From bc771e6c3a2b1fe74328639a00531fc0c3923e43 Mon Sep 17 00:00:00 2001 From: Stam Markianos-Wright Date: Wed, 25 Nov 2020 12:50:06 +0000 Subject: [PATCH] arm: Add test that was missing from old commit [PR91816] A while back I submitted GCC10 commit: 44f77a6dea2f312ee1743f3dde465c1b8453ee13 for PR91816. Turns out I was an idiot and forgot to include the test in the actual git commit. Tested that the test still passes on a cross arm-none-eabi and also in a Cortex A-15 bootstrap with no regressions. gcc/testsuite/ChangeLog: PR target/91816 * gcc.target/arm/pr91816.c: New test. --- gcc/testsuite/gcc.target/arm/pr91816.c | 63 ++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/pr91816.c diff --git a/gcc/testsuite/gcc.target/arm/pr91816.c b/gcc/testsuite/gcc.target/arm/pr91816.c new file mode 100644 index 00000000000..b0a0ea1d495 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/pr91816.c @@ -0,0 +1,63 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target arm_thumb2_ok } */ +/* { dg-additional-options "-mthumb" } */ +/* { dg-timeout-factor 4.0 } */ + +int printf(const char *, ...); + +#define HW0 printf("Hello World!\n"); +#define HW1 HW0 HW0 HW0 HW0 HW0 HW0 HW0 HW0 HW0 HW0 +#define HW2 HW1 HW1 HW1 HW1 HW1 HW1 HW1 HW1 HW1 HW1 +#define HW3 HW2 HW2 HW2 HW2 HW2 HW2 HW2 HW2 HW2 HW2 +#define HW4 HW3 HW3 HW3 HW3 HW3 HW3 HW3 HW3 HW3 HW3 +#define HW5 HW4 HW4 HW4 HW4 HW4 HW4 HW4 HW4 HW4 HW4 + +__attribute__((noinline,noclone)) void f1 (int a) +{ + if (a) { HW0 } +} + +__attribute__((noinline,noclone)) void f2 (int a) +{ + if (a) { HW3 } +} + + +__attribute__((noinline,noclone)) void f3 (int a) +{ + if (a) { HW5 } +} + +__attribute__((noinline,noclone)) void f4 (int a) +{ + if (a == 1) { HW0 } +} + +__attribute__((noinline,noclone)) void f5 (int a) +{ + if (a == 1) { HW3 } +} + + +__attribute__((noinline,noclone)) void f6 (int a) +{ + if (a == 1) { HW5 } +} + + +int main(void) +{ + f1(0); + f2(0); + f3(0); + f4(0); + f5(0); + f6(0); + return 0; +} + + +/* { dg-final { scan-assembler-times "beq\\t.L\[0-9\]" 2 } } */ +/* { dg-final { scan-assembler-times "beq\\t.Lbcond\[0-9\]" 1 } } */ +/* { dg-final { scan-assembler-times "bne\\t.L\[0-9\]" 2 } } */ +/* { dg-final { scan-assembler-times "bne\\t.Lbcond\[0-9\]" 1 } } */ -- 2.30.2
