2020-10-15tree-optimization/97482 - fix split_constant_offset of nop-conversionsRichard Biener3-1/+48
split_constant_offset is confused about a nop-conversion from unsigned long to sizetype and tries to prove non-overflowing of the inner operation. Obviously the conversion could have been elided so make sure split_constant_offset handles this properly. It also makes sure that convert_to_ptrofftype does not introduce conversions not necessary which in this case is the source for the unnecessary conversion. 2020-10-15 Richard Biener <rguenther@suse.de> PR tree-optimization/97482 * tree-data-ref.c (split_constant_offset_1): Handle trivial conversions better. * fold-const.c (convert_to_ptrofftype_loc): Elide conversion if the offset is already ptrofftype_p. * gcc.dg/vect/pr97428.c: New testcase.

2020-10-14libgo: export NetBSD-specific types in mksysinfo.shNikhil Benesch1-1/+1
The syscall package depends on many NetBSD-specific types on NetBSD. Teach mksysinfo.sh to export these types. This alone is not sufficient to get the syscall package to compile on NetBSD, but it's a start. Note that the IfMsgHdr type is recapitalized to IfMsghdr, which requires changes in the AIX port. The new capitalization is what's used by upstream in existing NetBSD-specific code and is more consistent with the capitalization of other C structs with the "hdr" suffix. Updates golang/go#38538.

2020-10-14runtime: correct semaphore implementation on netbsdNikhil Benesch1-1/+1
NetBSD's semaphores use the underlying lighweight process mechanism (LWP) on NetBSD, rather than pthreads. This means the m.prodcid needs to be set to the LWP ID rather than the pthread ID in order for unpark notifications to get sent to the right place. Introduce a new getProcID() method that selects the correct ID for the platform. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/261742

2020-10-14i386: Improve chaining of _{addcarry,subborrow}_u{32,64} [PR97387]Jakub Jelinek4-12/+132
These builtins have two known issues and this patch fixes one of them. One issue is that the builtins effectively return two results and they make the destination addressable until expansion, which means a stack slot is allocated for them and e.g. with -fstack-protector* DSE isn't able to optimize that away. I think for that we want to use the technique of returning complex value; the patch doesn't handle that though. See PR93990 for that. The other problem is optimization of successive uses of the builtin e.g. for arbitrary precision arithmetic additions/subtractions. As shown PR93990, combine is able to optimize the case when the first argument to these builtins is 0 (the first instance when several are used together), and also the last one if the last one ignores its result (i.e. the carry/borrow is dead and thrown away in that case). As shown in this PR, combiner refuses to optimize the rest, where it sees: (insn 10 9 11 2 (set (reg:QI 88 [ _31 ]) (ltu:QI (reg:CCC 17 flags) (const_int 0 [0]))) "include/adxintrin.h":69:10 785 {*setcc_qi} (expr_list:REG_DEAD (reg:CCC 17 flags) (nil))) - set pseudo 88 to CF from flags, then some uninteresting insns that don't modify flags, and finally: (insn 17 15 18 2 (parallel [ (set (reg:CCC 17 flags) (compare:CCC (plus:QI (reg:QI 88 [ _31 ]) (const_int -1 [0xffffffffffffffff])) (reg:QI 88 [ _31 ]))) (clobber (scratch:QI)) ]) "include/adxintrin.h":69:10 350 {*addqi3_cconly_overflow_1} (expr_list:REG_DEAD (reg:QI 88 [ _31 ]) (nil))) to set CF in flags back to what we saved earlier. The combiner just punts trying to combine the 10, 17 and following addcarrydi (etc.) instruction, because if (i1 && !can_combine_p (i1, i3, i0, NULL, i2, NULL, &i1dest, &i1src)) { if (dump_file && (dump_flags & TDF_DETAILS)) fprintf (dump_file, "Can't combine i1 into i3\n"); undo_all (); return 0; } fails - the 3 insns aren't all adjacent and || (! all_adjacent && (((!MEM_P (src) || ! find_reg_note (insn, REG_EQUIV, src)) && modified_between_p (src, insn, i3)) src (flags hard register) is modified between the first and third insn - in the second insn. The following patch optimizes this by optimizing just the two insns, 10 and 17 above, i.e. save CF into pseudo, set CF from that pseudo, into a nop. The new define_insn_and_split matches how combine simplifies those two together (except without the ix86_cc_mode change it was choosing CCmode for the destination instead of CCCmode, so had to change that function too, and also adjust costs so that combiner understand it is beneficial). With this, all the testcases are optimized, so that the: setc %dl ... addb $-1, %dl insns in between the ad[dc][lq] or s[ub]b[lq] instructions are all optimized away (sure, if something would clobber flags in between they wouldn't, but there is nothing that can be done about that). 2020-10-14 Jakub Jelinek <jakub@redhat.com> PR target/97387 * config/i386/i386.md (CC_CCC): New mode iterator.
