The patch changes insn scratches which require registers for all insn alternatives (in other words w/o X constraint in scratch constraint string). This is done before IRA staring its work.

2020-09-17c-family: Macro support in -Wmisleading-indentation [PR80076]Patrick Palka1-6/+6
Currently the -Wmisleading-indentation warning doesn't do any analysis when the guarded statement or the statement after it is produced by a macro. This means we warn for: if (flag) foo (); bar (); but not for: #define BAR bar if (flag) foo (); BAR (); This patch extends the -Wmisleading-indentation implementation to support analyzing such statements and their tokens. This is done in the "natural" way by resolving the location of each of the three tokens to the token's macro expansion point. (Additionally, if the tokens all resolve to the same macro expansion point then we instead use their locations within the macro definition.) When these resolved locations are all different, then we can proceed with applying the warning heuristics to them as if no macros were involved. gcc/c-family/ChangeLog: PR c/80076 * c-indentation.c (should_warn_for_misleading_indentation): Move declarations of local variables closer to their first use.

2020-09-07lra: Avoid cycling on certain subreg reloads [PR96796]Richard Sandiford1-10/+44
This PR is about LRA cycling for a reload of the form: ---------------------------------------------------------------------------- Changing pseudo 196 in operand 1 of insn 103 on equiv [r105:DI*0x8+r140:DI] Creating newreg=287, assigning class ALL_REGS to slow/invalid mem r287 Creating newreg=288, assigning class ALL_REGS to slow/invalid mem r288 103: r203:SI=r288:SI<<0x1+r196:DI#0 REG_DEAD r196:DI Inserting slow/invalid mem reload before: 316: r287:DI=[r105:DI*0x8+r140:DI] 317: r288:SI=r287:DI#0 ---------------------------------------------------------------------------- The problem is with r287. We rightly give it a broad starting class of POINTER_AND_FP_REGS (reduced from ALL_REGS by preferred_reload_class). However, we never make forward progress towards narrowing it down to a specific choice of class (POINTER_REGS or FP_REGS). I think in practice we rely on two things to narrow a reload pseudo's class down to a specific choice: (1) a restricted class is specified when the pseudo is created This happens for input address reloads, where the class is taken from the target's chosen base register class. It also happens for simple REG reloads, where the class is taken from the chosen alternative's constraints. (2) uses of the reload pseudo as a direct input operand In this case get_reload_reg tries to reuse the existing register and narrow its class, instead of creating a new reload pseudo. However, neither occurs here. As described above, r287 rightly starts out with a wide choice of class, ultimately derived from ALL_REGS, so we don't get (1). And as the comments in the PR explain, r287 is never used as an input reload, only the subreg is, so we don't get (2): ---------------------------------------------------------------------------- Choosing alt 13 in insn 317: (0) r (1) w {*movsi_aarch64} Creating newreg=291, assigning class FP_REGS to r291 317: r288:SI=r291:SI Inserting insn reload before: 320: r291:SI=r287:DI#0 ---------------------------------------------------------------------------- IMO, in this case we should rely on the reload of r316 to narrow down the class of r278. Currently we do: ---------------------------------------------------------------------------- Choosing alt 7 in insn 316: (0) r (1) m {*movdi_aarch64} Creating newreg=289 from oldreg=287, assigning class GENERAL_REGS to r289 316: r289:DI=[r105:DI*0x8+r140:DI] Inserting insn reload after: 318: r287:DI=r289:DI --------------------------------------------------- i.e. we create a new pseudo register r289 and give *that* pseudo GENERAL_REGS instead. This is because get_reload_reg only narrows down the existing class for OP_IN and OP_INOUT, not OP_OUT. But if we have a reload pseudo in a reload instruction and have chosen a specific class for the reload pseudo, I think we should simply install it for OP_OUT reloads too, if the class is a subset of the existing class. We will need to pick such a register whatever happens (for r289 in the example above). And as explained in the PR, doing this actually avoids an unnecessary move via the FP registers too. The patch is quite aggressive in that it does this for all reload pseudos in all reload instructions. I wondered about reusing the condition for a reload move in in_class_p: INSN_UID (curr_insn) >= new_insn_uid_start && curr_insn_set != NULL && ((OBJECT_P (SET_SRC (curr_insn_set)) && ! CONSTANT_P (SET_SRC (curr_insn_set))) || (GET_CODE (SET_SRC (curr_insn_set)) == SUBREG && OBJECT_P (SUBREG_REG (SET_SRC (curr_insn_set))) && ! CONSTANT_P (SUBREG_REG (SET_SRC (curr_insn_set))))))) but I can't really justify that on first principles. I think we should apply the rule consistently until we have a specific reason for doing otherwise. gcc/ PR rtl-optimization/96796 * lra-constraints.c (in_class_p): Add a default-false allow_all_reload_class_changes_p parameter.

2020-08-27lra: Canonicalize mult to shift in address reloadsAlex Coplan1-4/+39
Inside a (mem) RTX, it is canonical to write multiplications by powers of two using a (mult) [0]. Outside of a (mem), the canonical way to write multiplications by powers of two is using (ashift). Now I observed that LRA does not quite respect this RTL canonicalization rule. When compiling gcc/testsuite/gcc.dg/torture/pr34330.c with -Os -ftree-vectorize, the RTL in the dump "281r.ira" has the insn: (set (reg:SI 111) (mem:SI (plus:DI (mult:DI (reg:DI 101 [ ivtmp.9 ]) (const_int 4 [0x4])) (reg/v/f:DI 105 [ b ])))) but LRA then proceeds to generate a reload, and we get the following non-canonical insn in "282r.reload": (set (reg:DI 7 x7 [121]) (plus:DI (mult:DI (reg:DI 5 x5 [orig:101 ivtmp.9 ] [101]) (const_int 4 [0x4])) (reg/v/f:DI 1 x1 [orig:105 b ] [105]))) This patch fixes LRA to ensure that we generate canonical RTL in this case. After the patch, we get the following insn in "282r.reload": (set (reg:DI 7 x7 [121]) (plus:DI (ashift:DI (reg:DI 5 x5 [orig:101 ivtmp.9 ] [101]) (const_int 2 [0x2])) (reg/v/f:DI 1 x1 [orig:105 b ] [105]))) [0] : https://gcc.gnu.org/onlinedocs/gccint/Insn-Canonicalizations.html gcc/ChangeLog: * lra-constraints.c (canonicalize_reload_addr): New.

2020-03-21lra: Tighten check for reloading paradoxical subregs [PR94052]Richard Sandiford1-10/+14
simplify_operand_subreg tries to detect whether the allocation for a pseudo in a paradoxical subreg is also valid for the outer mode. The condition it used to check for an invalid combination was: else if (REG_P (reg) && REGNO (reg) >= FIRST_PSEUDO_REGISTER && (hard_regno = lra_get_regno_hard_regno (REGNO (reg))) >= 0 && (hard_regno_nregs (hard_regno, innermode) < hard_regno_nregs (hard_regno, mode)) && (regclass = lra_get_allocno_class (REGNO (reg))) && (type != OP_IN || !in_hard_reg_set_p (reg_class_contents[regclass], mode, hard_regno) || overlaps_hard_reg_set_p (lra_no_alloc_regs, mode, hard_regno))) I think there are two problems with this: (1) It never actually checks whether the hard register is valid for the outer mode (in the hard_regno_mode_ok sense). If it isn't, any attempt to reload in the outer mode is likely to cycle, because the implied regno/mode combination will be just as invalid next time curr_insn_transform sees the subreg. (2) The check is valid for little-endian only. For big-endian we need to move hard_regno backwards. Using simplify_subreg_regno should avoid both problems. As the existing comment says, IRA should always take subreg references into account when allocating hard registers, so this fix-up should only really be needed for pseudos allocated by LRA itself. gcc/ 2020-03-21 Richard Sandiford <richard.sandiford@arm.com> PR rtl-optimization/94052 * lra-constraints.c (simplify_operand_subreg): Reload the inner register of a paradoxical subreg if simplify_subreg_regno fails to give a valid hard register for the outer mode. gcc/testsuite/ 2020-03-21 Tamar Christina <tamar.christina@arm.com> PR target/94052 * gcc.target/aarch64/pr94052.C: New test.

2019-11-18LRA: handle memory constraints that accept more than "m"Richard Sandiford1-6/+19
LRA allows address constraints that are more relaxed than "p": /* Target hooks sometimes don't treat extra-constraint addresses as legitimate address_operands, so handle them specially. */ if (insn_extra_address_constraint (cn) && satisfies_address_constraint_p (&ad, cn)) return change_p; For SVE it's useful to allow the same thing for memory constraints. The particular use case is LD1RQ, which is an SVE instruction that addresses Advanced SIMD vector modes and that accepts some addresses that normal Advanced SIMD moves don't. Normally we require every memory to satisfy at least "m", which is defined to be a memory "with any kind of address that the machine supports in general". However, LD1RQ is very much special-purpose: it doesn't really have any relation to normal operations on these modes. Adding its addressing modes to "m" would lead to bad Advanced SIMD optimisation decisions in passes like ivopts. LD1RQ therefore has a memory constraint that accepts things "m" doesn't. 2019-11-18 Richard Sandiford <richard.sandiford@arm.com> gcc/ * lra-constraints.c (valid_address_p): Take the operand and a constraint as argument.

2019-09-30Remove global call sets: LRARichard Sandiford1-14/+37
lra_reg has an actual_call_used_reg_set field that is only used during inheritance. This in turn required a special lra_create_live_ranges pass for flag_ipa_ra to set up this field. This patch instead makes the inheritance code do its own live register tracking, using the same ABI-mask-and-clobber-set pair as for IRA. Tracking ABIs simplifies (and cheapens) the logic in lra-lives.c and means we no longer need a separate path for -fipa-ra. It also means we can remove TARGET_RETURN_CALL_WITH_MAX_CLOBBERS. The patch also strengthens the sanity check in lra_assigns so that we check that reg_renumber is consistent with the whole conflict set, not just the call-clobbered registers. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (return_call_with_max_clobbers): Delete. * doc/tm.texi.in (TARGET_RETURN_CALL_WITH_MAX_CLOBBERS): Delete. * doc/tm.texi: Regenerate. * config/aarch64/aarch64.c (aarch64_return_call_with_max_clobbers) (TARGET_RETURN_CALL_WITH_MAX_CLOBBERS): Delete. * lra-int.h (lra_reg::actual_call_used_reg_set): Delete.

2019-09-30Pass an ABI identifier to hard_regno_call_part_clobberedRichard Sandiford1-1/+3
This patch replaces the rtx_insn argument to targetm.hard_regno_call_part_clobbered with an ABI identifier, since call insns are now just one possible way of getting an ABI handle. This in turn allows predefined_function_abi::initialize to do the right thing for non-default ABIs. The horrible ?: in need_for_call_save_p goes away in a later patch, with the series as a whole removing most direct calls to the hook in favour of function_abi operations. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (hard_regno_call_part_clobbered): Take an ABI identifier instead of an rtx_insn. * doc/tm.texi: Regenerate. * hooks.h (hook_bool_insn_uint_mode_false): Delete.

2019-09-10Replace call_used_reg_set with call_used_or_fixed_regsRichard Sandiford1-3/+3
CALL_USED_REGISTERS and call_used_regs infamously contain all fixed registers (hence the need for CALL_REALLY_USED_REGISTERS etc.). We try to recover from this to some extent with: /* Contains 1 for registers that are set or clobbered by calls. */ /* ??? Ideally, this would be just call_used_regs plus global_regs, but for someone's bright idea to have call_used_regs strictly include fixed_regs. Which leaves us guessing as to the set of fixed_regs that are actually preserved. We know for sure that those associated with the local stack frame are safe, but scant others. */ HARD_REG_SET x_regs_invalidated_by_call; Since global registers are added to fixed_reg_set and call_used_reg_set too, it's always the case that: call_used_reg_set == regs_invalidated_by_call | fixed_reg_set This patch replaces all uses of call_used_reg_set with a new macro call_used_or_fixed_regs to make this clearer. This is part of a series that allows call_used_regs to be what is now call_really_used_regs. It's a purely mechanical replacement; later patches clean up obvious oddities like "call_used_or_fixed_regs & ~fixed_regs". 2019-09-10 Richard Sandiford <richard.sandiford@arm.com> gcc/ * hard-reg-set.h (target_hard_regs::x_call_used_reg_set): Delete.

2019-07-31Make lra use per-alternative earlyclobber infoRichard Sandiford1-8/+12
lra_insn_reg and lra_operand_data have both a bitmask of earlyclobber alternatives and an overall boolean. The danger is that we then test the overall boolean when really we should be testing for a particular alternative. This patch gets rid of the boolean and tests the mask against zero when we really do need to test "any alternative might be earlyclobber". (I think the only instance of that is the LRA_UNKNOWN_ALT handling in lra-lives.c:reg_early_clobber_p.) This is needed (and tested) by an upcoming SVE patch. 2019-07-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * lra-int.h (lra_operand_data): Remove early_clobber field.
