From c00a49ecd165b2d06c1c9b249d212dc843fa116f Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Sat, 15 Mar 2014 22:08:19 -0700 Subject: [PATCH] testsuite/libffi.call/many.c: Avoid spurious failure due to excess precision The test case testsuite/libffi.call/many.c can spuriously fail due to excess floating-point precision. Instrumenting it with some printf calls shows differences well above FLT_EPSILON. (Note when instrumenting it that multiple computations of the difference, such as one in a print and another in the conditional, may produce different results.) Rather than complicating the test suite with architecture-specific flags to avoid excess precision, just simplify the floating-point computation to avoid a dependency on potential excess precision. --- testsuite/libffi.call/many.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/testsuite/libffi.call/many.c b/testsuite/libffi.call/many.c index 11818e6f..5447664f 100644 --- a/testsuite/libffi.call/many.c +++ b/testsuite/libffi.call/many.c @@ -32,7 +32,7 @@ static float many(float f1, (double) f11, (double) f12, (double) f13); #endif - return f1/f2+f3/f4+f5/f6+f7/f8+f9/f10+f11/f12+f13; + return f1+f2+f3+f4+f5+f6+f7+f8+f9+f10+f11+f12+f13; } int main (void)
