2021-02-13passes: Enable split4 with selective scheduling 2 [PR98439]Jakub Jelinek1-1/+6
As mentioned in the PR, we have 5 split passes (+ splitting during final). split1 is before RA and is unconditional, split2 is after RA and is gated on optimize > 0, split3 is before sched2 and is gated on defined(INSN_SCHEDULING) && optimize > 0 && flag_schedule_insns_after_reload split4 is before regstack and is gated on HAVE_ATTR_length && defined (STACK_REGS) && !gate (split3) split5 is before shorten_branches and is gated on HAVE_ATTR_length && !defined (STACK_REGS) and the splitting during final works only when !HAVE_ATTR_length. STACK_REGS is a macro enabled only on i386/x86_64. The problem with the following testcase is that split3 before sched2 is the last splitting pass for the target/command line options set, but selective scheduling unlike normal scheduling can create new instructions that need to be split, which means we ICE during final as there are insns that require splitting but nothing split them. This patch fixes it by doing split4 also when -fselective-scheduling2 is enabled on x86 and split3 has been run. As that option isn't on by default, it should slow down compilation only for those that enable that option. 2021-02-13 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/98439 * recog.c (pass_split_before_regstack::gate): Enable even when pass_split_before_sched2 is enabled if -fselective-scheduling2 is on. * gcc.target/i386/pr98439.c: New test.
2021-01-05recog: Fix a constrain_operands corner case [PR97144]Richard Sandiford1-4/+4
aarch64's *add<mode>3_poly_1 has a pattern with the constraints: "=...,r,&r" "...,0,rk" "...,Uai,Uat" i.e. the penultimate alternative requires operands 0 and 1 to match, but the final alternative does not allow them to match. The register allocators dealt with this correctly, and so used different input and output registers for instructions with Uat operands. However, constrain_operands carried the penultimate alternative's matching rule over to the final alternative, so it would essentially ignore the earlyclobber. This in turn allowed postreload to convert a correct Uat pairing into an incorrect one. The fix is simple: recompute the matching information for each alternative. gcc/ PR rtl-optimization/97144 * recog.c (constrain_operands): Initialize matching_operand for each alternative, rather than only doing it once. gcc/testsuite/ PR rtl-optimization/97144 * gcc.c-torture/compile/pr97144.c: New test. * gcc.target/aarch64/sve/pr97144.c: Likewise.

2020-12-17recog: Add a class for propagating into insnsRichard Sandiford1-0/+380
This patch adds yet another way of propagating into an instruction and simplifying the result. (The net effect of the series is to keep the total number of propagation approaches the same though, since a later patch removes the fwprop.c routines.) One of the drawbacks of the validate_replace_* routines is that they only do simple simplifications, mostly canonicalisations: /* Do changes needed to keep rtx consistent. Don't do any other simplifications, as it is not our job. */ if (simplify) simplify_while_replacing (loc, to, object, op0_mode); But substituting can often lead to real simplification opportunities. simplify-rtx.c:simplify_replace_rtx does fully simplify the result, but it only operates on specific rvalues rather than full instruction patterns. It is also nondestructive, which means that it returns a new rtx whenever a substitution or simplification was possible. This can create quite a bit of garbage rtl in the context of a speculative recog, where changing the contents of a pointer is often enough. The new routines are therefore supposed to provide simplify_replace_rtx- style substitution in recog. They go to some effort to prevent garbage rtl from being created. At the moment, the new routines fail if the pattern would still refer to the old "from" value in some way. That might be unnecessary in some contexts; if so, it could be put behind a configuration parameter. gcc/ * recog.h (insn_propagation): New class. * recog.c (insn_propagation::apply_to_mem_1): New function.

2020-12-17recog: Add a way of temporarily undoing changesRichard Sandiford1-0/+48
In some cases, it can be convenient to roll back the changes that have been made by validate_change to see how things looked before, then reroll the changes. For example, this makes it possible to defer calculating the cost of an instruction until we know that the result is actually needed. It can also make dumps easier to read. This patch adds a couple of helper functions for doing that. gcc/ * recog.h (temporarily_undo_changes, redo_changes): Declare. * recog.c (temporarily_undone_changes): New variable.

2020-12-17recog: Add a validate_change_xveclen functionRichard Sandiford1-6/+35
A later patch wants to be able to use the validate_change machinery to reduce the XVECLEN of a PARALLEL. This should be more efficient than allocating a separate PARALLEL at a possibly distant memory location, especially since the new PARALLEL would be garbage rtl if the new pattern turns out not to match. Combine already pulls this trick with SUBST_INT. This patch adds a general helper for doing that. gcc/ * recog.h (validate_change_xveclen): Declare. * recog.c (change_t::old_len): New field. (validate_change_1): Add a new_len parameter. Conditionally replace the XVECLEN of an rtx, avoiding single-element PARALLELs. (validate_change_xveclen): New function.

The names of split_before_sched2 ("split4") and split_before_regstack ("split3") do not reflect their insertion point in the sequence of passes, where split_before_regstack follows split_before_sched2. Reorder the code and rename the passes to reflect the reality. split_before_regstack pass does not need to run if split_before_sched2 pass was already performed. Introduce enable_split_before_sched2 function to simplify gating functions of these two passes.

[PR92190] The problem is that x86 is the only target that defines HAVE_ATTR_length and doesn't schedule any splitting pass at -O0 after pro_and_epilogue. So, either we go back to handling this during vzeroupper output (unconditionally, rather than flag_ipa_ra guarded), or we need to tweak the split* passes for x86. Seems there are 5 split passes, split1 is run unconditionally before reload, split2 is run for optimize > 0 or STACK_REGS (x86) after ra but before epilogue_completed, split3 is run before regstack for STACK_REGS and optimize and -fno-schedule-insns2, split4 is run before sched2 if sched2 is run and split5 is run before shorten_branches if HAVE_ATTR_length and not STACK_REGS. 2020-02-05 Jakub Jelinek <jakub@redhat.com> PR target/92190 * recog.c (pass_split_after_reload::gate): For STACK_REGS targets, don't run when !optimize.

2019-10-01Remove clobber_highRichard Sandiford1-5/+3
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.

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.

2018-01-03poly_int: PUSH_ROUNDINGRichard Sandiford1-10/+12
PUSH_ROUNDING is difficult to convert to a hook since there is still a lot of conditional code based on it. It isn't clear that a direct conversion with checks for null hooks is the right thing to do. Rather than untangle that, this patch converts all implementations that do something to out-of-line functions that have the same interface as a hook would have. This should at least help towards any future hook conversion. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * config/cr16/cr16-protos.h (cr16_push_rounding): Declare. * config/cr16/cr16.h (PUSH_ROUNDING): Move implementation to... * config/cr16/cr16.c (cr16_push_rounding): ...this new function. * config/h8300/h8300-protos.h (h8300_push_rounding): Declare. * config/h8300/h8300.h (PUSH_ROUNDING): Move implementation to... * config/h8300/h8300.c (h8300_push_rounding): ...this new function. * config/i386/i386-protos.h (ix86_push_rounding): Declare. * config/i386/i386.h (PUSH_ROUNDING): Move implementation to... * config/i386/i386.c (ix86_push_rounding): ...this new function. * config/m32c/m32c-protos.h (m32c_push_rounding): Take and return a poly_int64. * config/m32c/m32c.c (m32c_push_rounding): Likewise. * config/m68k/m68k-protos.h (m68k_push_rounding): Declare. * config/m68k/m68k.h (PUSH_ROUNDING): Move implementation to... * config/m68k/m68k.c (m68k_push_rounding): ...this new function. * config/pdp11/pdp11-protos.h (pdp11_push_rounding): Declare. * config/pdp11/pdp11.h (PUSH_ROUNDING): Move implementation to... * config/pdp11/pdp11.c (pdp11_push_rounding): ...this new function. * config/stormy16/stormy16-protos.h (xstormy16_push_rounding): Declare. * config/stormy16/stormy16.h (PUSH_ROUNDING): Move implementation to... * config/stormy16/stormy16.c (xstormy16_push_rounding): ...this new function. * expr.c (emit_move_resolve_push): Treat the input and result of PUSH_ROUNDING as a poly_int64.

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-10/+6
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.

https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf A proposal is to introduce a target independent flag -fcf-protection=[none|branch|return|full] with a semantic to instrument a code to control validness or integrity of control-flow transfers using jump and call instructions. The main goal is to detect and block a possible malware execution through transfer the execution to unknown target address. Implementation could be either software or target based. Any target platforms can provide their implementation for instrumentation under this option. The compiler should instrument any control-flow transfer points in a program (ex. call/jmp/ret) as well as any landing pads, which are targets of control-flow transfers. A new 'nocf_check' attribute is introduced to provide hand tuning support. The attribute directs the compiler to skip a call to a function and a function's landing pad from instrumentation. The attribute can be used for function and pointer to function types, otherwise it will be ignored. Currently all platforms except i386 will report the error and do no instrumentation. i386 will provide the implementation based on a specification published by Intel for a new technology called Control-flow Enforcement Technology (CET). gcc/c-family/ * c-attribs.c (handle_nocf_check_attribute): New function.

2017-08-30[40/77] Use scalar_int_mode for extraction_insn fieldsRichard Sandiford1-14/+7
insv, extv and eztzv modify or read a field in a register or memory. The field always has a scalar integer mode, while the register or memory either has a scalar integer mode or BLKmode. The mode of the bit position is also a scalar integer. This patch uses the type system to make that explicit. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * optabs-query.h (extraction_insn::struct_mode): Change type to opt_scalar_int_mode and update comment.

2017-08-30[35/77] Add uses of as_a <scalar_int_mode>Richard Sandiford1-2/+3
This patch adds asserting as_a <scalar_int_mode> conversions to contexts in which the input is known to be a scalar integer mode. In expand_divmod, op1 is always a scalar_int_mode if op1_is_constant (but might not be otherwise). In expand_binop, the patch reverses a < comparison in order to avoid splitting a long line. gcc/ 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * cfgexpand.c (convert_debug_memory_address): Use as_a <scalar_int_mode>. * combine.c (expand_compound_operation): Likewise.
