* Compute the offsets of the compile units. We need this so that when we emit aBill Wendling2009-05-081-11/+20
| | | | | | | | | 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. llvm-svn: 71263
* Minor clean ups. No functionality change.Bill Wendling2009-05-081-5/+4

* Revert 71165. It did more than just revert 71158 and it introducedDan Gohman2009-05-071-140/+57

* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-291-3/+3
| | | | | | | which better identifies what the optimization is doing. And is more flexible for future uses. llvm-svn: 70440
* Second attempt:Bill Wendling2009-04-291-5/+5
| | | | | | | | | | | | 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. llvm-svn: 70343

* Reapply 68847.Devang Patel2009-04-131-3/+127
| | | | | | Now debug_inlined section is covered by TAI->doesDwarfUsesInlineInfoSection(), which is false by default. llvm-svn: 68964
* Add a new "available_externally" linkage type. This is intendedChris Lattner2009-04-131-0/+3
| | | | | | | | to support C99 inline, GNU extern inline, etc. Related bugzilla's include PR3517, PR3100, & PR2933. Nothing uses this yet, but it appears to work. llvm-svn: 68940
* Revert r68847. It breaks the build on non-Darwin targets, with this messageDan Gohman2009-04-111-124/+3
| | | | | | | from the assembler: Error: unknown pseudo-op: `.debug_inlined' llvm-svn: 68863
* Keep track of inlined functions and their locations. This information is ↵Devang Patel2009-04-111-3/+124
| | | | | | | | 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. See DwarfWriter.cpp for more information on structure of debug_inlined section. llvm-svn: 68847

* StringMap<DIE*>::iterator::first() returns a pointer to the first character ofBill Wendling2009-04-091-3/+3
| | | | | | | | the key. This will cause it to create a new std::string, which isn't wanted. Instead, pass back the "const char*". Modify the EmitString() method to take a "const char*". llvm-svn: 68741
* Use a StringMap instead of std::map for storing std::string->DIE* maps. ThisBill Wendling2009-04-091-10/+10

| | | | | | | | | | | the untimed version of getOrCreateSourceID. getOrCreateSourceID calls GetOrCreateSourceID, of course. - Move some methods into the "private" section. Constify at least one method. - General clean-ups. llvm-svn: 66582
* Refine the Dwarf writer timers so that they measure exception writing and debugBill Wendling2009-03-101-143/+169

* Pass in a std::string when getting the names of debugging things. This cuts downBill Wendling2009-03-091-20/+37
| | | | | | on the number of times a std::string is created and copied. llvm-svn: 66396
* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-7/+10
| | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. llvm-svn: 66339
