2013-03-12Debug Info: use DW_FORM_ref_addr instead of DW_FORM_ref4 if the referenced DIEManman Ren
belongs to a different compile unit. DW_FORM_ref_addr should be used for cross compile-unit reference. When compiling a large application, we got a dwarfdump verification error where abstract_origin points to nowhere. This error can't be reproduced on any testing case in MultiSource. We may have other cases where we use DW_FORM_ref4 unconditionally. rdar://problem/13370501 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176882 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-11Remove support for versioned debug info.David Blaikie
Versioned debug info support has been a burden to maintain & also compromised current debug info verification by causing test cases testing old debug info to remain rather than being updated to the latest. It also makes it hard to add or change the metadata schema by requiring various backwards-compatibility in the DI* hierarchy. So it's being removed in preparation for new changes to the schema to tidy up old/unnecessary fields and add new fields needed for new debug info (well, new to LLVM at least). The more surprising part of this is the changes to DI*::Verify - this became necessary due to the changes to AsmWriter. AsmWriter was relying on the version test to decide which bits of metadata were actually debug info when printing the comment annotations. Without the version information the tag numbers were too common & it would print debug info on random metadata that happened to start with an integer that matched a tag number. Instead this change makes the Verify functions more precise (just adding "number of operands" checks - not type checking those operands yet) & relies on that to decide which metadata is debug info metadata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176838 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-07Debug Info: store the files and directories for each compile unit.Manman Ren
We now emit a line table for each compile unit. To reduce the prologue size of each line table, the files and directories used by each compile unit are stored in std::map<unsigned, std::vector< > > instead of std::vector< >. The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each compile unit causes a huge increase of debug info. With this patch, each prologue will only emit the files required by the compile unit. rdar://problem/13342023 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176605 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06Handle non-default array bounds.Bill Wendling
Some languages, e.g. Ada and Pascal, allow you to specify that the array bounds are different from the default (1 in these cases). If we have a lower bound that's non-default, then we emit the lower bound. We also calculate the correct upper bound in those cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169484 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling
The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169312 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Add a 'count' field to the DWARF subrange.Bill Wendling
The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169218 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-13Use the 'count' attribute instead of the 'upper_bound' attribute.Bill Wendling
If we have a type 'int a[1]' and a type 'int b[0]', the generated DWARF is the same for both of them because we use the 'upper_bound' attribute. Instead use the 'count' attrbute, which gives the correct number of elements in the array. <rdar://problem/12566646> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167806 91177308-0d34-0410-b5e6-96231b3b80d8
