From d3f78917e1310d7d00e4f955c8e5d30a777f7d35 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Thu, 8 Apr 2021 15:00:03 +0100 Subject: [PATCH] testsuite: Fix sve/mul_2.c failures Some sve/mul_2.c tests were failing because we'd (reasonably) decided to use shifts and adds instead of MULs for some simple negative constants. We'd already needed to avoid that when picking positive constants, so this patch does the same thing for the negative ones. gcc/testsuite/ * gcc.target/aarch64/sve/mul_2.c: Adjust negative constants to avoid conversion to shifts and adds. --- gcc/testsuite/gcc.target/aarch64/sve/mul_2.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/gcc/testsuite/gcc.target/aarch64/sve/mul_2.c b/gcc/testsuite/gcc.target/aarch64/sve/mul_2.c index ff049f5bec01..b57e321c01f8 100644 --- a/gcc/testsuite/gcc.target/aarch64/sve/mul_2.c +++ b/gcc/testsuite/gcc.target/aarch64/sve/mul_2.c @@ -21,14 +21,14 @@ TEST_TYPE (uint8_t, 32, 2, 250) TEST_TYPE (int8_t, 64, -110, 110) TEST_TYPE (uint8_t, 64, 3, 253) -TEST_TYPE (int16_t, 64, -128, 123) +TEST_TYPE (int16_t, 64, -123, 123) TEST_TYPE (uint16_t, 64, 3, 255) -TEST_TYPE (int8_t, 128, -120, 120) +TEST_TYPE (int8_t, 128, -119, 120) TEST_TYPE (uint8_t, 128, 4, 251) -TEST_TYPE (int16_t, 128, -128, 123) +TEST_TYPE (int16_t, 128, -123, 123) TEST_TYPE (uint16_t, 128, 2, 255) -TEST_TYPE (int32_t, 128, -128, 123) +TEST_TYPE (int32_t, 128, -123, 123) TEST_TYPE (uint32_t, 128, 4, 255) /* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, p[0-7]/m, z[0-9]+\.b, z[0-9]+\.b\n} 6 } } */ @@ -37,9 +37,9 @@ TEST_TYPE (uint32_t, 128, 4, 255) /* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, z[0-9]+\.b, #-100\n} 1 } } */ /* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, z[0-9]+\.b, #-110\n} 1 } } */ -/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, z[0-9]+\.b, #-120\n} 1 } } */ -/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.h, z[0-9]+\.h, #-128\n} 2 } } */ -/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.s, z[0-9]+\.s, #-128\n} 1 } } */ +/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, z[0-9]+\.b, #-119\n} 1 } } */ +/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.h, z[0-9]+\.h, #-123\n} 2 } } */ +/* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.s, z[0-9]+\.s, #-123\n} 1 } } */ /* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.b, z[0-9]+\.b, #50\n} 6 } } */ /* { dg-final { scan-assembler-times {\tmul\tz[0-9]+\.h, z[0-9]+\.h, #50\n} 4 } } */ -- 2.47.2
