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. --- libffi/testsuite/libffi.call/struct1.c | 65 ++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 libffi/testsuite/libffi.call/struct1.c (limited to 'libffi/testsuite/libffi.call/struct1.c') diff --git a/libffi/testsuite/libffi.call/struct1.c b/libffi/testsuite/libffi.call/struct1.c new file mode 100644 index 000000000..ea76c8544 --- /dev/null +++ b/libffi/testsuite/libffi.call/struct1.c @@ -0,0 +1,65 @@ +/* Area: ffi_call + Purpose: Check structures. + Limitations: none. + PR: none. + Originator: From the original ffitest.c */ + +/* { dg-do run } */ +#include "ffitest.h" + +typedef struct +{ + unsigned char uc; + double d; + unsigned int ui; +} test_structure_1; + +static test_structure_1 struct1(test_structure_1 ts) +{ + ts.uc++; + ts.d--; + ts.ui++; + + return ts; +} + +int main (void) +{ + ffi_cif cif; + ffi_type *args[MAX_ARGS]; + void *values[MAX_ARGS]; + ffi_type ts1_type; + ffi_type *ts1_type_elements[4]; + ts1_type.size = 0; + ts1_type.alignment = 0; + ts1_type.type = FFI_TYPE_STRUCT; + ts1_type.elements = ts1_type_elements; + ts1_type_elements[0] = &ffi_type_uchar; + ts1_type_elements[1] = &ffi_type_double; + ts1_type_elements[2] = &ffi_type_uint; + ts1_type_elements[3] = NULL; + + test_structure_1 ts1_arg; + /* This is a hack to get a properly aligned result buffer */ + test_structure_1 *ts1_result = + (test_structure_1 *) malloc (sizeof(test_structure_1)); + + args[0] = &ts1_type; + values[0] = &ts1_arg; + + /* Initialize the cif */ + CHECK(ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ts1_type, args) == FFI_OK); + + ts1_arg.uc = '\x01'; + ts1_arg.d = 3.14159; + ts1_arg.ui = 555; + + ffi_call(&cif, FFI_FN(struct1), ts1_result, values); + + CHECK(ts1_result->ui == 556); + CHECK(ts1_result->d == 3.14159 - 1); + + free (ts1_result); + exit(0); +} -- cgit v1.2.3
