Hello,
there seems to be a gcc problem with the target 'sh-elf':

So your fix also applies there. Note that traditional sh memory move instructions can also have a length of 2 so your fix is conservative (but not more than the previous code). Shouldn't the new 4 bytes instructions be described latter with a new memory constraint ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31403 ^ permalink raw reply [flat|nested] 10+ messages in thread

So your fix also applies there. Ah, thanks! I'll add movsf_ie part when I return to this problem. > Shouldn't the new 4 bytes instructions be described latter with a new memory constraint ? Maybe, though I'm not sure if it's worth to effort. Of course, it'd be interesting to collect some numbers with such a change. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31403 ^ permalink raw reply [flat|nested] 10+ messages in thread

Which version of gcc do you use for source? gcc 4.4.5 20101112 (Red Hat 4.4.5-2) looks your host compiler. If you use gcc-4.4.5 as a source for sh-elf cross compiler, it has the fix in #6. In that case, even you've got the strictly same error messages in the original report against newlib's vfprintf.c, it would be a different problem. ^ permalink raw reply [flat|nested] 10+ messages in thread
