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.target/m68k/interrupt_thread-1.c | 43 ++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/gcc.target/m68k/interrupt_thread-1.c (limited to 'gcc/testsuite/gcc.target/m68k/interrupt_thread-1.c') diff --git a/gcc/testsuite/gcc.target/m68k/interrupt_thread-1.c b/gcc/testsuite/gcc.target/m68k/interrupt_thread-1.c new file mode 100644 index 000000000..ee7179cd4 --- /dev/null +++ b/gcc/testsuite/gcc.target/m68k/interrupt_thread-1.c @@ -0,0 +1,43 @@ +/* { dg-do compile } */ +/* { dg-options "-mcpu=fidoa -O2 -fomit-frame-pointer" } */ + +/* Check that interrupt_thread attribute works. */ + +#ifdef __mfido__ +extern void foo (void) __attribute__ ((interrupt_thread)); + +int a, b, c, d; + +void bar (void); + +void +foo (void) +{ + int w, x, y, z; + + w = a; + x = b; + y = c; + z = d; + + bar (); + + a = w; + b = x; + c = y; + d = z; +} +#else +/* If the current mutilib is, say, -mcpu=5485, the compiler gets + -mcpu=fidoa -mcpu=5485, where -mcpu=fidoa is overridden.
