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/cpp/trad/recurse-3.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/trad/recurse-3.c (limited to 'gcc/testsuite/gcc.dg/cpp/trad/recurse-3.c') diff --git a/gcc/testsuite/gcc.dg/cpp/trad/recurse-3.c b/gcc/testsuite/gcc.dg/cpp/trad/recurse-3.c new file mode 100644 index 000000000..91485ae5f --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/trad/recurse-3.c @@ -0,0 +1,25 @@ +/* Tests that macros that look recursive but are not are accepted. */ + +/* { dg-do preprocess } */ + +#define g(x) x +g(g(g(g(g(g(g)))))); /* { dg-bogus "detected recursion" } */ + +/* This macro gets longer with each loop, to thwart tests for + recursion based on length. */ +#define f(a,b,c,d,e,f,g,h,i) a(b,c,d,e,f,g,h,i,2 3 4 5) +f(f,f,f,f,f,f,f,f,f) /* { dg-bogus "detected recursion" } */ + +/* The above cases should be enough, but this is taken from cccp + sources so let's try it too. */ +#define foo(x,y) bar (x (y,0), y) +foo (foo, baz); /* { dg-bogus "detected recursion" } */ + +#define mac mac/**/ro +mac /* { dg-bogus "detected recursion" } */ + +#define mac2 mac2 +"mac2" /* { dg-bogus "detected recursion" } */ + +#define macro "macro +macro mac2 /* { dg-bogus "detected recursion" } */ -- cgit v1.2.3
