2009-05-15Split out the DwarfDebug module from the DwarfWriter module.Bill Wendling
Again, no intendtional functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71854 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-15Split out the DwarfException class into its own file. No functionality change,Bill Wendling
though the classes have been marked with "VISIBILITY_HIDDEN". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71827 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-15Split out the Dwarf writer stuff into separate files. This is a much moreBill Wendling
logical/sane approach to organizing all of the stuff that goes into writing out DWARF information. Honestly? even this is too complex for what it's supposed to be doing. Trivia: It *looks* like there would be functionality changes, however there aren't! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71821 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-13There's yet more ugliness (surprise!) in DebugInfo. This needs major reworking.Bill Wendling
Basically, there was a situation where it was getting an empty vector and doing a .back() on that. Which isn't cool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71746 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Move the bookkeeping of the debug scopes back to the place where itBill Wendling
belonged. The variable declaration stuff wasn't happy with it where it was. Sorry that the testcase is so big. Bugpoint wasn't able to reduce it successfully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71714 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-12- Record that the debug info is actually used so that the label folder doesn'tBill Wendling
blast it away. - Move InlineInfo bookkeeping to bookkeep the correct debug info object. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71519 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-10This is a large rewrite of how Dwarf info for inlined functions is handled.Bill Wendling
The DwarfWriter expects DbgScopes and DIEs to behave themselves according to DwarfWriter's rules. However, inlined functions violate these rules. There are two different types of DIEs associated with an inlined function: an abstract instance, which has information about the original source code for the function being inlined; and concrete instances, which are created for each place the function was inlined and point back to the abstract instance. This patch tries to stay true to this schema. It bypasses how regular DbgScopes and DIEs are created and used when necessary. It provides special handling for DIEs of abstract and concrete instances. This doesn't take care of all of the problems with debug info for inlined functions, but it's a step in the right direction. For one thing, llvm-gcc generates wrong IR (it's missing some llvm.dbg intrinsics at the point where the function's inlined) for this example: #include <stdio.h> static __inline__ __attribute__((always_inline)) int bar(int x) { return 4; } void foo() { long long b = 1; int Y = bar(4); printf("%d\n", Y); } while clang generates correct IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71410 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-08Compute the offsets of the compile units. We need this so that when we emit aBill Wendling
concrete instance of an inlined function, we can get the actual address of the abstract instance inside of the compile unit. This isn't currently used, but will be by a future check-in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71263 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-07Revert 71165. It did more than just revert 71158 and it introducedDan Gohman
several regressions. The problem due to 71158 is now fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71176 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling
which better identifies what the optimization is doing. And is more flexible for future uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70440 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Second attempt:Bill Wendling
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70343 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13Right now, Debugging information to encode scopes (DW_TAG_lexical_block) ↵Devang Patel

2009-04-11Keep track of inlined functions and their locations. This information is ↵Devang Patel
collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions.

2009-04-09StringMap<DIE*>::iterator::first() returns a pointer to the first character ofBill Wendling
