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.dg/pr38364.c | 79 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr38364.c (limited to 'gcc/testsuite/gcc.dg/pr38364.c') diff --git a/gcc/testsuite/gcc.dg/pr38364.c b/gcc/testsuite/gcc.dg/pr38364.c new file mode 100644 index 000000000..23f72de74 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr38364.c @@ -0,0 +1,79 @@ +/* PR middle-end/38364 */ +/* { dg-do run } */ +/* { dg-options "-O2 -ftrapv" } */ + +extern void abort (void); + +static inline short +f1 (short x, short y) +{ + if (x > 0) + { + if (y > 0) + { + if (x > __SHRT_MAX__ / y) + return x; + } + else if (y < (-__SHRT_MAX__ - 1) / x) + return x; + } + else + { + if (y > 0) + { + if (x < (-__SHRT_MAX__ - 1) / y) + return x; + } + else if (x != 0 && y < __SHRT_MAX__ / x) + return x; + } + return x * y; +} + +static inline signed char +f2 (signed char x, signed char y) +{ + if (((x ^ y) & (((x ^ ((x ^ y) & (1 << (__CHAR_BIT__ - 1)))) - y) ^ y)) < 0) + return x; + return x - y; +} + +unsigned int v; + +int +f3 (int x, unsigned int y) +{ + f1 (1, 1); + return 1; +} + +int +f4 (unsigned short x) +{ + v = x; + return 1; +} + +int +f5 (int x) +{ + if (f2 (x, 1)) + f1 (1, f4 (1)); + return x; +} + +int +f6 (unsigned int x) +{ + f4 (x < (1 != f5 (0))); + return x; +} + +int +main (void) +{ + f6 (1); + if (v != 0) + abort (); + return 0; +} -- cgit v1.2.3
