed via an anchor, depending on the optimization level, leading to false failures. This patch restricts matching to upper16:lower16 followed by non-spaces, followed by +4 (in f4) or +320 (in f5). Using '.*' instead of '[^ \]' would match accross the whole assembly file, which is not what we want, hence the limitation with spaces. 2021-03-29 Christophe Lyon gcc/testsuite/ PR target/96770 * gcc.target/arm/pure-code/pr96770.c: Fix scan-assembler-times with movt/movw. --- gcc/testsuite/gcc.target/arm/pure-code/pr96770.c | 12 +++- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/gcc/testsuite/gcc.target/arm/pure-code/pr96770.c b/gcc/testsuite/gcc.target/arm/pure-code/pr96770.c index ae1bd10..3c69614 100644 --- a/gcc/testsuite/gcc.target/arm/pure-code/pr96770.c +++ b/gcc/testsuite/gcc.target/arm/pure-code/pr96770.c @@ -4,12 +4,13 @@ int arr[1000]; int *f4 (void) { return [1]; } -/* For cortex-m0 (thumb-1/v6m), we generate 4 movs with upper/lower:#arr+4. */ +/* For cortex-m0 (thumb-1/v6m), we generate 2 pairs of movs/adds with upper/lower:#arr+4. */ /* { dg-final { scan-assembler-times "arr\\+4" 4 { target { { ! arm_thumb1_movt_ok } && { ! arm_thumb2_ok } } } } } */ /* For cortex-m with movt/movw (thumb-1/v8m.base or thumb-2), we - generate a movt/movw pair with upper/lower:#arr+4. */ -/* { dg-final { scan-assembler-times "arr\\+4" 2 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ + generate a movt/movw pair with upper/lower:#arr+4 possibly via an anchor. */ +/* { dg-final { scan-assembler-times "upper16:\[^ \]+.\\+4" 1 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ +/* { dg-final { scan-assembler-times "lower16:\[^ \]+\\+4" 1 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ int *f5 (void) { return [80]; } @@ -17,5 +18,6 @@ int *f5 (void) { return [80]; } /* { dg-final { scan-assembler-times "arr\\+320" 1 { target { { ! arm_thumb1_movt_ok } && { ! arm_thumb2_ok } } } } } */ /* For cortex-m with movt/movw (thumb-1/v8m.base or thumb-2), we - generate a movt/movw pair with upper/lower:arr+320. */ -/* { dg-final { scan-assembler-times "arr\\+320" 2 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ + generate a movt/movw pair with upper/lower:arr+320 possibly via an anchor. */ +/* { dg-final { scan-assembler-times "upper16:\[^ \]+\\+320" 1 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ +/* { dg-final { scan-assembler-times "lower16:\[^ \]+\\+320" 1 { target { arm_thumb1_movt_ok || arm_thumb2_ok } } } } */ -- 2.7.4
