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/20040409-3.c | 142 +++++++++++++++++++++++ 1 file changed, 142 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20040409-3.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20040409-3.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20040409-3.c b/gcc/testsuite/gcc.c-torture/execute/20040409-3.c new file mode 100644 index 000000000..07aa99cee --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20040409-3.c @@ -0,0 +1,142 @@ +#include + +extern void abort (); + +int test1(int x) +{ + return ~(x ^ INT_MIN); +} + +unsigned int test1u(unsigned int x) +{ + return ~(x ^ (unsigned int)INT_MIN); +} + +int test2(int x) +{ + return ~(x + INT_MIN); +} + +unsigned int test2u(unsigned int x) +{ + return ~(x + (unsigned int)INT_MIN); +} + +int test3(int x) +{ + return ~(x - INT_MIN); +} + +unsigned int test3u(unsigned int x) +{ + return ~(x - (unsigned int)INT_MIN); +} + +int test4(int x) +{ + int y = INT_MIN; + return ~(x ^ y); +} + +unsigned int test4u(unsigned int x) +{ + unsigned int y = (unsigned int)INT_MIN; + return ~(x ^ y); +} + +int test5(int x) +{ + int y = INT_MIN; + return ~(x + y); +} + +unsigned int test5u(unsigned int x) +{ + unsigned int y = (unsigned int)INT_MIN; + return ~(x + y); +} + +int test6(int x) +{ + int y = INT_MIN; + return ~(x - y); +} + +unsigned int test6u(unsigned int x) +{ + unsigned int y = (unsigned int)INT_MIN; + return ~(x - y); +} + + + +void test(int a, int b) +{ + if (test1(a) != b) + abort(); + if (test2(a) != b) + abort(); + if (test3(a) != b) + abort(); + if (test4(a) != b) + abort(); + if (test5(a) != b) + abort(); + if (test6(a) != b) + abort(); +} + +void testu(unsigned int a, unsigned int b) +{ + if (test1u(a) != b) + abort(); + if (test2u(a) != b) + abort(); + if (test3u(a) != b) + abort(); + if (test4u(a) != b) + abort(); + if (test5u(a) != b) + abort(); + if (test6u(a) != b) + abort(); +} + + +int main() +{ +#if INT_MAX == 2147483647 + test(0x00000000,0x7fffffff); + test(0x80000000,0xffffffff); + test(0x12345678,0x6dcba987); + test(0x92345678,0xedcba987); + test(0x7fffffff,0x00000000); + test(0xffffffff,0x80000000); + + testu(0x00000000,0x7fffffff); + testu(0x80000000,0xffffffff); + testu(0x12345678,0x6dcba987); + testu(0x92345678,0xedcba987); + testu(0x7fffffff,0x00000000); + testu(0xffffffff,0x80000000); +#endif + +#if INT_MAX == 32767 + test(0x0000,0x7fff); + test(0x8000,0xffff); + test(0x1234,0x6dcb); + test(0x9234,0xedcb); + test(0x7fff,0x0000); + test(0xffff,0x8000); + + testu(0x0000,0x7fff); + testu(0x8000,0xffff); + testu(0x1234,0x6dcb); + testu(0x9234,0xedcb); + testu(0x7fff,0x0000); + testu(0xffff,0x8000); +#endif + + return 0; +} + -- cgit v1.2.3
