From ba34b26564c8c2f30481a8598908ffe71af371de Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Thu, 31 Dec 2020 21:38:05 -0300 Subject: [PATCH] compile gcc.target/arm/{pr78255-2.c,memset-inline-2.c} with -mno-long-calls If the target is configured such that -mlong-call is passed by default, the function calls these tests are trying to detect by scanning the assembly file are performed using long calls, like so: | foo: | @ memset-inline-2.c:12: memset (a, -1, 14); | mov r2, #14 @, | mvn r1, #0 @, | ldr r0, .L2 @, | ldr r3, .L2+4 @ tmp112, | bx r3 @ tmp112 Looking at .L2 (and in particular at .L2+4): | .L2: | .word a | .word memset <<<--- This change adds -mno-long-calls to the list of compiler options to make sure we generate short call code, allowing the assembly matching to pass. This is added unconditionally to the dg-options (as opposed to using dg-additional-options) because this test is already specific to ARM targets, and -mno-long-calls is available on all ARM targets. for gcc/testsuite/ChangeLog * gcc.target/arm/memset-inline-2.c: Add -mno-long-calls to the test's dg-options. * gcc.target/arm/pr78255-2.c: Likewise. --- gcc/testsuite/gcc.target/arm/memset-inline-2.c | 2 +- gcc/testsuite/gcc.target/arm/pr78255-2.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/testsuite/gcc.target/arm/memset-inline-2.c b/gcc/testsuite/gcc.target/arm/memset-inline-2.c index b8195cab8a6..ba1f7ed1f1e 100644 --- a/gcc/testsuite/gcc.target/arm/memset-inline-2.c +++ b/gcc/testsuite/gcc.target/arm/memset-inline-2.c @@ -1,5 +1,5 @@ /* { dg-do run } */ -/* { dg-options "-save-temps -Os -fno-inline" } */ +/* { dg-options "-save-temps -Os -fno-inline -mno-long-calls" } */ #include #include diff --git a/gcc/testsuite/gcc.target/arm/pr78255-2.c b/gcc/testsuite/gcc.target/arm/pr78255-2.c index cc1c1801c37..fd379aecf9c 100644 --- a/gcc/testsuite/gcc.target/arm/pr78255-2.c +++ b/gcc/testsuite/gcc.target/arm/pr78255-2.c @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-O2" } */ +/* { dg-options "-O2 -mno-long-calls" } */ extern int bar (void *); -- 2.30.2
