2019-11-07Support using multiple registers to hold the frame pointerKwok Cheung Yeung1-13/+20
When multiple hard registers are required to hold the frame pointer, ensure that the registers after the first are marked as non-allocatable, live and eliminable as well. 2019-11-07 Kwok Cheung Yeung <kcy@codesourcery.com> gcc/ * ira.c (setup_alloc_regs): Setup no_unit_alloc_regs for frame pointer in multiple registers.

2019-10-01Remove clobber_highRichard Sandiford1-6/+1
The AArch64 SVE tlsdesc patterns were the main motivating reason for clobber_high. It's no longer needed now that the patterns use calls instead. At the time, one of the possible future uses for clobber_high was for asm statements. However, the current code wouldn't handle that case without modification, so I think we might as well remove it for now. We can always reapply it in future if it turns out to be useful again. 2019-10-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * rtl.def (CLOBBER_HIGH): Delete. * doc/rtl.texi (clobber_high): Remove documentation. * rtl.h (SET_DEST): Remove CLOBBER_HIGH from the list of codes.

2019-09-30Make ira call df_set_regs_ever_live for extra call-clobbered regsRichard Sandiford1-9/+32
If we support multiple ABIs in the same translation unit, it can sometimes be the case that a callee clobbers more registers than its caller is allowed to. We need to call df_set_regs_ever_live on these extra registers so that the prologue and epilogue code can handle them appropriately. This patch does that in IRA. I wanted to avoid another full instruction walk just for this, so I combined it with the existing set_paradoxical_subreg walk. This happens before the first calculation of elimination offsets. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * function-abi.h (function_abi_aggregator): New class. * function-abi.cc (function_abi_aggregator::caller_save_regs): New function. * ira.c (update_equiv_regs_prescan): New function. Call set_paradoxical_subreg here rather than... (update_equiv_regs): ...here. (ira): Call update_equiv_regs_prescan. From-SVN: r276339
2019-09-30Remove global call sets: IRARichard Sandiford1-4/+2
For -fipa-ra, IRA already keeps track of which specific registers are call-clobbered in a region, rather than using global information. The patch generalises this so that it tracks which ABIs are used by calls in the region. We can then use the new ABI descriptors to handle partially-clobbered registers in the same way as fully-clobbered registers, without having special code for targetm.hard_regno_call_part_clobbered. This in turn makes -fipa-ra work for partially-clobbered registers too. A side-effect of allowing multiple ABIs is that we no longer have an obvious set of conflicting registers for the self-described "fragile hack" in ira-constraints.c. This code kicks in for user-defined registers that aren't live across a call at -O0, and it tries to avoid allocating a call-clobbered register to them. Here I've used the set of call-clobbered registers in the current function's ABI, applying on top of any registers that are clobbered by called functions. This is enough to keep gcc.dg/debug/dwarf2/pr5948.c happy. The handling of GENERIC_STACK_CHECK in do_reload seemed to have a reversed condition: for (int i = 0; i < FIRST_PSEUDO_REGISTER; i++) if (df_regs_ever_live_p (i) && !fixed_regs[i] && call_used_or_fixed_reg_p (i)) size += UNITS_PER_WORD; The final part of the condition counts registers that don't need to be saved in the prologue, but I think the opposite was intended. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * function-abi.h (call_clobbers_in_region): Declare.

2019-09-10Add call_used_or_fixed_reg_pRichard Sandiford1-1/+3
Similarly to the call_used_or_fixed_regs patch, this one replaces tests of call_used_regs[i] with call_used_or_fixed_reg_p (i). The only remaining direct uses of call_used_regs are in reginfo.c and in the conditional register usage hooks. Again, this is purely mechanical.

2019-09-10Replace call_used_reg_set with call_used_or_fixed_regsRichard Sandiford1-1/+1
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.

2019-09-09Make note_stores take an rtx_insnRichard Sandiford1-5/+5
I have a series of patches that (as a side effect) makes all rtl passes use the information collected by -fipa-ra. This showed up a latent bug in the liveness tracking in regrename.c, which doesn't take CALL_INSN_FUNCTION_USAGE into account when processing clobbers. This actually seems to be quite a common problem with passes that use note_stores; only a handful remember to walk CALL_INSN_FUNCTION_USAGE too. I think it was just luck that I saw it with regrename first. This patch tries to make things more robust by passing an insn rather than a pattern to note_stores. The old function is still available as note_pattern_stores for the few places that need it. When updating callers, I've erred on the side of using note_stores rather than note_pattern_stores, because IMO note_stores should be the default choice and we should only use note_pattern_stores if there's a specific reason. Specifically: * For cselib.c, "body" may be a COND_EXEC_CODE instead of the main insn pattern. * For ira.c, I wasn't sure whether extending no_equiv to CALL_INSN_FUNCTION_USAGE really made sense, since we don't do that for normal call-clobbered registers. Same for mark_not_eliminable in reload1.c * Some other places only have a pattern available, and since those places wouldn't benefit from walking CALL_INSN_FUNCTION_USAGE, it seemed better to alter the code as little as possible. * In the config/ changes, quite a few callers have already weeded out CALL insns. It still seemed better to use note_stores rather than prematurely optimise. (note_stores should tail call to note_pattern_stores once it sees that the insn isn't a call.) The patch also documents what SETs mean in CALL_INSN_FUNCTION_USAGE. 2019-09-09 Richard Sandiford <richard.sandiford@arm.com> gcc/ * rtl.h (CALL_INSN_FUNCTION_USAGE): Document what SETs mean.

2019-07-01Allow earlyclobbers in ira_get_dup_out_numRichard Sandiford1-20/+2
ira_get_dup_out_num punted on operands that are matched to earlyclobber outputs: /* It is better ignore an alternative with early clobber. */ else if (*str == '&') goto fail; But I'm not sure why this is the right thing to do. At this stage we've established that *all* alternatives of interest require the input to match the output, so (a) the earlyclobber can only affect other operands and (b) not tying the registers is bound to introduce a move The code was part of the initial commit and so isn't obviously related to a specific testcase. Also, I can imagine LRA makes a much better job of this situation than reload did. (Certainly SVE uses matched earlyclobbers extensively and I haven't seen any problems.) In case this turns out to regress something important: the main case that matters for SVE is the one in which all alternatives are earlyclobber. 2019-07-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * ira.c (ira_get_dup_out_num): Don't punt for earlyclobbers. Use recog_data to test for an output operand. From-SVN: r272850
2019-07-01Make ira_get_dup_out_num handle more casesRichard Sandiford1-11/+44
SVE has a prefix instruction (MOVPRFX) that acts as a move but is designed to be easily fusible with the following instruction. The SVE port therefore has lots of patterns with constraints of the form: A: operand 0: =w,?w ... operand n: 0, w where the first alternative is a single instruction and the second alternative uses MOVPRFX. Ideally we want operand n to be allocated to the same register as operand 0 in this case. add_insn_allocno_copies is the main IRA routine that deals with tied operands. It is (rightly) very conservative, and only handles cases in which we're confident about saving a full move. So for a pattern like: B: operand 0: =w,w ... operand n: 0,w we don't (and shouldn't) assume that tying operands 0 and n would save the cost of a move. But in A, the second alternative has a ? marker, which makes it more expensive than the first alternative by a full reload. So I think for copy elision we should ignore the untied operand n in the second alternative of A. One approach would be to add '*' markers to each pattern and make ira_get_dup_out_num honour them. But I think the rule applies on first principles, so marking with '*' shouldn't be necessary. This patch instead makes ira_get_dup_out_num ignore expensive alternatives if there are other alternatives that match exactly. The cheapest way of doing that seemed to be to take expensive alternatives out of consideration in ira_setup_alts, which provides a bitmask of alternatives and has all the information available. add_insn_allocno_copies is the only current user of ira_setup_alts, so no other code should be affected. If all available alternatives are disparaged or need a reload, there's not much we can do to cut them down at this stage, since it's hard to predict which operands will be reloaded and which registers will need to be spilled. An interesting case is patterns like this msp430 one: ;; Alternatives 2 and 3 are to handle cases generated by reload. (define_insn "subqi3" [(set (match_operand:QI 0 "nonimmediate_operand" "=rYs, rm, &?r, ?&r") (minus:QI (match_operand:QI 1 "general_operand" "0, 0, !r, !i") (match_operand:QI 2 "general_operand" " riYs, rmi, rmi, r")))] "" "@ SUB.B\t%2, %0 SUB%X0.B\t%2, %0 MOV%X0.B\t%1, %0 { SUB%X0.B\t%2, %0 MOV%X0.B\t%1, %0 { SUB%X0.B\t%2, %0" ) Here alternative 3 is significantly more expensive then alternative 0 (reject costs 0 and 606 respectively). But if operand 1 is an integer constant, we'll still use alternative 3 if operand 2 is an allocated register. On the other hand, if operand 1 is an integer constant but operand 2 is spilled to memory, we'll move the constant into a register and use the first alternative. So in this case, if operand 1 is a register, we should consider only the first two alternatives and thus try to tie operand 1 to operand 0 (which we didn't do previously). If operand 1 is a constant integer, we should consider at least alternatives 0, 1 and 3. We could exclude alternative 2, but I don't have any evidence that that's useful. 2019-07-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * ira.c (ira_setup_alts): If any valid alternatives have zero cost, exclude any others that are disparaged or that are bound to need a reload or spill.

2019-07-01Simplify ira_setup_altsRichard Sandiford1-28/+10
ira_setup_alts has its own code to calculate the start of the constraint string for each operand/alternative combination, but preprocess_constraints now provides that information in (almost) constant time for non-asm instructions. Using it here should speed up the common case at the cost of potentially slowing down the handling of asm statements. The real reason for doing this is that a later patch wants to use more of the operand_alternative information. 2019-07-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * ira.c (ira_setup_alts): Use preprocess_constraints to get the constraint string for each operand/alternative combo.

2019-07-01Use alternative_mask for add_insn_allocno_copiesRichard Sandiford1-10/+13
add_insn_allocno_copies and its subroutines used HARD_REG_SET to represent a bitmask of alternatives. There's not really any connection between the number of registers and the maximum number of alternatives, so this patch uses alternative_mask instead (which wasn't around when this code was added). This is just a minor clean-up making way for later patches. 2019-07-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * ira-int.h (ira_setup_alts, ira_get_dup_out_num): Use alternative_mask instead of HARD_REG_SET to represent a bitmask of alternatives. * ira.c (ira_setup_alts, ira_get_dup_out_num): Likewise. * ira-conflicts.c (add_insn_allocno_copies): Likewise.

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-2/+1
This patch changes SUBREG_BYTE from an int to a poly_int. Since valid SUBREG_BYTEs must be contained within the mode of the SUBREG_REG, the required range is the same as for GET_MODE_SIZE, i.e. unsigned short. The patch therefore uses poly_uint16(_pod) for the SUBREG_BYTE. Using poly_uint16_pod rtx fields requires a new field code ('p'). Since there are no other uses of 'p' besides SUBREG_BYTE, the patch doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE instead. The patch doesn't bother implementing 'p' support for legacy define_peepholes, since none of the remaining ones have subregs in their patterns. As it happened, the rtl documentation used SUBREG as an example of a code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1). Since there's no direct replacement for XINT, and since people should never use it even if there were, the patch changes the example to use INT_LIST instead. The patch also changes subreg-related helper functions so that they too take and return polynomial offsets. This makes the patch quite big, but it's mostly mechanical. The patch generally sticks to existing choices wrt signedness. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi: Update documentation of SUBREG_BYTE.

2017-12-20poly_int: ira subreg liveness trackingRichard Sandiford1-20/+40
Normmaly the IRA-reload interface tries to track the liveness of individual bytes of an allocno if the allocno is sometimes written to as a SUBREG. This isn't possible for variable-sized allocnos, but it doesn't matter because targets with variable-sized registers should use LRA instead. This patch adds a get_subreg_tracking_sizes function for deciding whether it is possible to model a partial read or write. Later patches make it return false if anything is variable. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * ira.c (get_subreg_tracking_sizes): New function.

This patch introduces a number of new macros and functions that will be used to distinguish between different kinds of debug stmts, insns and notes, namely, preexisting debug bind ones and to-be-introduced nonbind markers. In a seemingly mechanical way, it adjusts several uses of the macros and functions, so that they refer to narrower categories when appropriate.

2016-12-07GCC caches the whether a function is a leaf in crtl->is_leaf.Wilco Dijkstra1-5/+11
GCC caches the whether a function is a leaf in crtl->is_leaf. Using this in the backend is best as leaf_function_p may not work correctly (eg. while emitting prolog or epilog code). There are many reads of crtl->is_leaf before it is initialized. Many targets do in targetm.frame_pointer_required (eg. arm, aarch64, i386, mips, sparc), which is called before register allocation by ira_setup_eliminable_regset and sched_init. Additionally, SHRINK_WRAPPING_ENABLED calls targetm.have_simple_return, which evaluates the condition of the simple_return instruction. On ARM this results in a call to use_simple_return_p which requires crtl->is_leaf to be set correctly. To fix this, initialize crtl->is_leaf in ira_setup_eliminable_regset and early on in ira. A bootstrap did not find any uninitialized reads of crtl->is_leaf on Thumb-2. A follow-up patch will remove incorrect uses of leaf_function_p from the ARM backend. gcc/ * gcc/ira.c (ira_setup_eliminable_regset): Initialize crtl->is_leaf. (ira): Move initialization of crtl->is_leaf earlier. From-SVN: r243347
2016-11-30ira: Don't substitute into TRAP_IF insns (PR78610)Segher Boessenkool1-0/+5
In the testcase, IRA propagates a constant into a TRAP_IF insn, which then becomes an unconditional trap. Unconditional traps are control flow insns so doing this requires surgery on the cfg. We cannot do that here, so instead refuse to do the substitution.
