Add template parameter debuginfo to generic types This changes debuginfo generation to add template parameters to generic types. With this change the DWARF now has DW_TAG_template_type_param for types, not just for functions, like: <2><40d>: Abbrev Number: 6 (DW_TAG_structure_type) <40e> DW_AT_name : (indirect string, offset: 0x375): Generic<i32> <412> DW_AT_byte_size : 4 <413> DW_AT_alignment : 4 ... <3><41f>: Abbrev Number: 8 (DW_TAG_template_type_param) <420> DW_AT_type : <0x42a> <424> DW_AT_name : (indirect string, offset: 0xa65e): T Closes #9224

rustc_target: separate out an individual alignment quantity type from Align. Before this PR, `rustc_target::abi::Align` combined "power-of-two alignment quantity" semantics, with a distinction between ABI (required) and preferred alignment (by having two quantities). After this PR, `Align` is only *one* such quantity, and a new `AbiAndPrefAlign` type is introduced to hold the pair of ABI and preferred `Align` quantities. `Align` is used everywhere one quantity is necessary/sufficient, simplifying some of the code in codegen/miri, while `AbiAndPrefAlign` only in layout computation (to propagate preferred alignment). r? @oli-obk cc @nagisa @RalfJung @nikomatsakis

Fix emission of niche-filling discriminant values Bug #55606 points out a regression introduced by #54004; namely that an assertion can erroneously fire when a niche-filling discriminant value is emitted. This fixes the bug by removing the assertion, and furthermore by arranging for the discriminant value to be masked according to the size of the niche. This makes handling the discriminant a bit simpler for debuggers. The test case is from Jonathan Turner. Closes #55606

2018-11-03Implement rotate using funnel shift on LLVM >= 7Nikita Popov-3/+3
Implement the rotate_left and rotate_right operations using llvm.fshl and llvm.fshr if they are available (LLVM >= 7). Originally I wanted to expose the funnel_shift_left and funnel_shift_right intrinsics and implement rotate_left and rotate_right on top of them. However, emulation of funnel shifts requires emitting a conditional to check for zero shift amount, which is not necessary for rotates. I was uncomfortable doing that here, as I don't want to rely on LLVM to optimize away that conditional (and for variable rotates, I'm not sure it can). We should revisit that question when we raise our minimum version requirement to LLVM 7 and don't need emulation code anymore.

2018-10-30Fix DWARF generation for enumsTom Tromey-144/+379
The DWARF generated for Rust enums was always somewhat unusual. Rather than using DWARF constructs directly, it would emit magic field names like "RUST$ENCODED$ENUM$0$Name" and "RUST$ENUM$DISR". Since PR #45225, though, even this has not worked -- the ad hoc scheme was not updated to handle the wider variety of niche-filling layout optimizations now available. This patch changes the generated DWARF to use the standard tags meant for this purpose; namely, DW_TAG_variant and DW_TAG_variant_part. The patch to implement this went in to LLVM 7. In order to work with older versions of LLVM, and because LLVM doesn't do anything here for PDB, the existing code is kept as a fallback mode. Support for this DWARF is in the Rust lldb and in gdb 8.2. Closes #32920 Closes #32924 Closes #52762 Closes #53153
