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/gcc.c-torture/unsorted/udconvert.c | 30 ++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/unsorted/udconvert.c (limited to 'gcc/testsuite/gcc.c-torture/unsorted/udconvert.c') diff --git a/gcc/testsuite/gcc.c-torture/unsorted/udconvert.c b/gcc/testsuite/gcc.c-torture/unsorted/udconvert.c new file mode 100644 index 000000000..31b494fe0 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/unsorted/udconvert.c @@ -0,0 +1,30 @@ +double +unsigned_to_double1 (u) + unsigned u; +{ + double d; + d = (int) u; /* convert as from a *signed* integer */ + return ((int) u < 0) + ? d + 4294967296.0 + : d; +} + +/* Alternatively */ + +double +unsigned_to_double2 (u) + unsigned u; +{ + double d; + u -= 2147483648; /* complement sign bit */ + d = (int) u; /* convert as from a *signed* integer */ + return d + 2147483648.0; +} + +unsigned +double_to_unsigned (d) + double d; +{ + d += 2147483648.0; + return ((int) d) - 2147483648; +} -- cgit v1.2.3
