hello,
The documentation for -fno-branch-count-reg explains that a
dec-and-test-branch instruction is replaced by an equivalent sequence of
instruction that decrement a register, compare it against 0, and branch.
(see the use of the world *instead*)
This is not really true, since this option
Hello all,
The target that i am working on is 16bit, big endian and with 16 registers.
It has this particular addressing mode
load Rd, Ra[offset]
store Rs, Ra[offset]
where the offset should be positive, base register Ra should be an
even register and for the source or the destination register R
This regression came through just today...

Same regression, but m32c is overall better since yesterday :-)

Hello. I have some complex statement-expressions that I am having trouble with
and this seemed like the more technical mailing list. I have boiled them down
to these small examples:
#1:
#define copyof(str) ({ char buf[sizeof(str)]; strcpy(buf, str); buf; })
int main(int argc, char **argv) {
Sorry, bad proofreading. The #4 example should read:
struct copy { char buf[128]; };
#define copyof(str) &({ struct copy cp; strcpy(cp.buf, str); cp; }).buf[0]
int main(int argc, char **argv) {
printf("%s %s\n", copyof("hello"), copyof("world"));
}

I agree that turning off the 4.1 snapshots makes sense. If you're
sufficiently motivated to do the automatic

Ok.

Richard,
I appreciate the extra input.
I agree with what you say. The target should not be doing middle-end
stuff .
The inc/dec and (Rxx) != (frame pointer) parts just reload using
pointer class
which is a one extra register than base pointers but the extra reg
cannot take offset.

Thanks.
Looking back, my message sounded like I was holding you personally
responsible for the current AVR macro. Didn't mean to do that ;)
