Hi!
Earlier in the simplification pattern, we require that @0 has compatible
type to the type of IMAGPART_EXPR, but for @1 which is a non-zero constant
all we require is that it the constant fits into that type.
Later the code checks if the constant is negative, because when min / max

Hi!
On the following testcase, we only optimize bar where this optimization
is performed at GENERIC folding time, but on GIMPLE it doesn't trigger

Kito,
Looks like this series fell by the wayside (possibly, because it
didn't have a cover-letter and was easier to miss)?
Thanks,

Hi All,
The usdot operation is common in video encoder and decoders including some of
the most widely used ones.

Hi All,
For IEEE 754 floating point formats we can replace a sequence of alternative
+/- with fneg of a wider type followed by an fadd. This eliminated the need for
using a permutation. This patch adds a math.pd rule to recognize and do this
rewriting.
For

Hi All,
This adds a match.pd rule that drops the bitwwise nots when both arguments to a
subtract is inverted. i.e. for:
float g(float a, float b)
{
return ~(int)a - ~(int)b;
}
we instead generate
float g(float a, float b)
{
return (int)a - (int)b;
}
We already do a limited version of this

uint8_t xk;

Hi All,
This optimizes the following sequence
((a < b) & c) | ((a >= b) & d)
into
(a < b ? c : d) & 1
for scalar. On vector we can omit the & 1.
This changes the code generation from

cmp w0, w1
csetw0, lt
csetw1, ge

Hi,
I just noticed -fdump-statistics supports asmname sub-option, which
according to the doc states:
"If DECL_ASSEMBLER_NAME has been set for a given decl, use that in the dump
instead of DECL_NAME. Its primary use is ease of use working backward from
mangled names in the assembly file."

When evaluating the LHS of a stmt, its more efficient/better to call
value_of_stmt directly rather than value_of_expr. The value_of_*
routines are not quite as efficient as the range_of routines, plus
value_of_expr will check if its a LHS, and invoke value_of_stmt if it is.
This in fact speed
When checking the results of moving the vrp1 pass to ranger, we
triggered a failure where a non-null was not being propagated properly
by the ranger inferring code.
When an ssa_name never occurs in an outgoing range in any block, it is
marked as invariant and its range is not tracked in the ca
There's no point adding no-op initializer fns (that a module might
have) to the static initializer list. Also, we can add any objc
initializer call to a partial initializer function and simplify some
control flow.

When the compiler warns about padding struct to alignment boundary, it
now also informs the user about the size of the alignment that needs to
