Owen Anderson e4dcecd006 As Chris pointed out, this doesn't actually need an LLVMContext to operate.

 2009-07-13 21:27:19 +00:00
Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

Owen Anderson 2a15443aa8 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the 
moment, that I will need to make far-reaching changes.

Owen Anderson 1cf085d558 Hold the LLVMContext by reference rather than by pointer. 
llvm-svn: 74640
 2009-07-01 21:22:36 +00:00
Owen Anderson 6773d388aa Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

 2009-06-04 19:14:08 +00:00
Nick Kledzik cac8c8a9b3 <rdar://problem/6940611> libLTO.dylib needs to let linker specify path to assembler 
Add lto_codegen_set_assembler_path() API which allows the linker to specify the
path to the assembler tool to run.  When assembler is used (instead of compiler)
different command line options are used.
Add LTO_API_VERSION #define so clients (linkers) can conditionalize use of new APIs.

Daniel Dunbar 3cd724e590 Change LTO to run the global opt pass twice. 
- This matches llvm-ld.

It took a bit of archeology to figure out what the right thing to do was
(whether this was intentionally added or intentionally removed). My final
conclusion is that Chris added this intentionally here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=16913
but the changes weren't propogated to llvm-ld until here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=34058
which was after lto.cpp had been cloned off (of llvm-ld), here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=29494

From the commit message, it looks like the motivation for running global opt
again is because we ran it prior to inlining. Based on that I updated the
comment and also only run the pass if we actually ran the inliner.

Chris, please review.

Daniel Dunbar c292601287 Add createStandardLTOPasses to StandardPasses.h, and move lto and llvm-ld over. 
- I know it sounds crazy, but I think all the pass lists are now coalesced into
   StandardPasses.h.

Nick Lewycky a303097de0 Allow a user of libLTO to specify the full pathname of the gcc executable to 
run when assembling.

Wire this up to the gold plugin. You can now pass --plugin-opt gcc=/foo/bar/gcc
and it will run that gcc instead of looking for it on the path.

Bill Wendling 6598b95712 Remove LTO optimization level. 
llvm-svn: 70445
 2009-04-29 23:40:42 +00:00
Bill Wendling 026e5d7667 Instead of passing in an unsigned value for the optimization level, use an enum, 
which better identifies what the optimization is doing. And is more flexible for

Devang Patel 5606dd8a45 Using addPassesToEmitWholeFile is not a good idea here. 
Use FunctionPassManager to do the job.

Reid Spencer c295914b7a For PR797: 
Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be
executed. Only one case (in bugpoint) actually examines the result code.
