2018-06-01DWARF5: Don't generate DW_AT_loclists_base for split compile unit DIEs.Mark Wielaard2-3/+14
The loclists_base attribute is used to point to the beginning of the loclists index of a DWARF5 loclists table when using DW_FORM_loclistsx. For split compile units the base is not given by the attribute, but is either the first (and only) index in the .debug_loclists.dwo section, or (when placed in a .dwp file) given by the DW_SECT_LOCLISTS row in the .debug_cu_index section. The loclists_base attribute is only valid for the full (or skeleton) compile unit DIE in the main (relocatable) object. But GCC only ever generates a loclists table index for the .debug_loclists section put into the split DWARF .dwo file. For split compile unit DIEs it is confusing (and not according to spec) to also have a DW_AT_loclists_base attribute (which might be wrong, since its relocatable offset won't actually be relocated). gcc/ChangeLog * dwarf2out.c (dwarf2out_finish): Remove generation of DW_AT_loclists_base.

2018-06-01[AArch64] Used prefer aliases SXTL(2) and UXTL(2)Kyrylo Tkachov2-2/+10
The SSHL and USHL instructions are used with a shift operand of zero to sign and zero-extend integer vectors into wider modes. GCC makes extensive use of them to "unpack" vectors. AArch64 defines a shorthand alias for that case. Instead of writing: SSHLL <Vd>.<Ta>, <Vn>.<Tb>, 0 we can write SXTL <Vd>.<Ta>, <Vn>.<Tb> Similar for the unsigned versions and the high-part versions (SSHL2 -> SXTL2). This makes the assembly of vectorised functions a bit more readable. * config/aarch64/aarch64-simd.md (aarch64_simd_vec_unpack<su>_lo_<mode>): Use UXTL and SXTL assembler mnemonics.

2018-06-01Fix phi backedge detection in backprop (PR85989)Richard Sandiford4-4/+63
This PR is a nasty wrong code bug due to my fluffing a test for a backedge in gimple-ssa-backprop.c. Backedges are supposed to be from definitions in the statement we're visiting to uses in statements that we haven't visited yet. However, the check failed to account for PHIs in the current block that had already been processed, so if two PHIs in the same block referenced each other, we'd treat both references as backedges. In more detail: The first phase of the pass goes through all statements in an arbitrary order, making optimistic assumptions about any statements that haven't been visited yet. The second phase then calculates a correct (supposedly maximal) fixed point. Although the first phase order is arbitrary in principle, we still use the CFG rpo to cut down on the backedges. This means that the only thing that's truly arbitrary is the order that we process the PHIs in a block. Any order should be OK and should eventually give the same results. But we have to follow whatever order we pick, and the pass wasn't doing that. 2018-06-01 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR tree-optimization/85989 * gimple-ssa-backprop.c (backprop::m_visited_phis): New member variable.

r254152 disabled partial_reg_dependency and movx for Haswell and newer Intel processors. r258972 restored them for skylake-avx512. For Haswell, movx improves performance. But partial_reg_stall may be better than partial_reg_dependency in theory. We will investigate performance impact of partial_reg_stall vs partial_reg_dependency on Haswell for GCC 9.
