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/20020411-1.c | 54 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/20020411-1.c (limited to 'gcc/testsuite/gcc.dg/20020411-1.c') diff --git a/gcc/testsuite/gcc.dg/20020411-1.c b/gcc/testsuite/gcc.dg/20020411-1.c new file mode 100644 index 000000000..47a8fed50 --- /dev/null +++ b/gcc/testsuite/gcc.dg/20020411-1.c @@ -0,0 +1,54 @@ +/* PR c/6223 + This testcase ICEd in internal check because a constant was not truncated + for its mode. */ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ +/* { dg-options "-O2 -march=i686" { target { { i?86-*-* x86_64-*-* } && ilp32 } } } */ + +#if __INT_MAX__ > 32767 + +typedef struct +{ + unsigned a : 16; + unsigned b : 16; + unsigned c : 5; + unsigned d : 2; + unsigned e : 1; + unsigned f : 4; + unsigned g : 1; + unsigned h : 1; + unsigned i : 1; + unsigned j : 1; +} T; + +inline void +foo (T *x, unsigned int y) +{ + if ((x->j = (y >= 0x100000))) + y >>= 12; + x->a = y; + x->f = (y >> 16); +} + +void __attribute__((noinline)) +bar (T *x) +{ +} + +void +baz (unsigned int x, unsigned char y) +{ + T t; + + foo (&t, x - 1); + t.e = 1; + t.c = y; + t.g = 0; + t.h = 0; + t.i = (y & 0x40) != 0; + if (x == 1) + foo (&t, 1); + bar (&t); +} + +#endif /* __INT_MAX__ */ -- cgit v1.2.3
