Eric Christopher 4996c70034 Add the support code to enable the dwarf accelerator tables. Upcoming patches

Nick Lewycky d1ee7f8cf1 Don't emit a directory entry for the value in DW_AT_comp_dir, that is always 
implied by directory index zero.

Nick Lewycky 40f8f2ff24 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

Devang Patel 0ecbcbd12c Eliminate unnecessary forwarding function.

Devang Patel eb1bb4e419 Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. 
MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up.

Devang Patel 07bb9eea33 Refactor. 
llvm-svn: 137689
 2011-08-15 23:47:24 +00:00
Devang Patel 1f4f98d664 Continue to hoist uses of getCompileUnit() up. The goal is to get rid of uses of getCompileUnit(). 
llvm-svn: 137683
 2011-08-15 23:36:40 +00:00
Devang Patel d2dfc5ec02 This is somewhat déjà-vu, but avoid using getCompileUnit() as much as possible. 
llvm-svn: 137668
 2011-08-15 22:24:32 +00:00
Devang Patel 3acc70e536 Refactor. Variables are part of compile unit so let CompileUnit create new variable. 
llvm-svn: 137663
 2011-08-15 22:04:40 +00:00
Devang Patel d899444347 There is no need to maintain a set to keep track of variables that use location expressions. In such cases, AT_location attribute's value will be a label.

 2011-08-15 21:24:36 +00:00
Devang Patel 99819b527d Simplify mapping to variable from its abstract variable info. 
When a variable is inlined multiple places, abstract variable keeps name, location, type etc.. info and all other concreate instances of the variable directly refers to abstract variable.

Devang Patel 3e021533cd Teach dwarf writer to handle complex address expression for .debug_loc entries. 
This fixes clang generated blocks' variables' debug info.

 2011-04-28 02:22:40 +00:00
Devang Patel f20c4f715f This mechanical patch moves type handling into CompileUnit from DwarfDebug. In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious. 
llvm-svn: 129402

Jakob Stoklund Olesen 9a624fa993 Collect and coalesce DBG_VALUE instructions before emitting the function. 
Correctly terminate the range of register DBG_VALUEs when the register is
clobbered or when the basic block ends.

The code is now ready to deal with variables that are sometimes in a register
and sometimes on the stack. We just need to teach emitDebugLoc to say 'stack
slot'.

llvm-svn: 128327
 2011-03-26 02:19:36 +00:00
Jakob Stoklund Olesen 1886a4c823 Emit less labels for debug info and stop emitting .loc directives for DBG_VALUEs. 
The .dot directives don't need labels, that is a leftover from when we created
line number info manually.

Instructions following a DBG_VALUE can share its label since the DBG_VALUE
doesn't produce any code.

Devang Patel e01b75cb89 Keep track of directory namd and fIx regression caused by Rafael's patch r119613. 
A better approach would be to move source id handling inside MC.

Jakob Stoklund Olesen ec0ac3ca40 Reapply r128045 and r128051 with fixes. 
This will extend the ranges of debug info variables in registers until they are
clobbered.

Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on
the stack with DBG_VALUE instructions referring to variables in the frame
pointer. This fixes the gdb test-suite failure.

Fix 2: Don't trace through copies to physical registers setting up call
arguments. These registers are call clobbered, and the source register is more
likely to be a callee-saved register that can be extended through the call
instruction.

Andrew Trick b0f98bb5e9 Revert r128045 and r128051, debug info enhancements. 
Temporarily reverting these to see if we can get llvm-objdump to link. Hopefully this is not the problem.

Jakob Stoklund Olesen 9c057ee440 Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges. 
These ranges get completely jumbled by the post-ra scheduler, and it is not
really reasonable to expect it to make sense of them.

Instead, teach DwarfDebug to notice when user variables in registers are
clobbered, and terminate the ranges there.

Devang Patel 6c622ef1bc If argument numbering is encoded in metadata then emit arguments' debug info in that order.
