[mips] Make Static a default relocation model for MIPS codegen This change follows up defaults for GCC and Clang, so LLVM does not differ from them. While number of the test files are touched with this change, they all keep the old (expected) behaviour with the explicit option: "-relocation-model=pic" The tests that have not been touched are insensitive to relocation model.

llvm-dwarfdump: Replace -debug-dump=sect option with individual options. As discussed on llvm-dev in http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html this changes the command line interface of llvm-dwarfdump to match the one used by the dwarfdump utility shipping on macOS. In addition to being shorter to type this format also has the advantage of allowing more than one section to be specified at the same time. In a nutshell, with this change $ llvm-dwarfdump --debug-dump=info $ llvm-dwarfdump --debug-dump=apple-objc becomes $ dwarfdump --debug-info --apple-objc Differential Revision: https://reviews.llvm.org/D37714 llvm-svn: 312970

[dwarfdump] Pretty print location expressions and location lists Summary: Based on Fred's patch here: https://reviews.llvm.org/D6771 I can't seem to commandeer the old review, so I'm creating a new one. With that change the locations exrpessions are pretty printed inline in the DIE tree. The output looks like this for debug_loc entries: DW_AT_location [DW_FORM_data4] (0x00000000 0x0000000000000001 - 0x000000000000000b: DW_OP_consts +3 0x000000000000000b - 0x0000000000000012: DW_OP_consts +7 0x0000000000000012 - 0x000000000000001b: DW_OP_reg0 RAX, DW_OP_piece 0x4 0x000000000000001b - 0x0000000000000024: DW_OP_breg5 RDI+0) And like this for debug_loc.dwo entries: DW_AT_location [DW_FORM_sec_offset] (0x00000000 Addr idx 2 (w/ length 190): DW_OP_consts +0, DW_OP_stack_value Addr idx 3 (w/ length 23): DW_OP_reg0 RAX, DW_OP_piece 0x4) Simple locations without ranges are printed inline: DW_AT_location [DW_FORM_block1] (DW_OP_reg4 RSI, DW_OP_piece 0x4, DW_OP_bit_piece 0x20 0x0) The debug_loc(.dwo) dumping in changed accordingly to factor the code.

[PR27284] Reverse the ownership between DICompileUnit and DISubprogram. Currently each Function points to a DISubprogram and DISubprogram has a scope field. For member functions the scope is a DICompositeType. DIScopes point to the DICompileUnit to facilitate type uniquing. Distinct DISubprograms (with isDefinition: true) are not part of the type hierarchy and cannot be uniqued. This change removes the subprograms list from DICompileUnit and instead adds a pointer to the owning compile unit to distinct DISubprograms. This would make it easy for ThinLTO to strip unneeded DISubprograms and their transitively referenced debug info. Motivation ---------- Materializing DISubprograms is currently the most expensive operation when doing a ThinLTO build of clang. We want the DISubprogram to be stored in a separate Bitcode block (or the same block as the function body) so we can avoid having to expensively deserialize all DISubprograms together with the global metadata. If a function has been inlined into another subprogram we need to store a reference the block containing the inlined subprogram.

Clean up the processing of dbg.value in various places Summary: First up is instcombine, where in the dbg.declare -> dbg.value conversion, the llvm.dbg.value needs to be called on the actual loaded value, rather than the address (since the whole point of this transformation is to be able to get rid of the alloca). Further, now that that's cleaned up, we can remove a hack in the backend, that would add an implicit OP_deref if the argument to dbg.value was an alloca. This stems from before the existence of DIExpression and is no longer necessary since the deref can be expressed explicitly. Now, in order to make sure that the tests pass with this change, we need to correct the printing of DEBUG_VALUE comments to take into account the expression, which wasn't taken into account before. Unfortunately, for both these changes, there were a number of incorrect test cases (mostly the wrong number of DW_OP_derefs, but also a couple where the test itself was broken more badly). aprantl and I have gone through and adjusted these test case in order to make them pass with these fixes and in some cases to make sure they're actually testing what they are meant to test.

Re-apply "[mips] Use correct frame register for DWARF info when dynamically realigning the stack."" r252219 reversed the direction of subprogram -> function edge. Fixed the IR to account for this. llvm-svn: 252895
