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/g++.dg/dfp/mangle-mode.C | 37 ++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/g++.dg/dfp/mangle-mode.C (limited to 'gcc/testsuite/g++.dg/dfp/mangle-mode.C') diff --git a/gcc/testsuite/g++.dg/dfp/mangle-mode.C b/gcc/testsuite/g++.dg/dfp/mangle-mode.C new file mode 100644 index 000000000..ac30cb323 --- /dev/null +++ b/gcc/testsuite/g++.dg/dfp/mangle-mode.C @@ -0,0 +1,37 @@ +// { dg-do compile } + +// Check that the compiler mangles types defined with decimal float +// modes according to the vendor-neutral C++ ABI. + +typedef float _Decimal32 __attribute__((mode(SD))); +typedef float _Decimal64 __attribute__((mode(DD))); +typedef float _Decimal128 __attribute__((mode(TD))); + +extern void foo32 (_Decimal32 a, _Decimal32 &b, _Decimal32 *c); +extern void foo64 (_Decimal64 *a, _Decimal64 b, _Decimal64 &c); +extern void foo128 (_Decimal128 &a, _Decimal128 *b, _Decimal128 c); + +void +bar32 (void) +{ + _Decimal32 x, y, z; + foo32 (x, y, &z); +} + +void +bar64 (void) +{ + _Decimal64 x, y, z; + foo64 (&x, y, z); +} + +void +bar128 (void) +{ + _Decimal128 x, y, z; + foo128 (x, &y, z); +} + +// { dg-final { scan-assembler "Z5foo32DfRDfPDf" } } +// { dg-final { scan-assembler "Z5foo64PDdDdRDd" } } +// { dg-final { scan-assembler "Z6foo128RDePDeDe" } } -- cgit v1.2.3
