Charles Davis 1c8bd5ad7e Make the COFF streamer emit unwind info when processing a .seh_handlerdata
directive.

Implement emission of Win64 EH unwind info.

Pull in <cassert> in MCWin64EH.h so it can use the assert() macro.

Charles Davis 8e8f59bdfb A handler for a function in the Win64 EH scheme can be both an unwind handler
and an exception handler. Handle that case.

Also, add an 'Emitted' member to the MCWin64EHUnwindInfo struct. It will be
needed later.

Argyrios Kyrtzidis ac8bc12cd1 Add asserts in StringRef to make sure we avoid undefined behavior:
-strlen should not be called with NULL. Also guarantee that StringRef's Length is 0 if Data is NULL.
-memcmp should not be called with NULL (even if size is 0)

Andrew Trick f44aadf0fd indvars: Prototyping Sign/ZeroExtend elimination without canonical IVs.
No functionality enabled by default. Use -disable-iv-rewrite.
Extended IVUsers to keep track of the phi that represents the users' IV.
Added the WidenIV transform to replace a narrow IV with a wide IV
by doing a one-for-one replacement of IV users instead of expanding the
SCEV expressions. [sz]exts are removed and truncs are inserted.

Charles Davis de745ba396 Implement the EndProlog Win64 EH method on the base MCStreamer.

Charles Davis 7e6e8951af Implement the Win64 EH prolog instruction methods on the base MCStreamer.
I had to change the API slightly to avoid overloading issues.

Charles Davis 4cd8856704 Turns out GAS does have Win64 EH directives. (It also supports WinCE EH.) Make
ours compatible with GAS.

In retrospect, I should have emailed binutils about this earlier. Thanks to
Kai Tietz for pointing out that GAS already had SEH directives.

Charles Davis b4222589bf Implement the StartChained and EndChained Win64 EH methods on MCStreamer.

Francois Pichet 68610c1673 Fix the MSVC build.
Use a set of overloaded functions instead of template function for CreatePassFn.

It seems that template deduction for functions type that differs only by return type doesn't work with MSVC.

2011-05-19 02:54:11 +00:00
Charles Davis d991ec4e68 Implement the StartProc and EndProc Win64 EH methods on the base MCStreamer.
Based largely on Rafael Espindola's work on CFI. Other methods soon to follow.

2011-05-19 02:49:00 +00:00
Charles Davis 382c065822 Fix build issues with headers, which I discovered by actually using them.
Also, convert all the inline functions on UnwindInfo into methods.

Charles Davis bd5a09d3b2 Add a header patterned after MCDwarf.h for supporting Win64 exception handling
under MC.

Eli Friedman fadb03d6cc Third pass at allowing plugins to modify default passes. This time with a tweak so that we don't depend on an uninitialized argument.

2011-05-18 20:58:47 +00:00
Charles Davis 77e0610d7c Add some more Win64 EH directives:
- StartChained and EndChained delimit a chained unwind area, which can contain
  additional operations to be undone if an exception occurs inside of it.
- UnwindOnly declares that this function doesn't handle any exceptions. If it
  has a handler, it's an unwind handler instead of an exception handler.
- Lsda declares the location and size of the LSDA, which in the Win64 EH
  scheme is kept inside the UNWIND_INFO struct. Windows itself ignores the
  LSDA; it's used by the Language-Specific Handler (the "Personality Function"
  from DWARF).

Duncan Sands 3d9407f4eb Revert commit 131534 since it seems to have broken several buildbots.

Charles Davis 384041d0dc While thinking about how to know where the functions' boundaries are for
the purposes of the Win64 EH tables, I realized we had no way to tell where
the function ends. (MASM bounds functions with PROC and ENDP keywords.)
Add a directive to delimit the end of the function, and rename the 'frame'
directive to more accurately reflect its duality with the new directive.

Jakob Stoklund Olesen 4edf17d91f Teach LiveInterval::isZeroLength about null SlotIndexes.
When instructions are deleted, they leave tombstone SlotIndex entries.
The isZeroLength method should ignore these null indexes.

This causes RABasic to sometimes spill a callee-saved register in the
abi-isel.ll test, so don't run that test with -regalloc=basic.  Prioritizing
register allocation according to spill weight can cause more registers to be
used.

Eli Friedman 9ac944774f Basic fast-isel of extractvalue. Not too helpful on its own, given the IR clang generates for cases like this, but it should become more useful soon.
