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/cls_longdouble_va.c | 60 ++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 libffi/testsuite/libffi.call/cls_longdouble_va.c (limited to 'libffi/testsuite/libffi.call/cls_longdouble_va.c') diff --git a/libffi/testsuite/libffi.call/cls_longdouble_va.c b/libffi/testsuite/libffi.call/cls_longdouble_va.c new file mode 100644 index 000000000..07780ede4 --- /dev/null +++ b/libffi/testsuite/libffi.call/cls_longdouble_va.c @@ -0,0 +1,60 @@ +/* Area: ffi_call, closure_call + Purpose: Test long doubles passed in variable argument lists. + Limitations: none. + PR: none. + Originator: Blake Chaffin 6/6/2007 */ + +/* { dg-do run { xfail strongarm*-*-* xscale*-*-* } } */ +/* { dg-output "" { xfail avr32*-*-* x86_64-*-mingw* } } */ +/* { dg-output "" { xfail mips-sgi-irix6* } } PR libffi/46660 */ +/* { dg-skip-if "" arm*-*-* { "-mfloat-abi=hard" } { "" } } */ + +#include "ffitest.h" + +static void +cls_longdouble_va_fn(ffi_cif* cif __UNUSED__, void* resp, + void** args, void* userdata __UNUSED__) +{ + char* format = *(char**)args[0]; + long double ldValue = *(long double*)args[1]; + + *(ffi_arg*)resp = printf(format, ldValue); +} + +int main (void) +{ + ffi_cif cif; + void *code; + ffi_closure *pcl = ffi_closure_alloc(sizeof(ffi_closure), &code); + void* args[3]; + ffi_type* arg_types[3]; + + char* format = "%.1Lf\n"; + long double ldArg = 7; + ffi_arg res = 0; + + arg_types[0] = &ffi_type_pointer; + arg_types[1] = &ffi_type_longdouble; + arg_types[2] = NULL; + + CHECK(ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 2, &ffi_type_sint, + arg_types) == FFI_OK); + + args[0] = &format; + args[1] = &ldArg; + args[2] = NULL; + + ffi_call(&cif, FFI_FN(printf), &res, args); + // { dg-output "7.0" } + printf("res: %d\n", (int) res); + // { dg-output "\nres: 4" } + + CHECK(ffi_prep_closure_loc(pcl, &cif, cls_longdouble_va_fn, NULL, code) == FFI_OK); + + res = ((int(*)(char*, long double))(code))(format, ldArg); + // { dg-output "\n7.0" } + printf("res: %d\n", (int) res); + // { dg-output "\nres: 4" } + + exit(0); +} -- cgit v1.2.3
