RE: [lwip-users] Problem With dns.c Using 32-Bit Compilers

[Grubb, Jared]

I'm working with a ARM7TDMI and it definitely has byte access (the STRB 
instruction, for example). The only case where the ARM7 could have trouble is 
if it tries to access something (a word via STR, for example) at a non-aligned 
boundary.

ARM7 and ARM9r4 do not have physical byte access, that is what I meant.
So if the compiler wants byte access, it will do whatever it takes to
get the byte, even worse to write it. If you compute pipeline misses, it
gets a mess.
