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/execute/20020412-1.c | 56 ++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20020412-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20020412-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20020412-1.c b/gcc/testsuite/gcc.c-torture/execute/20020412-1.c new file mode 100644 index 000000000..df0efe008 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20020412-1.c @@ -0,0 +1,56 @@ +/* PR c/3711 + This testcase ICEd on IA-32 at -O0 and was miscompiled otherwise, + because std_expand_builtin_va_arg didn't handle variable size types. */ + +#include + +extern void abort (void); +extern void exit (int); + +void bar (int c) +{ + static int d = '0'; + + if (c != d++) + abort (); + if (c < '0' || c > '9') + abort (); +} + +void foo (int size, ...) +{ + struct + { + char x[size]; + } d; + va_list ap; + int i; + + va_start (ap, size); + d = va_arg (ap, typeof (d)); + for (i = 0; i < size; i++) + bar (d.x[i]); + d = va_arg (ap, typeof (d)); + for (i = 0; i < size; i++) + bar (d.x[i]); + va_end (ap); +} + +int main (void) +{ + int z = 5; + struct { char a[z]; } x, y; + + x.a[0] = '0'; + x.a[1] = '1'; + x.a[2] = '2'; + x.a[3] = '3'; + x.a[4] = '4'; + y.a[0] = '5'; + y.a[1] = '6'; + y.a[2] = '7'; + y.a[3] = '8'; + y.a[4] = '9'; + foo (z, x, y); + exit (0); +} -- cgit v1.2.3
