Hi!
The following testcase ICEs because BITINT_TYPE isn't handled in
type_contains_placeholder_1. Given that Ada doesn't emit it, it doesn't
matter that much where exactly we handle it as right now it should never
contain a placeholder; I've picked the same spot as INTEGER_TYPE, but if

The current implementation calls __detail::__modulo which is relatively

A better implementation is possible if we assume that x.ok() && y.ok() == true,
so that n = x.c_encoding() - y.c_encoding() is in [-6, 6]. In this case, it
suffices to return n >= 0 ? n : n + 7.

Cool thanks ! ;)

Ping!
please review.

Subject: [PATCH v4] RISC-V: vsetvl: Refine REG_EQUAL equality.
This patch enhances the equality check for REG_EQUAL notes in the vsetvl

I would prefer you suppress those patterns in riscv.cc rather than
adjust the including order, T-Head extension goes that way too, so I
would prefer to keep it using a consistent way.

This fixes a bunch more tests that try to override the default architecture;
some partially used the framework for doing this, others just blindly
added a -march option, which was doomed to cause problems. In most cases
we can now run these tests regardless of the users testing options and
the ba
This test is arm specific and requires neon. To improve compatibility
add a new test for armv7-a with neon and use that.
gcc/testsuite:
* lib/target-supports.exp (v7a_neon): New feature-test target.
* gcc.dg/debug/pr57351.c: Use it.

Add +fp to the architecture specification, so that -mfpu=auto works
with the hard-float ABI.

This test is specific to armv7m cores which do not support hardware
floating-point. We can improve its compatibility by having the default
options for this core specify -mfloat-abi=soft.

* lib/target-supports.exp (check_effective_target_arm_arch_FUNC_ok):

Convert these tests to use dg-add-options for increased compatibilty.
Since they also result in an empty translation unit, override the
default testsuite options.

dg-add-options.
* gcc.target/arm/m
Some of the standard Arm architecture tests require the test to use a
specific instruction set (arm or thumb). But although the framework
was checking that the flag was accepted, it wasn't checking that the
flag wasn't somehow being override (eg by run-specific options). We
can improve these tes
This test was explicitly setting the architecture on the command-line and
in the body of the test. In both cases this causes problems with the auto
FPU setting. Fix by using the testsuite infrastructure correctly and by
adding +fp to the pragma.

* gcc.target/arm/pragma_a
Another case where we can make better use of the infrastructure to
improve the compatibility of this test.

Use dg-require-effective-target/dg-add-options to improve

These tests use pragmas adn attributes to change the architecture.
Sometimes they simply add a feature using "+crc", but other times they
try to completely reset the architecture using "arch=armv8-a+crc".
The latter fails on a hard-float ABI with -mfpu=auto because it also
clears the FP capability
This test overrides the architecture, but fails to specify the
floating point architecture. This causes problems if -mfpu=auto is
used.

specification.
---
gcc/testsuite/gcc.target/arm/lto/pr96939_1.c
This test overrides the architecture, but fails to describe which
floating-point features are needed. This causes problems if the ABI
requires FP for parameter passing and -mfpu=auto is selected, so ensure
that one is specified.
gcc/testsuite:
* gcc.target/arm/attr-crypto.c: Add +simd t
These tests deliberately pass invalid option combinations to check
that the compiler is generating the correct diagnostic. Nevertheless,
we can improve their compatibility with other testsuite options. For
optional_thumb-1.c we use a soft-float ABI, while for
optional_thumb2.c we use arm_arch_v7
Fix another test that was trying to set the architecture directly
rather than using the infrastructure as intended.
