S/390: Allow relative addressing of literal pool entries

r265490 allowed the compiler to choose in a more flexible way whether to
use load or load-address-relative-long (LARL) instruction.  When it
chose LARL for literal pool references, the latter ones were rewritten
by pass_s390_early_mach to use UNSPEC_LTREF, which assumes base register
usage, which in turn is not compatible with LARL.  The end result was an
ICE because of unrecognizable insn.

UNSPEC_LTREF and friends are necessary in order to communicate the
dependency on the base register to pass_sched2.  When relative
addressing is used, no base register is necessary, so in such cases the
rewrite must be avoided.

5 years agoarm - use the new CPU alias option to simplify the list of CPUs.
Richard Earnshaw [Fri, 9 Nov 2018 10:58:59 +0000 (10:58 +0000)]
arm - use the new CPU alias option to simplify the list of CPUs.

This patch simplifies the table of CPUs supported in GCC by making
use of the new alias feature.  Most of the changes are fairly
straight-forward:
- arm7tdmi and arm7tdmi-s are the same thing.
- arm710t, arm720t and arm740t differ only in features external to the core
- arm920 and arm920t are the same thing; arm922t and arm940t differ from
  arm920t only in features external to the core; ep9312 is an arm920t-derived
  core that we continue to recognize for legacy reasons.
- arm10tdmi and arm1020t differ only in features external to the core.
- arm9e, arm946te-s, arm966e-s and arm968e-s differ only in features external
  to the core.
- arm10e, arm1020e and arm1022e differ only in features external to the core.

The arm10e/arm1020e/arm1022e change is the only one which changes
behaviour of the compiler slightly.  Previously, and for no reason
that I can remember, the scheduler for arm1020e/arm1022e was not used
for arm10e: this was probably an oversight.  The unification means
that the same scheduler is now used for all three cores.

[PR86438] compare-elim: cope with set of in_b

resolves, we proceed to use the reg with its earlier value.  When both
resolve to the same register and prev_clobber is an insn that modifies

[PR87793] reject non-toplevel unspecs in debug loc exprs on x86

Before revision 254025, we'd reject UNSPECs in debug loc exprs.
TARGET_CONST_NOT_OK_FOR_DEBUG_P still rejects that by default, on all
ports that override it, except for x86, that accepts @gotoff unspecs.
We can indeed accept them in top-level expressions, but not as
subexpressions: the assembler rejects the difference between two
@gotoff symbols, for example.

We could simplify such a difference and drop the @gotoffs, provided
that the symbols are in the same section; we could also accept
@gotoffs plus literal constants.  However, accepting those but
rejecting such combinations as subexpressions would be ugly, and most
likely not worth the trouble: sym@gotoff+litconst hardly makes sense
as a standalone expression, and the difference between @gotoffs should
be avoided to begin with, as follows.

Ideally, the debug loc exprs would use the symbolic data in
REG_EQUIV/REG_EQUAL notes, or delegitimized addresses, instead of
simplifying the difference between two legitimized addresses so that
the occurrences of the GOT register cancel each other.  That would
require some more elaborate surgery in var-tracking and cselib than
would be appropriate at this stage.

5 years agoarm - Add support for aliases of CPU names
Richard Earnshaw [Thu, 8 Nov 2018 17:48:39 +0000 (17:48 +0000)]
arm - Add support for aliases of CPU names

This patch adds support for defining an alias for a CPU name that can
then be used in conjunction with the -mcpu option in the same way that
the primary name can be used.  Aliases do not lead to a short-cut of
the feature options; they are literally an alternative name for the
core CPU.

The new entry in arm-cpus.in allows a cpu definition to contain an
alias statement, for example

begin cpu strongarm
 alias strongarm110 !strongarm1100 !strongarm1110
 ...
end cpu strongarm

each entry in the list represents another alias for the CPU.  If the
alias name starts with an exclamation mark, then it will match as for
any other alias (sans the ! itself), but it will not be listed in any
of the CPU hinting options (the intent is to make the alias
essentially undocumented).  In the above example, hints would be
provided for strongarm and strongarm110, but not for strongarm1100 or
strongarm1110.

The advantage of using aliases in this way is that it allows us to
reduce the number of duplicate table entries and identifier tags used
inside the compiler itself.

* config/arm/parsecpu.awk (/alias/): New parsing rule.
(/begin cpu/): Check that the cpu name hasn't been previously defined.
(gen_comm_data): Print out CPU alias tables.

* config/arm/arm-protos.h (cpu_alias): New structure.

* config/arm/arm-cpus.in (strongarm): Add aliases for strongarm110

(config/arm/arm-generic.md): Remove redundant references to

* common/config/arm/arm-common.c (arm_print_hint_for_cpu_option):

(arm_parse_cpu_option_name): Also match a cpu name against the list
