From d242afdf7e603f7fb746f98df5ded34e629e3567 Mon Sep 17 00:00:00 2001 From: Oliver Schmidt Date: Sat, 27 Jul 2013 17:21:07 +0200 Subject: [PATCH] Added sprintf() test contributed by Ullrich von Bassewitz. Comment from the author: Some may remember that there was a problem with printf reported a long time ago. I got curious and over the weekend, I wrote a program to test printf. Or better: The underlying formatting code, which is used for the whole printf() family of functions including cprintf and sprintf. The result is what made me say "oops": The program tests 377 different conversions. The cc65 printf implementation fails in 144 cases. In 31 of these cases, it fails so badly that it outputs screens of garbage, or even crashes the machine, so I had to disable these tests to proceed. Please note that you can compile the code with gcc for x86, but it will show failures. This is because the expected results are hardcoded and the integer sizes of gcc are different, so the conversion results won't match the ones expected in the code. --- testcode/lib/sprintf-test.c | 577 ++++++++++++++++++++++++++++++++++++ 1 file changed, 577 insertions(+) create mode 100644 testcode/lib/sprintf-test.c diff --git a/testcode/lib/sprintf-test.c b/testcode/lib/sprintf-test.c new file mode 100644 index 000000000..36fd4f4a5 --- /dev/null +++ b/testcode/lib/sprintf-test.c @@ -0,0 +1,577 @@ +#include +#include +#include +#if defined(__CC65__) +#include +#endif + + +/* Flag to #ifdef the tests out that crash the old implementation */ +/*#define NOCRASH 1 */ + + + +/*****************************************************************************/ +/* Code */ +/*****************************************************************************/ + + + +/* Struct used to test the 'n' conversion specifier.
