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/g++.dg/debug/debug3.C | 47 +++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/g++.dg/debug/debug3.C (limited to 'gcc/testsuite/g++.dg/debug/debug3.C') diff --git a/gcc/testsuite/g++.dg/debug/debug3.C b/gcc/testsuite/g++.dg/debug/debug3.C new file mode 100644 index 000000000..c7251429f --- /dev/null +++ b/gcc/testsuite/g++.dg/debug/debug3.C @@ -0,0 +1,47 @@ +// PR optimization/5547 +// This testcase caused ICE on IA-32, since DWARF-2 was unable +// to emit location expression for parameter a of operator+. +// { dg-do compile { target fpic } } +// { dg-options "-fpic" } + +struct A { char *s; }; + +inline A operator+ (char a, const A &b) +{ + A s; + s.s = new char[12]; + s.s[0] = a; + return s; +} + +int b (const A &); + +void test1 (const A &x, int y) +{ + int j = b ("012345"[y] + x); + for (int i = 0; i < y; i++); +} + +void test2 (const A &x, int y) +{ + int j = b ("012345678"[y + 2] + x); + for (int i = 0; i < y; i++); +} + +void test3 (const A &x, int y) +{ + int j = b ("012345678"[y - 6] + x); + for (int i = 0; i < y; i++); +} + +void test4 (const A &x, int y) +{ + int j = b ("012345678"[2 * y - 10] + x); + for (int i = 0; i < y; i++); +} + +void test5 (const A &x, int y) +{ + int j = b ("012345678"[4 * y] + x); + for (int i = 0; i < y; i++); +} -- cgit v1.2.3
