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/negint.c | 53 +++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 libffi/testsuite/libffi.call/negint.c (limited to 'libffi/testsuite/libffi.call/negint.c') diff --git a/libffi/testsuite/libffi.call/negint.c b/libffi/testsuite/libffi.call/negint.c new file mode 100644 index 000000000..316811302 --- /dev/null +++ b/libffi/testsuite/libffi.call/negint.c @@ -0,0 +1,53 @@ +/* Area: ffi_call + Purpose: Check that negative integers are passed correctly. + Limitations: none. + PR: none. + Originator: From the original ffitest.c */ + +/* { dg-do run } */ +/* { dg-options -O2 } */ + +#include "ffitest.h" + +static int checking(int a, short b, signed char c) +{ + + return (a < 0 && b < 0 && c < 0); +} + +int main (void) +{ + ffi_cif cif; + ffi_type *args[MAX_ARGS]; + void *values[MAX_ARGS]; + ffi_arg rint; + + signed int si; + signed short ss; + signed char sc; + + args[0] = &ffi_type_sint; + values[0] = &si; + args[1] = &ffi_type_sshort; + values[1] = &ss; + args[2] = &ffi_type_schar; + values[2] = ≻ + + /* Initialize the cif */ + CHECK(ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 3, + &ffi_type_sint, args) == FFI_OK); + + si = -6; + ss = -12; + sc = -1; + + checking (si, ss, sc); + + ffi_call(&cif, FFI_FN(checking), &rint, values); + + printf ("%d vs %d\n", (int)rint, checking (si, ss, sc)); + + CHECK(rint != 0); + + exit (0); +} -- cgit v1.2.3
