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/pragma-isr-nosave_low_regs.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pragma-isr-nosave_low_regs.c (limited to 'gcc/testsuite/gcc.dg/pragma-isr-nosave_low_regs.c') diff --git a/gcc/testsuite/gcc.dg/pragma-isr-nosave_low_regs.c b/gcc/testsuite/gcc.dg/pragma-isr-nosave_low_regs.c new file mode 100644 index 000000000..c71c88cb7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pragma-isr-nosave_low_regs.c @@ -0,0 +1,20 @@ +/* { dg-do compile { target { { sh-*-* sh[1234ble]*-*-* } && nonpic } } } */ +/* { dg-options "-O" } */ +extern void foo (); +#pragma interrupt +#pragma nosave_low_regs +void +isr() +{ + foo (); +} + +/* { dg-final { scan-assembler-times "rte" 1} } */ +/* A call will clobber all call-saved registers, but because of + #pragma nosave_low_regs, r0..r7 need not be saved/restored. + One of these registers will also do fine to hold the function address. + Call-saved registers r8..r13 also don't need to be restored. */ +/* { dg-final { scan-assembler-not "\[^f\]r\[0-9\]\[ \t\]*," } } */ +/* { dg-final { scan-assembler-not "\[^f\]r\[89\]" } } */ +/* { dg-final { scan-assembler-not "\[^f\]r1\[,0-3\]" } } */ +/* { dg-final { scan-assembler-times "macl" 2} } */ -- cgit v1.2.3
