    • combine: Fix PR83304 · b1cf8293 
      In PR83304 two insns are combined, where the I2 uses a register that
has a REG_DEAD note on an insn after I2 but before I3.  In such a case
move_deaths should move that death note.  But move_deaths only looks
at the reg_stat[regno].last_death insn, and that field can be zeroed
out (previously, use_crosses_set_p would prevent the combination in
this case).

If the last_death field is zero it means "unknown", not "no death", so
we have to find if there is a REG_DEAD note.

    • [arm] PR target/83206: Make native driver select fp-capable armv6 cores · 801840e1 
      A quirk in the historical naming of some ARMv6 products means that the
main CPU name implies the presence or otherwise of the floating point unit.
This causes problems when using -mfpu=auto with -mcpu=native: the driver is
picking a CPU that does not support a floating-point unit, even though
one may well exist.

This patch addresses this by selecting the FP-capable names so that FP
instructions will be generated if the other options suggest this is
permitted.

Note that a more complete fix is really needed here to look up the
FP/simd capabilities and append the appropriate capability extensions.
This will be the subject of some follow-up patches.

	* config/arm/driver-arm.c (arm_cpu_table): Use fp-capable product names
	for armv6 ARM CPU IDs.

    • [arm] Don't strip off all architecture features from -march passed to assembler · 24531cd6 
      When GCC invokes the assembler it generates a sanitized version of the
user-specified -march option to pass through, since the assembler does
not understand all the new FPU-related architectural options.
Unfortunately it goes too far and strips off all the architectural
extensions, including some that are unrelated to the -mfpu variant
selected.

Again, this doesn't really matter when compiling C code because the
compiler will override the command-line specified architecture with
directives in the assembly file itself, but when using the compiler
driver to invoke the assembler the only indiciation of the desired
architecture might come from the command line.

We fix this by adjusting the canonicalization pass to remove any
option that only specifies features that can be expressed by -mfpu
(any that go beyond that are already supported by the assembler).  We
do have to take care to re-order the options, though as the assembler
expects feature options to be in a canonical order (unlike the
compiler, where ordering is handled left-to-right: there's only a
difference if there are negation options, but a canonicalized
architecture string shouldn't have any of those).  We do this by
recording which options we need and then sorting the final list
alphabetically.

	* common/config/arm/arm-common.c: Include <algorithm>.
	(INCLUDE_VECTOR): Define.
	(compare_opt_names): New function.
	(arm_rewrite_selected_arch): Only strip out extensions that can be
	expressed through -mfpu.  Sort the remaining extensions
	alphabetically.

    • [arm] Generate a -mfpu= option for passing to the assembler · 940269b6 
      When gcc runs with the new -mfpu=auto option (either explicitly or
when that's the default behaviour) then this option is not passed
through to the assembler as we cannot rely on the assembler
understanding it (currently it doesn't understand it at all, but in
future that might change).  That means that the assembler falls back
to its builtin default, which may not correspond to what the user
expected based on the command-line options they passed.

Normally that wouldn't matter because assembler files generated by the
compiler will contain explicit directives that set the FPU type
directly and override any internal defaults; but when the compiler
driver is used to invoke the assembler directly (because the source
file ends in .s or .S) then this might cause a problem if that assumes
the FPU matches the compiler.

To address this, this patch makes the driver construct a -mfpu= option
for the assembler in the same way as the compiler generates an
internal .fpu directive.  As mentioned, this makes no difference if
the assembler file explicitly overrides the command line options, but
helps in the case where this is implicit.


	* config/arm/arm.h (arm_asm_auto_mfpu): Declare.
	(ASM_CPU_SPEC_FUNCTIONS): Add new rule asm_auto_mfpu.
	(ASM_CPU_SPEC): Use it if -mfpu is set to auto.
