From bf05293973b348f6946c9df92cd3c65ece42d0be Mon Sep 17 00:00:00 2001 From: James Yang Date: Thu, 10 Jan 2008 16:02:07 -0600 Subject: [PATCH] Fix 64-bit vsprintf. There were some size and unsigned problems. Also add support for "ll" size modifier in format string like glibc Signed-off-by: James Yang Acked-by: Jon Loeliger --- lib_generic/vsprintf.c | 23 ++++++++++++++++++----- 1 file changed, 18 insertions(+), 5 deletions(-) diff --git a/lib_generic/vsprintf.c b/lib_generic/vsprintf.c index 2740f2e769..3db6c3f936 100644 --- a/lib_generic/vsprintf.c +++ b/lib_generic/vsprintf.c @@ -105,17 +105,26 @@ static int skip_atoi(const char **s) #define SPECIAL 32 /* 0x */ #define LARGE 64 /* use 'ABCDEF' instead of 'abcdef' */ +#ifdef CFG_64BIT_VSPRINTF #define do_div(n,base) ({ \ - int __res; \ - __res = ((unsigned long) n) % (unsigned) base; \ - n = ((unsigned long) n) / (unsigned) base; \ + unsigned int __res; \ + __res = ((unsigned long long) n) % base; \ + n = ((unsigned long long) n) / base; \ __res; \ }) +#else +#define do_div(n,base) ({ \ + int __res; \ + __res = ((unsigned long) n) % base; \ + n = ((unsigned long) n) / base; \ + __res; \ +}) +#endif #ifdef CFG_64BIT_VSPRINTF -static char * number(char * str, long long num, int base, int size, int precision ,int type) +static char * number(char * str, long long num, unsigned int base, int size, int precision ,int type) #else -static char * number(char * str, long num, int base, int size, int precision ,int type) +static char * number(char * str, long num, unsigned int base, int size, int precision ,int type) #endif { char c,sign,tmp[66]; @@ -255,6 +264,10 @@ int vsprintf(char *buf, const char *fmt, va_list args) qualifier = -1; if (*fmt == 'h' || *fmt == 'l' || *fmt == 'q') { qualifier = *fmt; + if (qualifier == 'l' && *(fmt+1) == 'l') { + qualifier = 'q'; + ++fmt; + } ++fmt; }
