so duplicating an inline for example in the case we split a function
and then
inline both parts or in the case we inline a IPA-CP forwarder and the
specific
clone. It's not obvious what we should do here since of course for a
recursive
function we can have a function inlined two times in a row
Currently, if a warning references a cloned function, the name of the cloned
function will be emitted in the "In function 'xyz'" part of the diagnostic,
which users aren't supposed to see. This patch follows the DECL_ORIGIN link
to get the name of the original function, so the internal compiler det

Yes, this pattern should not be hit by design, and any changes to the layout of
pattern may result in
some vwsll autovec failure.

Neither that link nor another one the page it points to (which is in

There were two identical definitions, and none of them are available
where they are needed for implementing __lengthof__. Merge them, and
provide the single definition in gcc/tree.{h,cc}, where it's available
for __lengthof__, which will be added in the following commit.
gcc/ChangeLog:
*
This operator is similar to sizeof but can only be applied to an array,
and returns its length (number of elements).
FUTURE DIRECTIONS:
- We should make it work with array parameters to functions,
and somehow magically return the length designator of the array,
regardless of it being reall
The old name was misleading.
While at it, also rename some temporary variables that are used with
this function, for consistency.

This is really great how thoroughly you documented all these changes -
Per codingconventions.html as a noun we use "runtime" as opposed to
"run-time".

I became aware of a typo in this paragraph and then realized there is more

For QI/HImode of .SAT_ADD, the operands may be sign-extended and the
high bits of Xmode may be all 1 which is not expected. For example as
below code.

signed char *d = b;

A bit of bikeshedding:
While it's obviously a bug, I'm not really sure it's useful to truncate before
emitting the widening shift. Do we save an instruction vs. the regular

This patch would like to fix one ICE when rv64gcv_zvbb for vwsll.
Consider below example.
void vwsll_vv_test (short *restrict dst, char *restrict a,
int *restrict b, int n)
{
for (int i = 0; i < n; i++)
dst[i] = a[i] << b[i];
}
It will hit the vwsll patter

I noticed this has not been pushed yet and believe Wilken does not have

This makes sense to me, and the documentation is fine (with "latter"
