2020-04-08cselib, reload: Fix cselib ICE on m68k/microblaze [PR94526]Jakub Jelinek1-2/+3
The following testcase ICEs on m68k (and another one Jeff mailed me privately on microblaze). The problem is that reload creates two DEBUG_INSNs with the same value of (plus:P (reg:P sp) (const_int 0)), we compute correctly the same hash value for them, but then don't find them in the cselib hash table, as rtx_equal_for_cselib_1 thinks it is different from (reg:P sp), and trigger an assertion failure that requires that from two different debug insns one doesn't add locations to VALUEs. The patch has two fixes for this, each fixes the ICE on both targets separately, but I think we want both. The cselib.c change ensures that rtx_equal_for_cselib_1 considers (value:P sp_derived_value) and (plus:P (reg:P sp) (const_int 0)) equivalent. The reload1.c change makes sure we don't create those bogus plus 0 expressions. I understand the reasons for creating them, but they don't really apply to DEBUG_INSNs; we don't have validity matching there, all we care is that the expressions aren't arbitrarily deep, but it is just fine to fold x + 0 into just x in there. 2020-04-08 Jakub Jelinek <jakub@redhat.com> PR middle-end/94526 * cselib.c (autoinc_split): Handle e->val_rtx being SP_DERIVED_VALUE_P with zero offset. * reload1.c (eliminate_regs_1): Avoid creating (plus (reg) (const_int 0)) in DEBUG_INSNs. * gcc.dg/pr94526.c: New test.

2019-10-01Remove clobber_highRichard Sandiford1-16/+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.

2019-09-30Remove global call sets: reload.cRichard Sandiford1-32/+6
The inheritance code in find_equiv_reg can use clobbers_reg_p to test whether a call clobbers either of the equivalent registers. reload and find_reg use crtl->abi to test whether a register needs to be saved in the prologue before use. reload_as_needed can use full_and_partial_reg_clobbers and thus avoid needing to keep its own record of which registers are part call-clobbered. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * reload.c: Include function-abi.h.

2019-09-30Pass an ABI identifier to hard_regno_call_part_clobberedRichard Sandiford1-5/+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.

2019-09-10Add call_used_or_fixed_reg_pRichard Sandiford1-3/+5
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 Sandiford1-4/+4
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.

2019-06-19Simplify setjmp and non-local goto implementation (PR84521)Wilco Dijkstra1-90/+0
This fixes and simplifies the setjmp and non-local goto implementation. Currently the virtual frame pointer is saved when using __builtin_setjmp or a non-local goto. Depending on whether a frame pointer is used, this may either save SP or FP with an immediate offset. However the goto or longjmp always updates the hard frame pointer. A receiver veneer in the original function then assigns the hard frame pointer to the virtual frame pointer, which should, if it works correctly, again assign SP or FP. However the special elimination code in eliminate_regs_in_insn doesn't do this correctly unless the frame pointer is used, and even if it worked by writing SP, the frame pointer would still be corrupted. A much simpler implementation is to always save and restore the hard frame pointer. This avoids 2 redundant instructions which add/subtract the virtual frame offset. A large amount of code can be removed as a result, including all implementations of TARGET_BUILTIN_SETJMP_FRAME_VALUE (all of which already use the hard frame pointer). The expansion of nonlocal_goto on PA can be simplied to just restore the hard frame pointer. This fixes the most obvious issues, however there are still issues on targets which define HARD_FRAME_POINTER_IS_FRAME_POINTER (arm, mips). Each function could have a different hard frame pointer, so a non-local goto may restore the wrong frame pointer (TARGET_BUILTIN_SETJMP_FRAME_VALUE could be useful for this). The i386 TARGET_BUILTIN_SETJMP_FRAME_VALUE was incorrect: if stack_realign_fp is true, it would save the hard frame pointer value but restore the virtual frame pointer which according to ix86_initial_elimination_offset can have a non-zero offset from the hard frame pointer. The ia64 implementation of nonlocal_goto seems incorrect since the helper function moves the the frame pointer value into the static chain register (so this patch does nothing to make it better or worse).

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-10/+11
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.

2017-12-12[SFN] boilerplate changes in preparation to introduce nonbind markersAlexandre Oliva1-2/+2
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.

2017-10-26Add wider_subreg_mode helper functionsRichard Sandiford1-15/+17
This patch adds helper functions that say which of the two modes involved in a subreg is the larger, preferring the outer mode in the event of a tie.

2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford1-1/+1
I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the version that was in most header files, since the one in the manual seemed less clear. The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in microblaze_starting_frame_offset; this seems to be a port-local convention and takes advantage of the fact that FIRST_PARM_OFFSET doesn't read FNDECL. 2017-10-23 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (starting_frame_offset): New hook. * doc/tm.texi (STARTING_FRAME_OFFSET): Remove in favor of...

The reload use (and the LRA one that was based on it) seemed to ignore the BYTES_BIG_ENDIAN != WORDS_BIG_ENDIAN case; it's not obvious whether that was deliberate or an oversight. 2017-10-22 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * lra-spills.c (assign_mem_slot): Use subreg_size_lowpart_offset. * regcprop.c (maybe_mode_change): Likewise. * reload1.c (alter_reg): Likewise.

2017-09-05Make more use of int_mode_for_sizeRichard Sandiford1-10/+12
This patch converts more places that could use int_mode_for_size instead of mode_for_size. This is in preparation for an upcoming patch that makes mode_for_size itself return an opt_mode. require () seems like the right choice in expand_builtin_powi because we have got past the point of backing out. We go on to do: op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL); if (GET_MODE (op1) != mode2) op1 = convert_to_mode (mode2, op1, 0); which would be invalid for (and have failed for) BLKmode. In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange, the possible bitsizes are {8, 16, 32, 64, 128}, all of which give target-independent integer modes (up to TImode). The comment above the call in get_builtin_sync_mode makes clear that an integer mode must be found. We can use require () in expand_builtin_atomic_clear and expand_builtin_atomic_test_and_set because there's always an integer mode for the boolean type. The same goes for the POINTER_SIZE request in layout_type. Similarly we can use require () in combine_instructions and gen_lowpart_common because there's always an integer mode for HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and HOST_BITS_PER_DOUBLE_INT (TImode). The calls in aarch64_function_value, arm_function_value, aapcs_allocate_return_reg and mips_function_value_1 are handling cases in which a big-endian target passes or returns values at the most significant end of a register. In each case the ABI constrains the size to a small amount and does not handle non-power-of-2 sizes wider than a word. The calls in c6x_expand_movmem, i386.c:emit_memset, lm32_block_move_inline, microblaze_block_move_straight and mips_block_move_straight are dealing with expansions of block memory operations using register-wise operations, and those registers must have non-BLK mode. The reason for using require () in ix86_expand_sse_cmp, mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and spu_emit_branch_and_set is that we go on to emit non-call instructions that use registers of that mode, which wouldn't be valid for BLKmode. 2017-09-05 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * builtins.c (expand_builtin_powi): Use int_mode_for_size.

2017-09-04Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hookRichard Sandiford1-4/+6
The SVE patches change the size of a machine_mode from a compile-time constant to a runtime invariant. However, target-specific code can continue to treat the modes as constant-sized if the target only has constant-sized modes. The main snag with this approach is that target-independent code still uses macros from the target .h file. This patch is one of several that converts a target macro to a hook. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * target.def (hard_regno_call_part_clobbered): New hook. * doc/tm.texi.in (HARD_REGNO_CALL_PART_CLOBBERED): Replace with...
