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/20041219-1.c | 47 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/20041219-1.c (limited to 'gcc/testsuite/gcc.dg/20041219-1.c') diff --git a/gcc/testsuite/gcc.dg/20041219-1.c b/gcc/testsuite/gcc.dg/20041219-1.c new file mode 100644 index 000000000..4fdc9540d --- /dev/null +++ b/gcc/testsuite/gcc.dg/20041219-1.c @@ -0,0 +1,47 @@ +/* PR18191 Struct member is not getting default-initialized. + Origin: Grigory Zagorodnev */ + +/* { dg-do run } */ + +extern int printf (__const char *__restrict __format, ...); + +typedef struct S { + const char* s; + int i; +} S; + +void +foo (void) +{ + S dummy[2]; + unsigned i; + + /* Put some garbage on the stack. */ + for (i = 0; i < sizeof(dummy); i++) + ((char *)&dummy)[i] = -1; +} + +int +bar (void) +{ + /* Allocate object on the stack. */ + S obj[2] = { {"m0"}, {"m1"} }; + + /* Assume fields those not explicitly initialized + are default initialized to 0 [8.5.1/7 and 8.5/5]. */ + if (obj[0].i == 0) + return 0; + else + { + printf("Failed: obj[0].i == '%d', expecting '0'\n", obj[0].i); + return 1; + } +} + +int +main (void) +{ + foo(); + return bar(); +} + -- cgit v1.2.3
