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.
