2019-10-11Extend subst to simplify CONST_INT inside SIGN_EXTEND.Jim Wilson1-0/+1
This addresses PR 91860 which has four testcases triggering internal errors. The problem here is that in combine when handling debug insns, we are trying to substitute (sign_extend:DI (const_int 8160 [0x1fe0])) as the value for (reg:DI 78 [ _9 ]) in the debug insn (debug_insn 29 28 30 2 (var_location:QI d (subreg:QI (reg:DI 78 [ _9 ]) 0)) "tmp4.c":11:5 -1 (nil)) This eventually triggers an abort because 8160 is not a sign-extended QImode value. In subst there is already code check for a CONST_INT inside a ZERO_EXTEND and simplify it. This needs to be extended to also handle a SIGN_EXTEND the same way. gcc/ PR rtl-optimization/91860 * combine.c (subst): If new_rtx is a constant, also check for SIGN_EXTEND when deciding whether to call simplify_unary_operation. gcc/testsuite/ PR rtl-optimization/91860 * gcc.dg/pr91860-1.c: New testcase. * gcc.dg/pr91860-2.c: New testcase. * gcc.dg/pr91860-3.c: New testcase. * gcc.dg/pr91860-4.c: New testcase.

2019-10-01Remove clobber_highRichard Sandiford1-22/+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.

2019-09-30Remove global call sets: combine.cRichard Sandiford1-1/+12
There shouldn't be many cases in which a useful hard register is live across a call before RA, so we might as well keep things simple and invalidate partially-clobbered registers here, in case the values they hold leak into the call-clobbered part. In principle this is a bug fix for TARGET_HARD_REGNO_CALL_PART_CLOBBERED targets, but in practice it probably doesn't make a difference. 2019-09-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * combine.c: Include function-abi.h. (record_dead_and_set_regs): Use insn_callee_abi to get the ABI of the target of call insns. Invalidate partially-clobbered registers as well as fully-clobbered ones. From-SVN: r276316
2019-09-09Make note_stores take an rtx_insnRichard Sandiford1-8/+7
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.

Two fixes for UB when handling very large offsets. The calculation in force_int_to_mode would have been correct if signed integers used modulo arithmetic, so just switch to unsigned types. The calculation in rtx_addr_can_trap_p_1 didn't handle overflow properly, so switch to known_subrange_p instead (which is supposed to handle all cases). 2019-04-18 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/85164 * combine.c (force_int_to_mode): Cast the argument rather than the result of known_alignment. * rtlanal.c (rtx_addr_can_trap_p_1): Use known_subrange_p. gcc/testsuite/ PR middle-end/85164 * gcc.dg/pr85164-1.c, gcc.dg/pr85164-2.c: New tests.

2019-04-15combine: Count auto_inc properly (PR89794)Segher Boessenkool1-18/+42
The code that checks if an auto-increment from i0 or i1 is not lost is a bit shaky. The code to check the same for i2 is non-existent, and cannot be implemented in a similar way at all. So, this patch counts all auto-increments, and makes sure we end up with the same number as we started with. This works because we still have a check that we will not duplicate any. We should do this some better way, but not while we are in stage 4. PR rtl-optimization/89794 * combine.c (count_auto_inc): New function. (try_combine): Count how many auto_inc expressions there were in the original instructions. Ensure we have the same number in the new instructions.

2019-01-16Fix ICE due to "combine" creating unreachable EH blocks (PR target/88861)David Malcolm1-6/+11
PR target/88861 reports an ICE in "ce2" due to an unreachable basic block. The block becomes unreachable in "combine" when delete_noop_moves deletes an insn with a REG_EH_REGION, deleting the EH edge, the only edge leading to the basic block. Normally, rest_of_handle_combine would call cleanup_cfg, deleting unreachable blocks, if combine_instructions returns true, and combine_instructions does return true for some cases of edge-removal, but it doesn't for this case, leading to the ICE. This patch updates delete_noop_moves so that it returns true if it deletes any edges, and passes that through to combine_instructions, so that it too will return true if any edges were deleted, ensuring that cleanup_cfg will be called by rest_of_handle_combine for this case, deleting the now-unreachable block, and fixing the ICE. gcc/ChangeLog: PR target/88861 * combine.c (delete_noop_moves): Convert to "bool" return, returning true if any edges are eliminated.

2018-10-22combine: Do not combine moves from hard registersSegher Boessenkool1-4/+46
On most targets every function starts with moves from the parameter passing (hard) registers into pseudos. Similarly, after every call there is a move from the return register into a pseudo. These moves usually combine with later instructions (leaving pretty much the same instruction, just with a hard reg instead of a pseudo). This isn't a good idea. Register allocation can get rid of unnecessary moves just fine, and moving the parameter passing registers into many later instructions tends to prevent good register allocation. This patch disallows combining moves from a hard (non-fixed) register. This also avoid the problem mentioned in PR87600 #c3 (combining hard registers into inline assembler is problematic). Because the register move can often be combined with other instructions *itself*, for example for setting some condition code, this patch adds extra copies via new pseudos after every copy-from-hard-reg. On some targets this reduces average code size. On others it increases it a bit, 0.1% or 0.2% or so. (I tested this on all *-linux targets).

2018-07-30combine: Allow combining two insns to two insnsSegher Boessenkool1-2/+20
This patch allows combine to combine two insns into two. This helps in many cases, by reducing instruction path length, and also allowing further combinations to happen. PR85160 is a typical example of code that it can improve. This patch does not allow such combinations if either of the original instructions was a simple move instruction. In those cases combining the two instructions increases register pressure without improving the code. With this move test register pressure does no longer increase noticably as far as I can tell. (At first I also didn't allow either of the resulting insns to be a move instruction. But that is actually a very good thing to have, as should have been obvious).
