Try the '/c' modifier:
print /c foovector
x /20c &foovector

hello,
a thousand apologies if this is way too obvious and/or has been asked
many times ( i just can't find in the archives ). i am trying to debug
some mmx code in which i have declared:
__m64 foovector;
i use foovector to store 8 8bit integers(chars). now when i ask for:
print foovector
i get: { 1073836052, 1}. obviously gdb is interpreting my chars as
32bit ints. how can i tell him i just want chars ? i tried a thousand
casts like (v8qi etc...) but gdb answers "No symbol in current
context".
i am using version 6.1 on linux-x86(debian testing)
thanks in advance,
shadi
