From 8b42b08a1bce2899c0f66ce66ef5fc75745c8f38 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Mon, 7 Nov 2016 16:19:30 +0100 Subject: [PATCH 10/17] S390: Fix build error with gcc6 in utf8_utf16-z9.c. upstream commit 808d70228891ab4d4795ab3dd1e015bf63ba18d6 This patch fixes the build error with gcc6: array subscript is above array bounds [-Werror=array-bounds] While including loop.c to construct the SINGLE(LOOPFCT) method for converting from UTF-16 to UTF-8, the bytebuf array with length MAX_NEEDED_INPUT is used as inptr. MAX_NEEDED_INPUT defaults to MIN_NEEDED_INPUT if not defined before including loop.c. Thus bytebuf has a length of 2. This patch defines MAX_NEEDED_INPUT to MAX_NEEDED_TO, which is 4. ChangeLog: * sysdeps/s390/s390-64/utf8-utf16-z9.c (MAX_NEEDED_INPUT): New define. (MAX_NEEDED_OUTPUT): New define. --- sysdeps/s390/s390-64/utf8-utf16-z9.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/sysdeps/s390/s390-64/utf8-utf16-z9.c b/sysdeps/s390/s390-64/utf8-utf16-z9.c index 6dad1c2..590a149 100644 --- a/sysdeps/s390/s390-64/utf8-utf16-z9.c +++ b/sysdeps/s390/s390-64/utf8-utf16-z9.c @@ -183,6 +183,7 @@ gconv_end (struct __gconv_step *data) #define MIN_NEEDED_INPUT MIN_NEEDED_FROM #define MAX_NEEDED_INPUT MAX_NEEDED_FROM #define MIN_NEEDED_OUTPUT MIN_NEEDED_TO +#define MAX_NEEDED_OUTPUT MAX_NEEDED_TO #define LOOPFCT FROM_LOOP /* The software implementation is based on the code in gconv_simple.c. */ #define BODY \ @@ -340,6 +341,7 @@ gconv_end (struct __gconv_step *data) /* Conversion from UTF-16 to UTF-8. */ #define MIN_NEEDED_INPUT MIN_NEEDED_TO +#define MAX_NEEDED_INPUT MAX_NEEDED_TO #define MIN_NEEDED_OUTPUT MIN_NEEDED_FROM #define MAX_NEEDED_OUTPUT MAX_NEEDED_FROM #define LOOPFCT TO_LOOP -- 1.8.3.1
