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/c-c++-common/dfp/struct-layout-1.c | 71 ++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/struct-layout-1.c (limited to 'gcc/testsuite/c-c++-common/dfp/struct-layout-1.c') diff --git a/gcc/testsuite/c-c++-common/dfp/struct-layout-1.c b/gcc/testsuite/c-c++-common/dfp/struct-layout-1.c new file mode 100644 index 000000000..2a9d7304f --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/struct-layout-1.c @@ -0,0 +1,71 @@ +#include +#include "dfp-dbg.h" + +struct S1 +{ + _Decimal64 a[0]; +}; + +struct S2 +{ + struct + { + _Decimal64 e; + } b[0]; +}; + +struct S3 +{ + union + { + _Decimal64 c; + } a[0]; +}; + +struct S4 +{ + int a[0]; + _Decimal64 b[0]; +}; + +struct S5 +{ + union + { + _Decimal64 c[0]; + } a; +}; + +int check_var (int z, ...) +{ + long long result; + va_list ap; + va_start (ap, z); + va_arg (ap, struct S1); + result = va_arg (ap, long long); + va_end (ap); + + return (result == 2LL); +} + +int main () +{ + struct S1 s1; + struct S2 s2; + struct S3 s3; + struct S4 s4; + struct S5 s5; + + if (check_var (2, s1, 2LL) == 0) + FAILURE; + if (check_var (2, s2, 2LL) == 0) + FAILURE; + if (check_var (2, s3, 2LL) == 0) + FAILURE; + if (check_var (2, s4, 2LL) == 0) + FAILURE; + if (check_var (2, s5, 2LL) == 0) + FAILURE; + + FINISH +} -- cgit v1.2.3
