What does "word" mean here? Is it a 32-bit entity or is it according to
word_mode which is QImode for avr?
The latter, it is machine-dependent.
So the same should be true for QI-subregs of scalar modes if
UNITS_PER_WORT = 1. Right?
Right.
Thanks for that definite clarification.
As I understand PR46779 and PR45291 no longer an AVR port bugs.
And the following comment is not a true anymore:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45291#c2
Am I right ?
At least the analysis I gave there is incorrect.
I remember a problem in avr backend concerning the frame pointer because
QImode was allowed in FP's hard regs... that sort of problem. Was that
fixed here or just in some distribution like WinAVR? So perhaps it's
still this FP problem?
