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/struct8.c | 80 ++++++++++++++++++++++++++++++++++ 1 file changed, 80 insertions(+) create mode 100644 libffi/testsuite/libffi.call/struct8.c (limited to 'libffi/testsuite/libffi.call/struct8.c') diff --git a/libffi/testsuite/libffi.call/struct8.c b/libffi/testsuite/libffi.call/struct8.c new file mode 100644 index 000000000..c773ac7b5 --- /dev/null +++ b/libffi/testsuite/libffi.call/struct8.c @@ -0,0 +1,80 @@ +/* Area: ffi_call + Purpose: Check structures. + Limitations: none. + PR: none. + Originator: From the original ffitest.c */ + +/* { dg-do run } */ +#include "ffitest.h" +typedef struct +{ + float f1; + float f2; + float f3; + float f4; +} test_structure_8; + +static test_structure_8 struct8 (test_structure_8 ts) +{ + ts.f1 += 1; + ts.f2 += 1; + ts.f3 += 1; + ts.f4 += 1; + + return ts; +} + +int main (void) +{ + ffi_cif cif; + ffi_type *args[MAX_ARGS]; + void *values[MAX_ARGS]; + ffi_type ts8_type; + ffi_type *ts8_type_elements[5]; + ts8_type.size = 0; + ts8_type.alignment = 0; + ts8_type.type = FFI_TYPE_STRUCT; + ts8_type.elements = ts8_type_elements; + ts8_type_elements[0] = &ffi_type_float; + ts8_type_elements[1] = &ffi_type_float; + ts8_type_elements[2] = &ffi_type_float; + ts8_type_elements[3] = &ffi_type_float; + ts8_type_elements[4] = NULL; + + test_structure_8 ts8_arg; + + /* This is a hack to get a properly aligned result buffer */ + test_structure_8 *ts8_result = + (test_structure_8 *) malloc (sizeof(test_structure_8)); + + args[0] = &ts8_type; + values[0] = &ts8_arg; + + /* Initialize the cif */ + CHECK(ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, &ts8_type, args) == FFI_OK); + + ts8_arg.f1 = 5.55f; + ts8_arg.f2 = 55.5f; + ts8_arg.f3 = -5.55f; + ts8_arg.f4 = -55.5f; + + printf ("%g\n", ts8_arg.f1); + printf ("%g\n", ts8_arg.f2); + printf ("%g\n", ts8_arg.f3); + printf ("%g\n", ts8_arg.f4); + + ffi_call(&cif, FFI_FN(struct8), ts8_result, values); + + printf ("%g\n", ts8_result->f1); + printf ("%g\n", ts8_result->f2); + printf ("%g\n", ts8_result->f3); + printf ("%g\n", ts8_result->f4); + + CHECK(ts8_result->f1 == 5.55f + 1); + CHECK(ts8_result->f2 == 55.5f + 1); + CHECK(ts8_result->f3 == -5.55f + 1); + CHECK(ts8_result->f4 == -55.5f + 1); + + free (ts8_result); + exit(0); +} -- cgit v1.2.3
