http://gcc.gnu.org/bugzilla/attachment.cgi?id=27597 is a somewhat reduced test
case, which still fails with the "first bundle" (build provided by
Georg-Johann, which did not contain the patch for
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53595 yet).
It fails at my place even if
#define CODE32 ""
.
As I said in
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=963618#963618
, the register variables are instrumental - in this particular case, after
removing variable "blocking" r4 and r5 the example compiles.
The "second bundle" (contain the patch for
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53595) again compiles the example
code OK.
I also tried to clobber the r31:r30 (i.e. Z) register pair in the inline asm by
adding an output parameter with constraint "z" and removing the explicit
clobbers; in that case the example code does compile OK.
