Add a "debugger tuning" concept that allows us to fine-tune how we emit debug info, according to the preferences of the different debuggers used on various targets. Darwin and FreeBSD default to tuning for LLDB; PS4 defaults to tuning for the SCE (Sony Computer Entertainment) debugger. All others default to GDB.

Rewrite debugger tuning test case to not depend on apple sections Summary: In a follow-up commit I'll change the rules for emission of accelerator tables, which means we won't be able to use them as a litmus test for the debugger tuning options. Instead of sections, I base the test on the presence/absence of some debug info attributes and opcodes: LLDB - prefers DW_OP_form_tls_address and uses DW_AT_APPLE_optimized GDB - prefers DW_OP_GNU_push_tls_address and does not use the optimized attribute SCE - prefers DW_OP_form_tls_address and does not use the optimized attribute Reviewers: probinson, aprantl, dblaikie Subscribers: JDevlieghere, llvm-commits Differential Revision: https://reviews.llvm.org/D41985 llvm-svn: 322630

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label. In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.
