From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/attr-isr.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/attr-isr.c (limited to 'gcc/testsuite/gcc.dg/attr-isr.c') diff --git a/gcc/testsuite/gcc.dg/attr-isr.c b/gcc/testsuite/gcc.dg/attr-isr.c new file mode 100644 index 000000000..1373c15f4 --- /dev/null +++ b/gcc/testsuite/gcc.dg/attr-isr.c @@ -0,0 +1,20 @@ +/* { dg-do compile { target { { { sh-*-* sh[1234ble]*-*-* } && { ! sh2a*-*-* } } && nonpic } } } */ +/* { dg-skip-if "" { "sh*-*-*" } { "-m2a*" } { "" } } */ +/* { dg-options "-O" } */ +extern void foo (); + +void +(__attribute ((interrupt_handler)) isr)() +{ + foo (); +} + +/* { dg-final { scan-assembler-times "rte" 1} } */ +/* The call will clobber r0..r7, which will need not be saved/restored. + One of these registers will do fine to hold the function address, + hence the all-saved registers r8..r13 don't need to be restored. */ +/* { dg-final { scan-assembler-times "r15\[+\],\[ \t\]*r\[0-9\]\[ \t\]*\n" 8 } } */ +/* { dg-final { scan-assembler-times "\[^f\]r\[0-9\]\[ \t\]*," 8 } } */ +/* { dg-final { scan-assembler-not "\[^f\]r1\[0-3\]" } } */ +/* { dg-final { scan-assembler-times "macl" 2} } */ +/* { dg-final { scan-assembler-not "rte.*\n.*r15\[+\],r\[0-7\]\n" } } */ -- cgit v1.2.3
