3599dfbaa2 RISC-V: Include more registers in SIBCALL_REGS.
This finishes the part 1 of 2 patch submitted by Andrew Burgess on Aug 19.
This adds the argument registers but not t0 (aka x5) to SIBCALL_REGS.  It
also adds the missing riscv_regno_to_class change.

Tested with cross riscv32-elf and riscv64-linux toolchain build and check.
There were no regressions.  I see about a 0.01% code size reduction for the
C and libstdc++ libraries.

7d3b27ff12 [AArch64] Fix symbol offset limit
In aarch64_classify_symbol symbols are allowed large offsets on relocations. 
This means the offset can use all of the +/-4GB offset, leaving no offset
available for the symbol itself.  This results in relocation overflow and
link-time errors for simple expressions like &global_array + 0xffffff00.

To avoid this, unless the offset_within_block_p is true, limit the offset
to +/-1MB so that the symbol needs to be within a 3.9GB offset from its
references.  For the tiny code model use a 64KB offset, allowing most of
the 1MB range for code/data between the symbol and its references.

    gcc/
	* config/aarch64/aarch64.c (aarch64_classify_symbol):
	Apply reasonable limit to symbol offsets.

In PR70010, a function is marked with target(no-vsx) to disable VSX code
generation.  To avoid VSX code generation, this function should not be
inlined into VSX function.  To fix the bug, in the current logic when
checking whether the caller's ISA flags supports the callee's ISA flags, we
just need to add a test that enforces that the caller's ISA flags match
exactly the callee's flags, for those flags that were explicitly set in the
callee.  If caller without target attribute then using options from command
line.

550a338052 [AArch64] Add partial SVE vector modes
This patch adds extra vector modes that represent a half, quarter or
eighth of what an SVE vector can hold.  This is useful for describing
the memory vector involved in an extending load or truncating store.
It might also be useful in future for representing "unpacked" SVE
registers, i.e. registers that contain values in the low bits of a
wider containing element.

The new modes could have the same width as an Advanced SIMD mode for
certain -msve-vector-bits=N options, so we need to ensure that they
come later in the mode list and that Advanced SIMD modes always "win".

This patch adds an assert that all the individual *_adjust allocations

96eb7d7a64 Deal with incoming POLY_INT_CST ranges (PR92033)
This patch makes value_range_base::set convert POLY_INT_CST bounds
into the worst-case INTEGER_CST bounds.  The main case in which this
gives useful ranges is a lower bound of A + B * X becoming A when B >= 0.
E.g.:

  [32 + 16X, 100] -> [32, 100]
  [32 + 16X, 32 + 16X] -> [32, MAX]

But the same thing can be useful for the upper bound with negative
X coefficients.
