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_3byte2.c | 90 +++++++++++++++++++++++++++++++ 1 file changed, 90 insertions(+) create mode 100644 libffi/testsuite/libffi.call/cls_3byte2.c (limited to 'libffi/testsuite/libffi.call/cls_3byte2.c') diff --git a/libffi/testsuite/libffi.call/cls_3byte2.c b/libffi/testsuite/libffi.call/cls_3byte2.c new file mode 100644 index 000000000..01770a075 --- /dev/null +++ b/libffi/testsuite/libffi.call/cls_3byte2.c @@ -0,0 +1,90 @@ +/* Area: ffi_call, closure_call + Purpose: Check structure passing with different structure size. + Especially with small structures which may fit in one + register.
