Modern processors has multiple way instruction decoders
For x86, icelake/zen3 has 5 uops, so for small loop with <= 4
instructions (usually has 3 uops with a cmp/jmp pair that can be
macro-fused), the decoder would have 2 uops bubble for each iteration
and the pipeline could not be fully utilized.
Therefore, this patch enables loop unrolling for small size loop at O2
to fullfill the decoder as much as possible. It turns on rtl loop
unrolling when targetm.loop_unroll_adjust exists and O2 plus speed only.
In x86 backend the default behavior is to unroll small loops with less
than 4 insns by 1 time.
This improves 548.exchange2 by 9% on icelake and 7.4% on zen3 with
0.9% codesize increment. For other benchmarks the variants are minor
and overall codesize increased by 0.2%.
The kernel image size increased by 0.06%, and no impact on eembc.
gcc/ChangeLog:
* common/config/i386/i386-common.cc (ix86_optimization_table):
Enable small loop unroll at O2 by default.

This patch adds a new -Wanalyzer-tainted-assertion warning to
-fanalyzer's "taint" mode (which also requires -fanalyzer-checker=taint).
It complains about attacker-controlled values being used in assertions,
or in any expression affecting control flow that guards a "noreturn"
function. As noted in the docs part of the patch, in such cases:
- when assertion-checking is enabled: an attacker could trigger
a denial of service by injecting an assertion failure
- when assertion-checking is disabled, such as by defining NDEBUG,
an attacker could inject data that subverts the process, since it
presumably violates a precondition that is being assumed by the code.
For example, given:
#include <assert.h>
int __attribute__((tainted_args))
test_tainted_assert (int n)
{
assert (n > 0);
return n * n;
}
compiling with
-fanalyzer -fanalyzer-checker=taint
gives:
t.c: In function 'test_tainted_assert':
t.c:6:3: warning: use of attacked-controlled value in condition for assertion [CWE-617] [-Wanalyzer-tainted-assertion]

The testcases have various examples for BUG and BUG_ON from the
Linux kernel; there, the diagnostic treats "panic" as an assertion
failure handler, due to '__attribute__((__noreturn__))'.

The strength-reduction implementation in expmed.cc will assess the
profitability of using shift-and-add using a RTL expression that wraps
a MULT (with a power-of-2) in a PLUS. Unless the RISC-V rtx_costs
function recognizes this as expressing a sh[123]add instruction, we
will return an inflated cost---thus defeating the optimization.
This change adds the necessary idiom recognition to provide an
accurate cost for this for of expressing sh[123]add.
Instead on expanding to
li a5,200
mulw a0,a5,a0
with this change, the expression 'a * 200' is sythesized as:
sh2add a0,a0,a0 // *5 = a + 4 * a
sh2add a0,a0,a0 // *5 = a + 4 * a
slli a0,a0,3 // *8
gcc/ChangeLog:

During the Sphinx-migration development, I used
SPHINX_BUILD='' in order to skip building info and manual
pages in gcc folder. However, we've got HAS_SPHINX_BUILD
which is the correct flag for that.
With the patch, one will get a nicer error message when
sphinx-build is missing and one builds (explicitly) a target which
depends on it.

For the future, we can use https://sphinx-fortran.readthedocs.io/ for
Fortran functions which can have optional arguments. However, it's an
additional dependency.

foperator_abs::op1_range works except for the NaN handling,
from:
[frange] double [-Inf, 1.79769313486231570814527423731704356798070567525844996599e+308 (0x0.fffffffffffff8p+1024)]
lhs it computes r
[frange] double [-1.79769313486231570814527423731704356798070567525844996599e+308 (-0x0.fffffffffffff8p+1024), 1.79769313486231570814527423731704356798070567525844996599e+308
+(0x0.fffffffffffff8p+1024)] +-NAN
which is correct except for the +-NAN part.
For r before the final step it makes sure to add -NAN if there is +NAN
in the lhs range, but the final r.union_ makes it unconditional +-NAN,
because the frange ctor sets +-NAN.
So, I think we need to clear it (or have some set variant which
says not to set NAN).
This patch fixes that, but isn't enough to fix the PR, something in
the assumptions handling is still broken (and the PR has other parts).

A comment in D2552R1:
"The only questionable (but still conforming) case we found was
[[carries_dependency(some_argument)]] on GCC, where the emitted diagnostic said that the
carries_dependency attribute is not supported, but did not specifically call out the syntax error
in the argument clause."
made me try the following patch, where we'll error at least
for arguments to the attribute and for some uses of the attribute
appertaining to something not mentioned in the standard warn
with different diagnostics (or should that be an error?; clang++
does that, but I think we never do for any attribute, standard or not).
The diagnostics on toplevel attribute declaration is still an
attribute ignored warning and on empty statement different wording.
The paper additionally mentions
struct X { [[nodiscard]]; }; // no diagnostic on GCC
and 2 cases of missing diagnostics on [[fallthrough]] (guess I should
file a PR about those; one problem is that do { ... } while (0); there
is replaced during genericization just by ... and another that
[[fallthrough]] there is followed by a label, but not user/case/default
label, but an artificial one created from while loop genericization.

The test fails when long is 32-bit rather than 64-bit (say x86_64 with
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} tree-ssa.exp=pr107541.c'
).
I've tweaked it to use long long so it passes even on the 32-bit
targets, and added an early out for weirdo targets because I think
the test assumes the usual 1/2/4/8 bytes sizes for char/short/int/long long.
