 2011-08-09 23:26:12 +00:00
Eli Friedman 59b66883ea Representation of 'atomic load' and 'atomic store' in IR.

 2011-08-09 23:02:53 +00:00
Eli Friedman 84cd7927b9 First draft of the practical guide to atomics. 
This is mostly descriptive of the intended state once atomic load and store have landed.

llvm-svn: 136866
 2011-08-04 10:43:43 +00:00
Bill Wendling 2d3138c112 Remove the LowerSetJmp pass. It wasn't used effectively by any of the targets. 
This is some of my original LLVM code. *wipes tear*

llvm-svn: 136821
 2011-08-03 22:18:20 +00:00
Bill Wendling c5a136103b Go back to the old definition. It's not clear that a 'resume' can be 'outlined' from the function with the landing pad for all platforms. 
llvm-svn: 136799
 2011-08-03 18:37:32 +00:00
Bill Wendling 0524b8d1f4 Explain how clauses are applied. 
llvm-svn: 136790
 2011-08-03 17:17:06 +00:00
Bill Wendling bbcb7cde34 Add the documentation for the 'landingpad' instruction. Improve the 'invoke' 
instruction's documentation to reference the landingpad and resume instructions.

 2011-08-02 21:52:38 +00:00
Chris Lattner d3d65ab791 no need to count the terminators. 
llvm-svn: 136718
 2011-08-02 20:29:13 +00:00
Bill Wendling 6bc7caa334 Duncan's english is better than mine. :-) 
llvm-svn: 136684
 2011-08-02 06:39:13 +00:00
Bill Wendling 46ffaa95bd Remove the LLVMBuildUnwind C API function. 
The 'unwind' function is going away with the new EH rewrite. This is step 0 in
keeping front-ends from using it.

John McCall c26ea5a51a I am the code owner for Clang's IR generation; this has been true 
for awhile, but it's good to make this official.  

Just to be clear, Doug and Ted "elected" me to this position.

Might as well add myself to the credits list while I'm at it.

llvm-svn: 136590
 2011-07-31 06:45:03 +00:00
Bill Wendling f891bf8b30 Add the 'resume' instruction for the new EH rewrite. 
This adds the 'resume' instruction class, IR parsing, and bitcode reading and
writing. The 'resume' instruction resumes propagation of an existing (in-flight)
exception whose unwinding was interrupted with a 'landingpad' instruction (to be
added later).

Eli Friedman c9a551ebed LangRef and basic memory-representation/reading/writing for 'cmpxchg' and 
'atomicrmw' instructions, which allow representing all the current atomic
rmw intrinsics.

The allowed operands for these instructions are heavily restricted at the
moment; we can probably loosen it a bit, but supporting general
first-class types (where it makes sense) might get a bit complicated,
given how SelectionDAG works.

As an initial cut, these operations do not support specifying an alignment,
but it would be possible to add if we think it's useful. Specifying an
alignment lower than the natural alignment would be essentially
impossible to support on anything other than x86, but specifying a greater
alignment would be possible.  I can't think of any useful optimizations which
would use that information, but maybe someone else has ideas.

Optimizer/codegen support coming soon.

 2011-07-26 07:58:09 +00:00
Eli Friedman fee02c6c13 Initial implementation of 'fence' instruction, the new C++0x-style replacement for llvm.memory.barrier. 
This is just a LangRef entry and reading/writing/memory representation; optimizer+codegen support coming soon.
