* Reapply an improved version of r180816/180817.Adrian Prantl2013-07-093-5/+115
| | | | | | | | | | | | | | | Change the informal convention of DBG_VALUE machine instructions so that we can express a register-indirect address with an offset of 0. The old convention was that a DBG_VALUE is a register-indirect value if the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE is register-indirect if the first operand is a register and the second operand is an immediate. For plain register values the combination reg, reg is used. MachineInstrBuilder::BuildMI knows how to build the new DBG_VALUES. rdar://problem/13658587 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185966 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: PR14728: TLS supportDavid Blaikie2013-06-281-0/+34
| | | | | | | | | | | | | | Based on GCC's output for TLS variables (OP_constNu, x@dtpoff, OP_lo_user), this implements debug info support for TLS in ELF. Verified that this output is correct/sufficient on Linux (using gold - if you're using binutils-ld, you'll need something with the fix for http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it). Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks want to discuss (or just go ahead & implement) how this should work in MachO, etc, I'm open. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185203 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: clean up usage of Verify.Manman Ren2013-06-281-4/+4
| | | | | | | | | | | | No functionality change. It should suffice to check the type of a debug info metadata, instead of calling Verify.

* DebugInfo: PR14763/r183329 correct the location of indirect parametersDavid Blaikie2013-06-191-0/+70
| | | | | | | | | | | | | | | | We had been papering over a problem with location info for non-trivial types passed by value by emitting their type as references (this caused the debugger to interpret the location information correctly, but broke the type of the function). r183329 corrected the type information but lead to the debugger interpreting the pointer parameter as the value - the debug info describing the location needed an extra dereference. Use a new flag in DIVariable to add the extra indirection (either by promoting an existing DW_OP_reg (parameter passed in a register) to DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n (parameter passed on the stack). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184368 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | DW_TAG_subroutine_type There were bits & pieces of code lying around that may've given the impression that debug info metadata supported the possibility that a subprogram's type could be specified by a non-subroutine type describing the return type of a void function. This support was incomplete & unnecessary. Asserts & API have been changed to make the desired usage more clear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182532 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | This is to fix PR15408 where an undefined symbol Lline_table_start1 is used. Since we do not generate the debug_line section when .loc is used, Lline_table_start1 is not emitted and we can't refer to it when calculating at_stmt_list for a compile unit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182344 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | Adding another CU-wide list, in this case of imported_modules (since they should be relatively rare, it seemed better to add a list where each element had a "context" value, rather than add a (usually empty) list to every scope).

| | | | | | | | | | | | This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc).
